Intermittent wiper problem

Are you sure that is the 'alarm and relay' box and not the 'anti theft and keyless entry' box?

Should have more relays in it and a peizo speaker.

My rodeo was built october '98 if you look at the first post at http://forum.planetisuzoo.com/viewtopic.php?t=5608 that is my box.

I'm not certain of the distinction you're making but the box this board came out of is labeled "DENSO ANTI THEFT & KEYLESS ENTRY"

Are you saying there's another box in there somewhere? If you are I certainly didn't see it.

My alarm box was bolted to the passenget side bulkhead up underneath where the vent is located. It had one screw and once that was removed it had a clip that when pushed up just came out even though it was a little different from the earlier pics it was very simillar. The glove box had to come out also. I have a 98 but no alarm, windows, cruise etc. My problems " brake & auto shifting" seemed to only happen once now it is back to normal, I think it was due to the unhooking of the battery nt to my crude soldering techniques!!

That is the wrong box for the wiper relays. There should be another box mounted verticaly right above the anti theft box (which should have been mounted horizontily) labeled "alarm". Its the one labeled alarm that you want, it has the wiper relays in it. The buzzer that tells you your lights are on or keys in the ignition with the door open is what they consider the alarm.

Gizmo, please take a look at this photo and confirm that the box you are speaking of is the "red" box, correct?

I thinks thats it mine was black thogh the one screw held it in and it pushed up around an ince and came out!

Yep it should be the red one (mine is white). It should have the word "alarm" on it. It may be possible that someone switched their places at some time so make sure you get the one labeled alarm. Looks to be it though with the white plug.

Thanks

:rofl: Happy to report that I finally got the opportunity to complete this project, and it was a success!

Thanks for everyone's help.

Congrats! :smokin:

Knew you could do it, just takes some patience. I prefer to use solder wick instead of a solder sucker, it works better for removing all the solder.

It's unfortunate that i found my way back to this post... i will tell you all right now (in case you haven't figured it out) that if you're having problems with the front wipers, you might as well go ahead and replace the rear relays as well. That's why i am back- i fixed the problem with my front wipers (thanks to the great information here on this post) and then a year later, my rear wipers are in a stuck position.

It's sucks that Isuzu used such crappy parts and we all end up having to buy replacement relays. I'll probably never buy another car from them again (it's the little things that makes the difference, you know?).

Oh well, time to open up the glove compartment again...

Thats why I replaced all 3 at the same time. They're cheap enough its not a big deal to do all of them. I know I wont need to go back into mine again now for quite a while if ever. Still beats buying a whole new box.

Recently changed all three on mine too.

i haven't had to replace a relay yet; 1992 isuzu trooper. parts go. 7 years, that's not bad; the hassle was you didn't really know how to diagnose it. now you do. be proud.:smokin:

I'll probably never buy another car from them again (it's the little things that makes the difference, you know?).
yeah, like not having any dealers. . .:wink:


...or product...:wink: :wink:

Has anyone found a place to buy the fujitsu quiet relays yet? or a way to to quiet down the NEC ones?

my wipers have had this problem for over a year now and the wifes tired of it.

You can get the fujitsu ones if you want to buy 1000 of them :screwy:

From what others have said the other ones arent all that loud once its in place behind the dash. You can try wrapping some rubber tape around them before soldering into place, should help quite them down a bit. The original fujitsus are actually a smaller relay wrapped in rubber tape then stuffed into the larger case.

Hi All,

I'm new here but have been following this thread with considerable interest because my 1999 Rodeo has the same intermittent wiper problems. The front and rear work pretty much how and when they please. To fix this I ordered three of the NEC EQ1-31000S relays from Mouser and installed them in my board. Now the fronts work great, but the rear doesn't work at all. When I push the button, the relay clicks but the wiper doesn't move. I even swapped the RY3 and RY4 to see if that had any affect. Nothing. Both wiring connectors are solidly connected to the board and I even tried wiggling the connectors. Nothing. Does anyone have any ideas? This thing is driving me crazy.

Someone plz answer this Im having the same problem with mine. I'm about ready to sell this car and just start riding a bike to work. I hate waiting for the rear windshield to defrost.

With a new relay installed it can only be a few things that I can think of.

1. bad solder joint on the relay (can happen to anyone)
2. broken wire. most likely where the wiring goes into the tail gate.
3. switch for the tailgate that turns on the interior lights not working properly
4. bad wiper motor.

I have a 1999 Amigo that has been having wiper problems both front and rear. I found a fujitsu distributor that will sell the relays (FTR-P1CN012N) in quantities of 25 or more. If I was to order 25 of them would anybody be interested in purchasing the ones I don't use for $10 each plus shipping? Let me know and if enough people are interested I will get them on order.

Also, here is a picture of my circuit board. It came out of a green box and has a slightly different arrangement than the others that have been pictured in this topic. Can anyone help me identify what each realy controls? Thanks for the help!

Can anyone help me identify what each realy controls? Thanks for the help! The horizontal one on the lower right just above the connector socket controls intermittent on front wipers. I didn't replace the others, but my guess is the one just to the left controls the rear wiper, upper left relay is washer pump & upper right is horn relay. But be advised I'm only guessing on those last 3 since the only one I replaced was front wiper inter. control relay! The board out of an '01 Passport looks just like that!

If you'd asked 6 months ago, I'd have joined you. Unfortunately, I've long since purchased an NEC relay (551-EQ1-31000S) for $2 or so from Mouser & fixed my intermittent front wiper problem. It is quite a bit noiser than the OEM relay. It bugs the Boss (wife) when she's sitting at a light, but you can't hear it at road speed. I ended up wrapping the entire alarm box in foam & that nearly eliminated the clicking. Whatta pain.

Thank you all for this thread -- I'm stuck with the same "front wipers won't park" issue on my 1998 Honda Passport and I've grown tired of trying to time it right and stop them in the right place.

After reading through all of the posts, I'm still not sure where to find the circuit board to remove/replace the relay that folks have ordered from mouser.com.

I looked to the right of the inside of the glove box and I see the ABS box (which I'm staying away from). I took off the small side panel under the glove box and found a small black box (relay?) at the bottom, then a small white box above it. I unplugged the male/female of this box and my wipers stopped moving altogether, so I think that's it. But then I don't see where this circuit board is that people have posted a picture of. Is it inside part of this white box? Are the parts folks have order from mouser tiny, like 1/8 of an inch?

I've posted a picture of the white box -- can anyone tell me if that's right or if I should be elsewhere?

Forgive my ignorance here - this is my first time cracking open an auto! Thanks...

Its not behind the kick panel its behind the dash. Take the glove box door off, look to the right and slightly up behind the dash. You should see boxes that look like this pic from rodeovyn..
http://files.automotiveforums.com/gallery/watermark.php?file=/500/380286I3010331b-med.jpg

The black one with green plug in the pic that sits horizontally is the anti theft and keyless entry box, the red one with white plug above it (top right of pic) mounted vertically is the one you want. Its labled "alarm and relay". They are different colors so yours might not be red. The board slides out of the plastic box once you get the box out.

Its a little more difficult then it looks but just need to remove the 1 screw under it then slide the box up and it will come out.

Thanks for leading me away from the boxes in the kick panel!

Mine doesn't seem to look like that picture, though. There's a white box with Isuzu ABS on it, possibly the two relays are inside there? I was hoping that I'd take off the glove box again and see that exact look, but no luck. I don't have keyless entry/anti-theft in my Passport, maybe they lay it all out differently for vehicles without those features.

I'm close to giving in and hitting up a repair shop, but I don't want to fail at this!

LG, yes, it's the white box. Remove it (pain in the a**), open it, and you will see the ciruit board.

Thanks again, all. I removed the "Alarm Control Unit" and have two relays on the way in the mail to replace my intermittant front wipers. Exciting times...

The whole Alarm Control Unit (part 8-97124-978-1, btw) runs $233, by the way. So replacing the one relay in there is just a little cheaper! I priced it out in case I ruin the board trying to solder better than my 4-H electric light board from 25 years ago. The pressure is on to do it right...

Where did you order the relays from? My rear wipers have stopped working now :(

I "met" a guy that had done this same thing by finding him on a Google search for the intermittant wiper problem (same way I found this board) and he had two extra. Assuming I don't ruin one I'll have an extra I can mail your way...I think I'll be doing the soldering early next week (he was mailing them yesterday). I'll let ya know...

My wipers are resting nicely in their "down" position for the first time in about 3 years. It worked - thanks to everyone for their help in getting me through my first electrical automotive fix since installing an Alpine stereo and speakers in my old Malibu.

If you're reading this thread and thinking "maybe I should just drop the $233 and buy the whole thing from Honda/Isuzu", don't do it. I spent $11 on a desoldering iron and got some free relays from a guy that had leftovers and I'm a novice with electrical experience from 4-H about 20 years ago.

Did you use all your relays? If not I'd pay ya for one.

Tom.

Another satisfied customer! Thanks to all for the AWESOME information!

Thanks for all of the info, just swapped out my relays and reinstalled. FYI I got my relays from mouser from this link: http://www.mouser.com/search/ProductDetail.aspx?R=EQ1-31000Svirtualkey55100000virtualkey551-EQ1-31000S

they were in stock (assumung you want less than 5000 of them.) I ordered [email protected] ea and shipping was around $5 regardless of whether you order 1 or 10. Shipping was quick, and they fit like a glove. A note though, they are louder than factory. I found a solution that quieted them up: I cut several strips of Dynamat (essentially self adhesive tar paper for sound deadening purposes, especially prevalent in car audio). you only need a few square inches of the stuff, and it is typically sold by the square foot, so I went to my local car stereo shop and they were happy to give me a scrap that was laying around. after sticking some onto the relays themselves I lined the plastic box with it too, and the clicking is now unnoticeable.

My front wipers work on the intermittant setting and park themselves for the first time since I owned my '00 Rodeo, but my rear wiper is still unresponsive. I took my box back out and resoldered a spare relay into each position only to have the same result....Any thoughts on where to go next?

Could be a bad fuse, bad motor, or broken wire (most likely where it goes into the tail gate) or bad switch.

You will have to start tracing power and ground through the circuit and see where you lose it. Not a fun task but not too bad.

Glad at least part of it worked out for you though.

ere is my contribution about this problem:

I bought a used Rodeo Isuzu 2002 last year (2006). After one year, Appears the same wiper problem as above mentioned: front wiper do not park in correct position, intermittent not working, has to manually park the wiper by switching them off at the right place. Not life threatening but boring :)

Bringing the car to the mechanics he suggested to replace the wiper switch (come altogether with light switch) which cost $200 for the piece plus labor. I can not afford that and, even if I am far from a mechanics, was pretty sure it has nothing to do with that simple switch. I so decide to review several forum and though at first it was the park switch (or position indicator) next to the wiper motor that was faulty. I was about to open it when I found this thread. I did what you guys recommend and fix the problem for less than $10. Thanks a lot.

However, I found some parts tricky so want to emphasize the thread:

* Alarm box location: remove the glove box by unscrewing the two screws by the glove box hinge. The box is then on the far right side (left steering wheel model) and is about 5 x4x1 inches in size. You don't see the electronic board but the plastic box. It is written alarm on it as well as ABS but ABS just refers to the thermoplastic material (acrylonitril butadiene styrene) and NOT anti-lock braking system! The box is a little bit tricky to pull out (and even more trick to put back in place) since it is hang by a single screw and a hook.

* Solder: the original solder used for connecting the relays melts at higher temperature than usual commercial solder. You need to have a soldering iron that can reach that temperature. Most irons with adjustable temperature can, most fixed temperature irons can not.

* Mouser doesn't sell the original relay by piece; you have to buy 80 of those. Even at $3.60 a piece it is kind of expensive to buy 80 of them (December 2007). So I bought the other relays recommended in this forum: 551-EQ1-31000S which is a little bit noisier (who care) but can be purchased by piece at even a lower price: $1.68. I bought 3 of those to replace all the board relays. Unfortunately the central leg of those relays is larger than the original one and need to be put in place by forcing. Be careful to not brake that leg (I personally bend one but it is still working). Be firm but gentle.

*Putting the alarm box back in place is a nightmare. I spend nearly 20 minutes trying and didn't succeed to put the hook correctly in place. If anyone has some trick please let say it. However, it hold with the screw and don't vibrate.

Last word: I am extremely happy to have fixed that problem myself and am very grateful to this forum and contributors. Thanks a lot. No my wife believes I am a mechanics :)

Sincerely,

It worked for me as well! I have to agree with the above post that it is difficult to both remove and replace the module. I did not replace it back in the same spot in case I ever have to do it again!

I think that Greenwich Electronics sells individual direct replacement relays (part # AR7-012-CQ6S). They have a direct replacement catalog that lists the original Fujitsu relay as the part mentioned here. The replacement is a quiet relay and should not loud click like the NEC many people substitute the Fujitsu with. I'm going to place an order through them and post how they perform/fit.

Here's the replacement guide:

I have problem. My rear wiper works all time when I turn my key. I replaced both dash switches, relays and ....:banghead: no changes-still works. Whats wrong?

Does anyone have any relays left they want to part with? Attempts with Mouser and Fujitsu quotes only offer 80 at a time. Must the border thing or something (Canada). Would prefer the one that fits without too much greif. I am capable, but Murphy follows me everywhere I go.

Hello monkeymantn,
Have you received your Greenwich relays yet and if so are you pleased ?
Thanks to ALL that have posted on this subject as I am very glad to have found this forum. My wipers have not worked for over a year (intermittent and rear).

I have a 1995 Rodeo and i took out the glove box, but didnt see the boxes that were described. does anyone know where the alarm module is in a 1995?

This message is about +98 Rodeo's.

Relays are available from RS, (Allied Electronics in USA).
RS part no: 627-9151 (Australia), 399-8225 (UK), 821-1038 (USA) cost in Australia is $4.40 inclusive of GST. RS have no minimum order. The relay is OMRON G5LE-1 DC12, and is direct replacement for original (fits without modification & works perfectly). The G5LE-14 DC12 is a fully sealed version and can also be used

Also, glovebox doesn't need to be removed - just squeeze the sides until the stop lugs release from their grooves. The box then drops open fully for easy access to the alarm relay unit.

I wish I'd discovered this thread 3 years ago!

Jules

Thanks for the info. Always good to find more options for replacement. I'm going to post that info in the planetisuzoo write up that I did as well.

As for the glove box, I do it the same way. I just say to remove it cuz its easier then explaining it lol.

2001 Rodeo Sport
Same problem same fix - excellent advice.
I have 2 extra relays from a donor board/module, so email if you need one.

Desoldering the relay is a real pain. I have no real experience with soldering either so that doesn't help. I am using the desoldering braid but relay wont budge. Any tips? Did you just use the braid on one connector at a time and
then pull off the relay. Seems improbable cause some solder kind of always stays. Do you pull on the relay while you desolder? Stuck with desoldering :crying:

I use the braid on all the pins of the relay to get as much solder off as possible. Then while carefully prying up on the relay, put the soldering tip on one pin of the relay at a time to melt anything holding it in place. Just go a little at a time and keep working around in a circle, eventually it will come all the way out. You just dont want to stay on one pin too long and burn the board or pry too much and break it.

That's the ticket - keeping working around :runaround: the relay. I actually worked two posts first to raise it a couple of mm's on one side then worked around in a circle. A solder sucker comes in quite handy .

Well I have done it all. Replaced all three relays on the alarm board and the rear wiper is still not working. :banghead: I just removed it and put + and - from the battery to the terminals on the motor and it doesn't work. I even disassembled the gearing to isolate the motor (incase there was a binding gear or something).
I would assume that since I did this and the motor didn't work, the motor must be fried, yes???
I tried pulling it all apart and checking the brushes etc. Even tried cleaning the brushes and the parts they contact, but to no avail.
When I activate the dash switch it actiones the relay, so I would assume that the switch is fine, too.:runaround:
Thoughts from the studio audience?

OK, rear wiper was not working so I replaced all three relays with no luck... The relay clicks but nothing else. I went to the jaunk yard and picked up another board and now the wiper works but the dome light doesn't. Any ideas?

Thanks

any one? Please...

any one? Please...
I never heard of the dome light being connected with the wipers at all. Are you sure it is not something simple such as the bulb or a fuse?

Its not connected to the wipers but it is controlled within that same alarm circut board. Anyone have a wire diagram of the board?

any one have the diagram for this board?

thanks for the info guys, the dealership wanted over $400 dollars to replace the alarm box. they did tell me that if you just get a new or used device (alarm box) and installed it ,it would crash and would be lost immediatly. I was told that if the module is to be replaced it needs to be hooked up to a tech 2 machine and all of its programing downloaded then that data is uploaded to the new module, because all of the data on the module is your vehicle specific. It contains your vin and other info specific to this one particular vehicle. It seems replacing a faulty relay circumvents data loss or distortion and very cheaply. I just knew their was a few folks around that were smart enough to not get ripped-off by a dealership. thanks for the info guys you saved me $400 bucks.

does any body know what the minimum or maximum amperage is for the intermitent wiper relay i know it's 12 volts but what is the min amps. p.s i can get loads of relays that will fit its just getting the amps right

Okay I have the intermittent wiper problem on a 99 Passport. Intermittent does not work, but low and high do. I ordered replacement relays from mouser, got the old relay off (the one in the picture) put on the new one, buttoned it back up and plugged the board back in. However, now what I get is the wipers working at all settings, even off. Still no intermittent but the wipers do run in low at that setting. What could I have done wrong, messed up the removal/installation of the relay or what? I have unplugged the board for now since the wipers do work in low and high without the board but I certainly can't have them running all the time. Any help appreciated.

Busy Mechanic:
Should be a minimum 20 amps, 30 amps would be better.

rburdette:
You might have gotten some solder between 2 of the pins shorting them together. Mine has devoloped a problem where if I use the rear washer the relay will stick and wiper will keep going until I hit a big enough bump to unstick it. Works fine with just the wiper function though. One of these days I need to figure out which of the 2 rear relays are for washer function and replace it.

I have a 2002 Rodeo Sport that has the rear wiper problem not parking back to it's home after you turn it off. I have read the threads about the relay replacements and at one point I think that Marcus had stated using the NEC 551-EQ1-22111S Relays. But then I see a lot of people using the 31000S Relays. Is there much of a difference between the two cause I ordered the 22111S's from Mouser? Thanks.
