jahroy72 Posted July 2, 2022 Share Posted July 2, 2022 I have a 1972 Monte Carlo and when I turn the wiper switch on I hear a click under the hood near the wiper motor. Just one click as if a solenoid was going off. If I cycle the switch back and forth I keep getting the single click with no wiper operation. Any ideas? I kinda copy/pasted the problem description from some other guy on some other Monte site who appears to be having the same issue I am - hope he don't mind. He didn't have any response to his request so thought I would try here. Thanks. Quote Link to comment Share on other sites More sharing options...
Scott S. Posted July 3, 2022 Share Posted July 3, 2022 Time for a rebuild or replacement.... The actuating cam has probably worn out, (usually a cream coloured wheel about 1 1/2" in diameter) and isn't activating any of the wiper motor functions. Luckily it's a fairly generic part from G.M., so finding one, (a motor) should be easy enough. Just remember to keep the original works that hook to the motor, as every car has it's own geometry for operating. Quote Link to comment Share on other sites More sharing options...
Dtret Posted July 3, 2022 Share Posted July 3, 2022 If you’re replacing the wiper motor completely, make sure you get the one for depressed wipers( hidden). Quote Link to comment Share on other sites More sharing options...
jahroy72 Posted July 4, 2022 Author Share Posted July 4, 2022 Yeah, I was thinking about doing the the same thing (replace entire motor). I had a heck of a time getting the 3-contact motor connector off. When I looked at the backside of the motor after I got it off I noticed the broken resistor. I may have broken the resistor trying to get the connector loose... Has anyone replaced the resistor and/or relay in one of these motor assemblies? Can a guy still even get the parts? I did a quick internet look and didn't find anything. I'll still probably replace the whole thing but just out of curiosity may look at trying to repair this one "in my free time" (in other words may end up in a box in the garage...forever).

Dtret Posted July 4, 2022 Share Posted July 4, 2022 You can probably go to a junk yard and pull a resistor out of another car. Probably any 70’s early 80’s gm would work. Quote Link to comment Share on other sites More sharing options...
