Here?s what?s happening I have this relay fuse that kept blowing and my mechanic put this weird huge silver fuse in and it will click loudly and then the windows and heater won?t work. and it blew this fuse under my hood and after that the car wouldn?t start so replaced it and it started and I took the relay fuse out so it wouldn?t blow it again but the windows and heater don?t work. And my mechanic asked me if I had a wiring diagram for it and I looked in the manual and there was none so I told him I would look on the internet.
