rear wiper won't work. replaced with a used one and still won't work. they both made a noise like they were stuck , thumped and clunked but would not move.checking power to the motors only got power to the orange wire.
rear wiper on 1997 Oldsmobile Bravada
remember, a junk yard part is from junk. maybe you should start with a re man motor. you have power but you need controls from the switch as well.
