Intermittent wiper problem

[Gizmo42]

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

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!

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..


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

[LGStrobel]

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.
