Elusive 22039684 Windshield Wiper Motor Cover


Oct 3, 2017
Summerville, South Carolina
Recently my wiper motor stopped spraying with the washer motor so I replaced the motor to no avail. The motor then seemed to act up when wiping the windshield so I replaced the motor that came without the cover and circuit board Part #22039684. The wipers operate normally even when trying to use the washer mode but no water spraying. Tried looking online to find that it has been discontinued (no surprise). Does anyone know where I can find this cover with the circuit board and would this cause the washer motor to not operate? Only thing I can think of is scouring the junk yards but there isn't any close by in South Carolina that has any G Body cars with this wiper cover.

At this point you'll have to resort to a good used one. That's pretty much what I had to do for a few of my cars. I was lucky enough to find them at the junkyard, and this was years back. New parts are NLA, and nobody seems to recondition them...as far as I know.
As for the washer function, did you check the nozzles for blockage and the hoses as well? They do commonly clog. Use a small piece of welding wire or any small gage wire. Once you determine that the lines and nozzles are free of obstruction, try priming the pump. The circuit board would affect the delay/ pulse function more so than the washer function.
I suggest putting the word out there. Someone will be able to locate one in their travels, I'm sure. Good luck!

Oriellys sent mine to one of they’re suppliers and got mine rebuilt. They couldn’t find any reference to mine on they’re compute.

You can't find them because when I lived in Summerville in the 80s I picked the j/y's clean. :) Oh wait, that was 70s parts...

Yeah, that circuit board is hard to find.

You may be able to find an electronics geek or geek shop that specializes in fixing strange electronic junk. I'm sure it's just a diode or resistor or some other cheap chit keeping it from working right.

Did you get the new washer motor in correctly? Also, there's a park switch you need to transfer over from your old wiper motor to the new one. GM/ACDelco motors are supposed to come with them installed. Don't worry, if you took in your old motor with the switch on it as a core, I think you can still buy new park switches on ebay.
