Worked like a champ. Thanks!
(Fixed!) Welp…after looking at the board I put on a week ago, I came to the conclusion that the board is junk. Some solderings either werent there/missing. Took the board back to the “parts store”, they replaced it for free after comparing new one to “old”, I installed it there in their parking lot. I used some silicone grease on perimeter of cover…whammo!! problem solved. I also ran a “ground wire” from motor-firewall as precaution. I believe this will fix the issues permanently. – DTM
94 C1500. replaced pulse board approx 1 week ago. (replaced it twice now in 3 years) fixed issue til it rained yesterday… Now, no power to the fuse for wipers. Power to the connector plug on motor. After a bit of research today on here, I ran a “lil ground” wire from the firewall to the wiper motor… still nothing when I turn on wipers on multi switch… still no power to the fuse for the wipers. (stumped and puzzled)… any help appreciated. thanks … – Dantheman
My wipers stop in the wrong position all the time, even worse, they don’t stop sometimes. is this due to the wiper module??

i have a 95 chevy and every time i put a new fuse in it and turn the key i blow a fuse any ideas?
if touching that connector makes the wipers work again then the problem is most likely a cold solder joint on that PCB, any geek with a 15 watt solder iron cold fix it in 2 minutes, thats all it was with mine in my 94 k3500 sliverado
I have a Malibu 2003 and wipers don’t stop when ON, only way to stop them is to stop the car. Any idea what’s the problem? Mario, Nova Scotia, Canada
Will do but so far I haven’t received any answers from any sources.
yeah my 1990 silverado has the long skiiny board. I can’t find one anywhere. thought about getting whole new motor.But I guess they dont come with the pulse board. so I dont know what to do.If you find out a part number for your module. let me know.I will do same if i find one. but i dont have high hopes
I have a 1989 chevy stepside C1500 and mine has all these same symptons but my board is long and skinny. Does anyone have a prts number for this style board?
Good info! Thanks
Tried to remove the old pulse board as you did. Seems some yahoo decided use insanely strong glue on the connector section to the housing. Now I have to replace the housing as well. Great video though.
2002 chev impala. one wiper works on one side, the other side jerks up about 2 inches then goes down. goes up 2 inches then down
gotta 02 ls and they wipe just fine but they will not go into park possion they park in front of my eyeballs could it still be the connector as in this vid thanks
04 Duramax Crew Cab Dually, really strange wiper problem. While operating wipers in rain, right side began to slap when it went down. As it continued, it would rise less and less until it completely quit working, all while the left side continued to work fine. Don’t know where to begin, but tearing it down today. Any thoughts?
I have a 94 gmc truck. Yes thats your problem. go to a junk yard and get one thats what I did it was about 10 bucks
do u have a yukon? i turn my wiper switch on hear noise but wipers dont move, so what do u think?
ive got an 02 impsla its had major wiper issues its not a bad motor because all setting work except when turned off they will not park in the home position they stop in front of my face any idea what the prob is i was told it was a bad motor but the motor runs just fine thankyou great vid btw
@Smith you most likely dont need a new one. Pull yours out and look for broken solder connections. Most of the time thats the problem. Resolder and reinstall. Free fix.
mine is a 1990 c1500. my wiper motor pulse board looks different and i cant find right one
Thanks for the vid.
Thanks Man, my 87 has got me stumped, but I will try the pulse board next. Appreciate the video.
another comon prob is when you turn them off they wont go to the park possition
Why would I sacrifice a simple wiper problem on a GM for every single problem under the sun with a damn Ford?
My gmc did this for months till I saw the recall of the board. Went to a junkyard got new board and no problems now
Thanks for the step by step. Very helpful.
Thanks! I’m gonna replace the board myself tomorrow so I won’t die like I almost did the other night.
i know another common problem where the wipers wont go down its a somewhat simple fix just weld a piece of metal to the old wiper stop
you can also resolder the pin connections on the board if you look close you can see there will be 3-4 that the pin is broke free and the solder around it is not making contact i did this to my girl friends jimmy and it works great and it is free!!!
do you remember what size torque srew bit you used.I dont have any and dont want to have to buy them all
my wipers on my 1990 c1500 wont turn off unless i shut car off.i just replaced steering column but it had similar probs with old column. only 2 sppeds will work and my window washer fluid wont work. would it be this be causing my probs
i just bend up those two contacts if im in a bind, all moving the whole thing does is just move em in a bit
THX MAN! it’s been driving me nuts for 6 months.
Install a ground wire for a cheap fix at the same time and GM should of done this in the first place.All you need is a short piece of wire with a wireend crimped on each side,Attach one side to the body and the other side to the wiper motor.
Do you possibly have the wrong part?
i bought a new cover and cant get the pin to line up with the slot in the blue disc. any ideas?
Did the new wiper motor not come with the circuit board?
i have a 93 corvette which the wipers crapped out. i had probed for power and determined power up to the control board. i thought the motor was bad so i replaced that to no result. Are there any other relays i am not aware of or do you think its the control cover on my vehicle as well? moving wires didnt seem to make them work, and its becoming a process. thanks
You could have a problem with the motor, connector, switch, or wiring. Check for obvious signs first, like corrosion, melted parts, or burned wires.
I have a 92 Camaro and sometimes the wipers don’t like to turn off unless I switch it from on to off. this also affects the delays. what would I have to do?
@X2N18 There is a Wiper Board Pulse Module for a 1988 “Big” Blazer. The part number is 15598496 and it is about $57.50 including shipping. But check with a dealer to get the correct part # for your application. Their site rhymes with “sock”. If they would sponsor Dave’s site I would give you a direct link. You may be able to beat that price too with a little searching online. You can always try a good wrecking yard too. GM likes to use the same part on EVERYTHING!! lol
Advance doesn’t have a circuit board & I don’t know if the board comes with the motor or not. If you find a motor & board they should be direct fit.
yeah because i found out my blazer uses a difference’s circuit board from that one u have… my s10 blazer is full size is the truck not the pick up
i try to find the same exact circuit board but no Luck the only one i see is the one u have but won’t fit mine… so it means i have to go to advance auto parts an get the whole motor with the new circuit that looks diffident? will that fit exactly or i have to mod it ?
I bought mine from Advance Auto Parts. I don’t know if you have an 88 full size Blazer, or S10 Blazer. I looked on their website & didn’t find one for either. The last time I needed one for an 88 C1500 I used to own, I got one from the dealer. It didn’t fit. When I called them back they said I had to buy the new updated motor to go with it. The motor came with a board on it, but it was for non-delay wipers. So, I had to put the new board on the new motor. This was over 10 years ago.
man you are fuckin cool thanks for all your hellp
where can i get a new 88 board for my blazer? do u have a website where i can get it ?
