Hello,
I purchased a rebuilt electric
wiper motor for my 55.2 Chevy truck. It only has one brown wire. Should it have a ground wire or is the body of the motor grounded when bolted in? I sanded off all paint where it mounts and connected the "wiper motor" wire (aftermarket wiring harness) and switched the motor on and nothing happened. Any ideas? I get a little spark when I connect the power wire if that means anything.
