Thanks for the links to previous posts and different methods to try before sending the motor out to be rebuilt.
I will try these before deciding whether to rebuild or replace with an electric motor.
One more question, does anyone have a suggestion of how to bench test the vacuum wiper motor? Obviously I need a vacuum source to test the motor. Since the wiper motor is out of the truck, and the truck is packed away for the winter, I can not use that. Does anyone have any suggestions how I can get the recommended 21 inches of vacuum need to run the motor?
