1993 Chrysler Town and Country windshield wipers

Have your mechanic use a grounded test light to measure the voltage on the case of the motor. If the test light lights up, the ground strap is burned open. This is a real common problem that most professionals have seen before. Just run a new ground wire from the motor to the body.

If you look at the mounting plate for the motor, you'll see the three bolts are mounted on rubber bushings to isolate vibration. They prevent a good ground connection, so one of the bolts has a brass strap under its head. That's where the bad connection develops.
