Hi,
The wiper motor on my 85 Chevy Caprice makes a squealing sound on "High", and once I even saw smoke coming from it, when on the "High" setting. The wipers move more slowly than usual also. Is this what happens when a wiper motor has gone bad ?
Is there some way to test it to verify the motor is bad, as opposed to just the circuit borad going bad? I just had to put in a new circuit board (it's in the washer pump) and I don't want to fry this one during my testing. Could a bad motor be causing the circuit board to go bad too?
Thanks
