Intermittent wiper problem

mckpaul · 05-05-2004, 04:18 PM

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!

some are red some are grey

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.

A big thanks to 2000 Frontera and NATO308 for the research and pictiure posts.

great pic thanks for that bit of info

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!).

Letsrodeo · 12-07-2004, 09:38 PM

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,
Joe

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 to a thread where KJK swapped the relays and fixed his front. His rear stopped working.

Good luck.
