Everytime I have disconnected the battery the rear wiper and defroster stops working. I mentioned it to the dealer last inspection and it was fixed when I got it back. It happened again and this time the dealer said there was a back window issue. The back window was " off track and needed to be re-aligned" and that would solve it. I said that was crap and it had to be a fuse that i can't find. Anyway it got fixed. I just replaced my battery and it happened again. I'm convinced its a fuse or something simple. Does anyone know what it could be so i don't get raped at the dealership again. Thanks!!
