Windshield wipers quit working, fuses, relay, motor all good. Power to fuse, no power to motor. Washer pumps work both front and rear, and rear wiper works (all with same wiper switch). I assumed the switch was bad, but since it operates everything else, I am skeptical. Help!

It could be the switch still. Here is a guide and a wiring diagram for the wipers so you can see how the systems works:

If the switch checks out there is a central module that commands the wiper motor.

Check out the diagrams (below).

Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken
