Rear window defroster and the intermittent wipers are working

Hello,

From what I can see no they don't. They do not share a common ground, which can be just as, if not more, important. 75% of all vehicle problems are in the grounds of the affected circuits. I have included wiring diagrams for both the windshield wiper and the rear window defogger circuits in the diagrams down below. Please get back to us with what you find out, or if you have any other questions, please do not hesitate to ask.

Thanks,
Alex
