I just had this problem, happens when too much water goes in the drainage bungs on the driver side (the wiper motor sits right on top). when too much water gets in, the motor gets soaked, and fries . there's a few threads here on how to bypass the bungs (just cut the openings larger)....I'm waiting for my new motor and assembly to arrive
