Lets say you go to turn the windshield wipers on, and nothing happens. Blinkers, brights, cruise, etc. all work on the lever, but the wipers and windshield wash spray do not work. Then, an hour later you try it for kicks and giggles, and it works just fine. What would you believe the issue is? All fuses are good...and it seems as if they work just fine except when its raining out. Whether there is a problem with the water itself, or possibly because thats 99% of the time when I actually try to use them....Any ideas? Relay? Wiper motor?
Haunted car?
What vehicle is this ?? I had a 95 Chev K1500 that would do that and it turned out the factory had a recall on the circuit board and I got it replaced for free when the truck was 9 yeqrs old with 110k miles on it
Oddly enough, its a 92 Chevy K1500....
Is there a way to test the circuit board?
I kinda thought I remember you mentioning a Chev pickup before, that's why I brought it up. I don't even know where the circuit board is, since Stillwater Motors replaced it but it may be part of the wiper assembly. I don't have that truck anymore to look at it for you. Maybe call a local Chev dealer and ask if the recall program is still valid. They would know from the VIN if it had already been replaced.
what other type of "symptoms" were you experiencing? I would like to diagnose the problem (or at least try to, haha) before going to a shop or dealership. Basically with mine, everything works except the wipers and spray, and that is only sometimes that they dont work. I figured it was a relay, but I never thought about the circuit board.
It did exactly what you describe until one day they didn't work at all. Unfortunately, I was 130 miles from home in a steady rain. Not a fun drive.....
Alright, thanks Mitch. Ill get that checked out.
My 99 Suburban would do the exact thing, I believe a lot of the 90's Chev full size trucks had the circuit board issue of working intermittently, when the wipers on my 70 Z were not working because of a bad dash ground a few years ago, I was going to meet friends in No. St. Paul on a friday night and it was great outside but with a chance of rain after 10:00 pm, I decided I was going anyway but I had heard Rain-X wiped on the windshield would help in case it rained so I put some on before I left in case, It started raining at about 9:00 that night as everyone flew out of there, as I was going west on 694 it downpoured and I thought "here we go" at hwy speed I could see out my windshield better than any car with the wipers on full blast, it was almost clear veiwing out the windshield in an absolute downpour, I was amazed, try Rain-X next time!
morning to all, the wiper circuit board is under the wiper motor cover ,very easy to get at and to replace in the engine compartment on the fire wall. I have replaced several of them in my 1992 k1500. you can change them in about 20 minutes with out trouble ,the cost at napa is about 40.00 the last time a bought one . I have replaced 3 of them .good luck Joel
I dont suppose that the wiper circuit board is the same circuit board that controls the gauges in the dash?
I'm going out on a limb and saying that it probably doesn't, but if connected, it could pull the other circuit board down. You would need diagrams to see if it was a possibility.
I would check for grounds that may be affecting the overall electronics.
