GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hello, my name is***** problem usually is the wiper motor/module but since that has been replaced and didn't help that leaves possible problems as the wiper switch or body control module. The wiper switch sends signal to the body control module then the body control modules activates relays which control the wiper motor/module. Next step is to unplug wiper switch to see if problem stops, if so replace. If not then replace the body control module. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
The relays are fuse controlled but the body control module activates the relays and the body control module gets signal from switch. Here is a wire diagram to help show you how system works. Let me know if you have more questions, thanks.
No problem, keep me updated. Thanks again and have a good night.
