2000 Rodeo, wipers work when on, no intermittent control. They just stop where ever they are if you swtich to intermittent control. I've heard this is a module above the glove box that costs about $200. Is it parts on the board in the module that fail so the module has to be replaced, or can I open the module, resolder grounds etc and restore operation? If not, anywhere less expensive than the dealer to get a replacement module?

find a junked rodeo in your area and pick and pull the part.

Same happened to mine. It is the alarm module located under the glove box on the side wall. It's grey and is located above a smaller black box which I think is the keyless entry reciever. The replacement unit cost a fortune here in Australia so I opened mine and fixed it. It requires a simple $1 relay replacement. If your smart with electronics you can identify the relay by shorting the correct legs to identify the one. There are three large ones from what i can remember. Sorry, didn't document what I did.
I'd be careful using a 2nd hand one as you will probably have the same thing happen again. The original relays are cheap and just wear out i think. Worth a shot. By the way, that anoying buzzer is on this board. You can place some tape over it to muffle the buzz while your there.

Cool! Just what I was hoping to hear. I can handle that, low voltage systems (fire, nurse call, etc) is part of what I do. Don't do trouble shooting down to componenet level on circuit boards, but a relay change out is no sweat. Thanks for the reply!

Well I did it. I pulled the module, opened it and pulled out the circuit board. Took a little while to determine which of the relays was the one for the front wipers. Being late on a Saturday, was too late to find an open electronics supply house, so I found a relay at Radio Shack. The coil had a nominal voltage of 9 volts, but the contacts were rated at 12 amps and it was the right size and configuration to solder right to the board. Worked great. Only spent $5 on the relay, and $7 for a solder removal tool. Would only recommend attempting this if you have some experience messing with electronics, circuit boards, volt/ohm meters, and soldering.

A BIG thanks to 2000Frontera in Australia who told me what to do!!

Well done! Sure beats the hell out of paying for a new one. Seems to be a few owners with older models starting to suffer this. Perhaps you could start a little business over there. They mail them to you and for a nominal fee you could repair them.

You know the thought crossed my mind. But I'd have to have some kind of test rig to check them out before and after repairs so I wouldn't have to test each on on my vehicle. Also, don't know what else that board does, would probably end up getting boards with other problems and get caught in the "Well it was working before I sent it to you" trap.

I will be placeing this soon since I have the same problem. I have located a replacment board for 30 bucks, so I will have my old one for parts. I removed the old part tonight. I do not have the factory so there was no black black to move. Also the board was in a brownish colored plastic box instead of the noted gray (I have a 2000).

It took me about 20 minutes to pull it out and then put it back in. I'm sure, now I know what I'm doing, I can do it in under 10 minutes. Hope the used part works. If not, well then I can practice my soldering skills on the used part and not worry if I mess it up.

I've got intermittent wipers again.

Thanks for the good work men. With out you guys sharing this information I would have been out ~$250 (USD)

I got my relays from Mouser last Wednesday and installed one last night. Eureka it worked! The relay cost $5.10 (USD).

I had to call the US Fujitsu distributor and ask them to sell 4 relays to Mouser to resale to me. It took three weeks to get that finalized. Besides that, getting the relay off the circuit board was the biggest chore for this fix. Well worth the trouble.

Now that you have the supply chain set up, I'd gladly buy a few of these relays from you if you could get more (marked up for your trouble of course!).

I don't have an agreement with Mouser to buy quantities less than 125.

What I did have was an agreement with Fujitsu to sell Mouser 4 relays to re-sale to me. Its my understanding that Mouser can only buy and sell lots of 125 from Fujitsu. Mouser doesn't stock this part.

I can only hope that if enough people contacted Mouser wanting to buy these relays they might stock and sell quantities of one zees and two zees.

I've sent an email to mouser with a request to by 10 more. If I can buy ten I'll sell those.

Update 08 Dec 04
Mouser responded, "We have 0 stock on this part and our minimum order requirement is 125 pieces. You will have to get approval from Fujitsu to order a lesser amount."

Does anyone want to organize a group buy? I've never done it. Not sure how it works.

Is the rear wiper also controlled by this circuit board?

I am having no problems out of the front set of wipers, but the rear will work once out of 50 times I turn on the switch.

If it is controlled off of this board which relay is it?

Thanks,

Provided your truck has a similar A&C unit, the upper left relay marked P1NO12N is the rear wiper (see the above picture). In the picture the front wiper relay is circled.

Here's a link (http://www.automotiveforums.com/vbulletin/showthread.php?t=243753) to a thread where KJK swapped the relays and fixed his front. His rear stopped working.

Actually, the relay to the left of the circled one in the picture is the rear wiper delay. When I "fixed" my front wiper delay problem I couldn't find a proper relay so I just swapped the position of those two relays because I never used the rear wiper.

will any 12volt relay work on this provided leads can be added to match up with the holes? The reason I ask is I work commercial access control (card access) and have "ice cube" type relays laying around everywhere. I'd like to just use on of those. Is there anything special about the relays mentioned above other than the foot print being the same?

I'm hopeful this will solve the problem. I priced the Alarm Control Unit from Honda locally and it is orderable at $208.00. If I can fix this for $10 I'll be a happy camper.

I have two Isuzu Rodeos, a 2000 and a 2001. I too had the same problem with the wiper failure first with the rear wiper in January and then about a month ago with the front wipers on the 2000 Rodeo. I verified that the problem was NOT with the wiper motor and didn't know what to do next, so I searched the web and luckily found your postings!! :) I contacted ISUZU to see if they had a recall on this board problem because it clearly is pervasive on ISUZUs. Unfortunately there is no recall.
So I followed your instructions and obtained 4 relays from Mouser because I fully expect my 2001 Rodeo to have this issue sooner or later! I received them this weekend and successfully installed two relays on the 2000 Rodeo with wiper problems. This solved my wiper problems on both the front and rear. Let me add that I am NO auto repair expert, rather someone along the lines of a shady tree mechanic trying to keep cars on the road without huge shop bills.
I thank all of you very much for your well documented postings and the photo of the board!!!
I'd like to add one more hint on replacing the relays.... I utilized Radio Shack Desoldering Braid Catalog no. 64-2090B to remove the solder holding the old relays onto the board. This braid acts like a vacuum absorbing the solder so it doesn't mess up other board components.

What about a '99 Rodeo that has Omron relays on the alarm control board? Does the same thing apply as far as being able to but a single replacement relay and soldering it into the circuit board? I have pulled the ACB out and see 3 relays similar to what was described earlier on this thread. Any one ever run into Omron G8QN-01 relays and know of a place to buy one.

Also, if I'm able to get a good price on the whole replacement board, is the connector to the board soldered to the board? My connector is green plastic and looks to have 2 pins that stick into the connector and when you turn the board over, it looks like the other end of the pins are a large soldered connection.

Any help is appreciated.

I keep reading again but I may be missing something. Is the relay only for the intermittent setting or for overall operation. I'm asking because my front wipers stopped working yesterday in the middle of a downpour (of course). They just stopped in mid-stroke. When I try to turn them on they don't move but I can hear what sounds like the motor working. Also the fuse is fine.
Any response is appreciated.

Hi all! I'm new to this forum, but you guys have saved me time and money. I had same issues of front and rear wiper stopping or not working at all. I bought three new relays from mouser and got the front wipers and intermittent delay working, The rear however refuses to go further than a few inches. Does anybody know which relay controls the rear wiper and their intermittent control? Does anybody have a picture or listing layout of the alarm control unit so someone like me can easily identify locations and what each item does?

Thanks again for the time and money saved so far.

The picture is on the first page of this thread. The circled relay in the picture is the front wiper delay. The relay immediately to the left of it (on the same row) is the rear wiper delay.

I had problems with the front wipers on my 2000 rodeo ls, and just completed the replacement of the front wiper relay (ordered from Mouser) as discussed in this thread. It worked perfectly! So I wanted to share specifics of my experience in case they may help others to identify and fix their problems.

Standard disclaimer -- USE AT YOUR OWN RISK.

First, here are the exact symptoms that I saw:
- when the wipers were parked (at the low resting postition), turning them to intermittent would bring them up about a third of the way, and then they would stop and not move again unless I switched to low or high speed.
- low and high speeds worked fine, except that if I turned the wipers from low or high to off or intermittent, they would simply stop at whatever position they were at. Only way to get them to the parked position was to turn them off at the perfect spot in the arc.

I read on this forum that it was probably the alarm control unit that was causing this problem, but I wanted to be sure so I got the wiring diagram for the front wiper system. This showed me that there are basically three components to the system:
1. the selector wand (multi-position switch) on the steering wheel. This actually consists of two switches and a variable resistor or some such for the intermittent interval.
2. the alarm control unit
3. the windshield wiper motor assembly, which basically includes the motor plus a switch that detects whether the wipers are parked. (at the low resting position)

I concluded that the windshield wiper system basically has 2 modes -- "run" and "park". When turned to low or high speed, the system is forced into "run" mode, and everything works fine. But for intermittent operation, and to get the wipers back to the parked position when the wipers are turned off in mid stroke, the "park" mode is heavily used. (more specifically, intermittent is basically the computer jolting the wipers out of the parked position, and then letting park mode take over to let them return to the parked position.)

It seemed like the park mode was basically broken.

With the battery disconnected and the computer disconnected (because I didn't want to accidentally fry it with the current from the continuity tester), I tested the three switches in the system using the continuity tester. They were fine, so I concluded that the computer was probably at fault. So I decided to try replacing the relay.

Next up... putting in the relay. First I had to get the computer (a.k.a. alarm control module) out. Based on advice from this forum, I removed the glove box using the two screws underneath, disconnected the wires from the alarm control module (ACM) then found the screw directly under the ACM (hidden by some wires) and removed it. This allowed me to remove the ACM without removing the box below it. With the ACM out, opening it up was easy -- the black face on the connector side is removed by unclipping the 3 clips holding it in place, and then the board slid out of the box.

Based on the picture shown in the thread, I went about removing the front wiper relay. This was definitely the hard part, as I'm not an expert solderer. (or de-solderer) I had purchased some de-soldering braid for radio shack, and found it tricky to use, but eventually got the hang of it. Specifically, I had to find the 5 soldered pins on the back of the circuit board that corresponded to the 5 pins on the relay, and carefully remove the solder for each one. I tried placing the braid on top of the pin and punching the pin through the braid, then heating the braid, but this didn't really work. In the end the best way to do it was to push the braid up against the side of the pin, hold the soldering iron against the braid, and wait for the solder to flow into the braid.

Even with the solder "removed" from all 5 pins, I still had some trouble working the relay out, but I did so very slowly and it eventually came out.

Putting the new one in was a little easier. I use a pointy object (small safety pin end) to clean out the holes a bit, and slowly worked the new relay into the hole pattern. Soldering was easy... just held the iron against one side of each pin, and touched some solder to the other side of the pin.

After that I put it all together and it worked!

Thanks to all on this thread for the great info. Saved me somewhere between 200 and 350 bucks!

cool, I am most positive they are correct. I ordered one of each back in November and the NEC lined up perfect. I put in the other since it was the OEM. I am pretty sure many others have used the NEC though.

It had been years since I last soldered and I managed to get it. It takes patience though. Good luck with it, it isn't too hard though.

find a junked rodeo in your area and pick and pull the part.

Have found the needed ALARM MODULE at a "junk yard" with the same part number as I was given at the dealership Parts Dept. for a NEW one. However, the junk part is off a '99 Honda Passport - NOT an Isuzu Rodeo. Inasmuch as Isuzu manufactures the Passport for Honda, and they are IDENTICAL (except for the Honda insignia), may I presume that this part will work in both vehicles.

I ask because when I called the dealer parts dept. I was asked which MONTH in 1999 was the vehicle manufactured, as there are THREE different circuit boards on the '99 modules!!!!!!

ALSO... there's a good chance that this part off a junk vehicle DOES NOT WORK any better than the one on my vehicle. The salvage place cannot verify that the circuits and relays are in "working condition". If this part does NOT resolve my intermittent wiper (and rear wiper) problems can I insist that they take it back? They said they only "exchange", but very unlikely that they have very many of these particular circuit boards.

Thanks for any input here.

Artchee, There is no way to make sure the used alarm module will work unless they will let you plug it in in the parking lot before purchasing it. Even then it may go out as soon as you leave the place. Those are the chances you take buying used parts. I don't know anything about the 3 different boards depending in what month your truck was made, but they all probably do the same thing just in different routings. I would ask to size it up at the yard. You can drive your rodeo with everything already disassembled and then all you have to do is pull your box out when you get there and plug theirs in. If it works, great. If not, then the soldering to replace your own relays is really simple. Anyone can do it. All it takes is 2 screws in the bottom of the glove box to remove it and then you can easily get to your alarm box. There are a few good listing in this post on how to do it.
Hope this helps.

Did you recheck the plug connections on the box? If the plug isn't seated correctly you can have inconsistant contact with the leads and the wipers won't work all the time. When I fixed mine, I thought I had done something wrong because the wipers would reset back to the start position, but the intermitten setting wasn't working. After pulling it apart and rechecking all my solder connection I realized the plug wasn't seating correctly even though it looked like it was good to go. Once I got that squared away, I haven't had any problems. I used the NEC 22111 relays, but I guess the 3100 are even closer to specs then the 22111. I also replaced all 3 relays at one time.

Rodeo4me,

I agree with Chapy, check your conection and solder joints first.

There are 2 relays which control the rear wiper with my box. I'm not sure exactly what the second one does but grounding the common pin for the contacts opereated the rear wiper. Check http://forum.planetisuzoo.com/viewtopic.php?t=5608 for what my board looks like and which relays did what. I always suggest to replace all 3 at the same time, the relays are cheap enough and you only have to do once that way.

Artchee,

Its probably alot cheaper and easier to just buy the relays and replace them. I've never heard of different boxes in the same year. I know different years have different boxes (mine was actually build Oct. 98). Others who have never soldered before have successfully replaced the relays in theirs, its not very difficult. Just do a web search on how to solder, or find someon e you know to help. The relays are less the $2 each from Mouser (http://www.mouser.com/?Ne=300&handler=data.listcategory&Ntt=*nec*%2b*31000*&terms=nec+31000&crc=false&N=380&Ns=SField)

Check the link I posted above to planetisuzoo for the writeup I did on replacing mine.

Guys,

I have a 98 Rodeo and I am having the wierd wiper problem, but I dont have the intermitent wiper or alarm on my truck. I just have the 3 speed wipers and they just stop in the middle of the cyle. Sometimes when you turn it on high they start again. Do I have a simmillar circut board and if I can get the part does it just plug in?

I am kind of new here and would appreciate some help.

Yours probably has the same box, just a relay or two might not be used.

If you buy the whole box it will just plug in. If you just replace the relays the old ones will have to be unsoldered and the new ones soldered in. Others with no soldering experience at all have successfully done it.

Gizmo42,

This thread is kind of old. Is there anywhere I can still get the box or relays. I have soldering experience but the thought of lying on my back and solder getting in my eyes.........

Thanks for the info

Rob

You can still get the relays from Mouser (http://www.mouser.com/search/Refine.aspx?Ne=1447464+254016&Ntt=*551EQ131000*&Mkw=551-EQ1-31000&N=1323038&Ne%3d254016%252b1447464%26Ntt%3d551EQ122111S%26Ntk %3dMouser_Wildcards%26N%3d1323038%26RefType%3dHome =)

Click on the link it should take you right to the relays.

The whole board from the dealer is around $200 so I would try the relays first. You can just pull it out and work on it where ever you want. Its just a module, easy to remove.

Friends,

I went out to try to find the board you guys are talking about. I took the door off the glove box and to the left is the radio etc, to the middle it is all HVAC, I started to take the thing above that I thought said alarm off oops air bag, :-P, to the right I see something almost impossible to get to. Is that it? I cant seem to post the pics!

Thanks,

It is off to the right. I think there are two boxes, you want the one further up. Not as hard to get as it looks. When I put mine back in, I didn't even attach it correctly. that was a pain. I just stuck it up there. You just have to look at it and study how it is supposed to come out. Not that bad of a job.

Friends,

Well I did it. On my 98 there is only one box in there and my board is simillar to your pics but different. I had bought a cold heat thing and tried to use it , that thing is junk, I think I melted it inside. Anyway got out the old soldering iron and had a hard time getting the thing out but it finally came. The nec 31000S legs were a l:screwy: ittle different but I got them in and soldered it. It did not look pretty and I kind of made a small mess of the board. I put it back and thought it would explode but everything seemed to work. It was even a little louder which made me feel like I did it right.

I have a few questions. When I de-soldered and soldered it a little solder ened up touching some of the other contacts. I cleaned it up as much as I could. Are the connections on the inside of the board like a sandwich? If I did get some on the wrong spots how long would I know if something is screwed up. Everything seemed to work. Would I blow a fuse or would my rodeo just explode into flames? :-)

Well anyway thnaks for all the info. I hope I did it right!!!

I too tried the cold heat. I thought it was junk. I went back to a normal unit. Mine was a bit messy as well and I had the same thoughts as you. Mine still works fine though. Keep an eye on it and see if you smell anything odd when in use. I would assume it would short out if not done right. Feels good to DIY.

Freinds,

I replaced my front wiper relay on Saturday and the car ran fine, I drove it 4 times about 25 miles, total . I got up this morining to go to work and almost instantly the car started shifting hard, clunk every time it changed gears (automatic) and when I went to stop the car it slid two or three times about 2 feet from about 30 mph at a regular stop, like there was something wrong with the ABS. When I went to lunch and came home the car was running just fine. All the lights came on and off at start and had no warning lights light up

1. The board I worked on, does that have any control over the ABS and or automatic shifting?

2. I disconnected my battery when I changed the relay, could this have caused the computer to reboot so to say.

3. That damn alarm box is not the cars ECU is it??

Not sure whether i should bite the bone and by the circiut board or wait and see.
It was extremely hot today and yesterday but I have never had any problems like this before, the only thing I did was work on the board and disconnet the battery at ground?????

what kinda of codes are you getting?

I dont have a code reader and would not know where to plug it in. Can you give some advice on where to get one etc. I know I sound stupid but I have an Italian car and I have great results working on it but it is from the 70's and there are no electronics, every time I touch my Rodeo I am in trouble. I thought after the, I thought was successful repair, on Saturday I was getting some confidence. No this. I am going to Yosemite next moth so I need to get this sorted out.

Thanks,

Rob

I have been wanting to fix this problem in my '99 Rodeo for a long time. (My Rodeo was built in September 1998) I finally ordered two relays from MOUSER ELECTRONICS, Part #551-EQ1-22111S. When I got the parts and compared them to the relays on the circuit board they are slightly bigger and the pins don't exactly line up. Since my Rodeo was made early for its year model, is it possible that it has a different circuit board than later Rodeos from the 1999 model? If your circuit board looks like this and you have successfully replaced the relays please provide the part # and seller.

Also, if you have dealt with this circuit board and can point out exactly which relay is the one for the intermittent wipers that would be helpful too, thanks.

I have posted photo of everything I have related to this issue:

I missed this post, but I think you answered my question regarding is it possible for the 1999 Rodeo to have different circuit boards in them.

Thanks


Have found the needed ALARM MODULE at a "junk yard" with the same part number as I was given at the dealership Parts Dept. for a NEW one. However, the junk part is off a '99 Honda Passport - NOT an Isuzu Rodeo. Inasmuch as Isuzu manufactures the Passport for Honda, and they are IDENTICAL (except for the Honda insignia), may I presume that this part will work in both vehicles.

I ask because when I called the dealer parts dept. I was asked which MONTH in 1999 was the vehicle manufactured, as there are THREE different circuit boards on the '99 modules!!!!!!

ALSO... there's a good chance that this part off a junk vehicle DOES NOT WORK any better than the one on my vehicle. The salvage place cannot verify that the circuits and relays are in "working condition". If this part does NOT resolve my intermittent wiper (and rear wiper) problems can I insist that they take it back? They said they only "exchange", but very unlikely that they have very many of these particular circuit boards.

Thanks for any input here.
