99% of the time its not the motor. its in the switch itself on the steering wheel. get inside and shake the switch. switch it on and off fast. if that works then Great! if it still does not work, then unhook your battery for 30 minutes. after 30 minutes reconnect the battery and try it.

I agree. If you think about all the wear and tear it gets as a Turns Signal Switch, it's amazing that the Wiper switch lasts as long as it does. There are 2 fuses that operate the wiper system - one under the hood (Battery) and one under the dash (key power). Does the Washer work? High beams, turn signals and Hazard flashers too?

Replaced switch on steering wheel, it didn't change things, thats when I replaced the motor. Wipers worked fine for a few weeks, then stopped. I checked the replaced wiper motor with another new one, there is nothing wrong with it. Fuses are fine, washer works, lights work fine, hazard flashers work. Thanks for your help.
