Customer Question

My 2003 GMC 2500 pickup wipers won't turn off. I replaced the entire switch and it worked fine for about 5 minutes and now the wipers will not turn off again. What's next?

The module that controls the wipers is the problem, The module is located on the wiper motor and can be replaced without replacing the whole motor assembly.

Where is the wiper motor?
Expert:  MPMoore replied 7 years ago.

The wiper motor is located under the cowl, the plastic panel between the windshiled and the hood. You have to take off both wiper arms to remove the cowl panel.
