Wiper motor problem

My windshield wiper motor has been acting up, and when the wipers stop working, I can wiggle the wiring harness going into the pulse module, and they start going again. Has anyone changed one or both? I am not sure if replacing just the pulse module is the fix, or if I need to replace both.

Any ideas, or things to check???

Thanks,

Call your dealer...not sure of your year model, but Chevy DOES have a recall for the windshield wiper motor.

The recall number is 03023 "Windshield Wiper Motor Failure"

Hope this helps...
