Anyone have a solution, to this problem. My rear window defrost will not work,along with the rear window wiper. I checked fuses and there good. I dont now if 30amp relay is bad . Any help would be awesome.

 

Most likely one of two things. Either you don't have the rear window fully up or you recently disconnected the battery, and the controller needs to be reset. Try lowering then raising the window once first. If it wasn't fully raised, that should fix it. If you have disconnected the battery recently, they I believe you will have to fully lower and raise the window several times to 'reprogram' it. If that was the problem, you may also have to cycle the sunroof open and closed several time also (if you have one).

A big Thank You from me as well. I had the exact same issue occur yesterday after disconnecting the battery. I disconnected the battery with the truck running to test my altenator. Funny that the truck kept all other configurations except that one..

 

Thanks from me also. I was banging my head on trying to figure this out.
