Hi, the windows have stopped working as has the door mirrors. The window switch on the front passenger side is working but that is the only one. I have checked every fuse on the car but with no difference. I have looked at some previous requests and it seems like the relay for them is done in. Could someone please tell me where the relay is located?

Thank's in advance.

Looking at the wiring diagram, there is no relay. Power comes from the battery through a 150 amp fuse to the four power feeds and through the harnesses to the door modules. Fuses involved are fuses 21 and 22, fuses 32 and 33. All 25 amp. Those power one door module each and the door modules control the locks, windows and mirrors.

It does appear that the door modules share a ground. Left side modules both ground behind the left kick panel, the right side modules ground behind the right kick panel.
I would start by looking at those grounds first.
