Intermittent wiper problem

[Gizmo42]

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

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

I am about as bad of a solderer as there is and I did it. It doesn't look pretty, but it works great. It tooik me a while to do it, but I got it done. Even for a novice, this is a simple job. Just a bit time consuming.

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.

Thanks,

Rob

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

You can still get the relays from Mouser

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 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?????

Rob

[amigo-2k]

what kinda of codes are you getting?

[robertgarven]

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:

(1999 Isuzu Rodeo, manufactured September 1998)

[rodeovyn]

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

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.
