None of the windows work from main switch or from their own switch, neither mirror moves.
Turn signals work
Sunroof works
Radio works
Lights work
Any ideas?

Hi,

Sorry for the delay. I just saw this now. As far as the windows and mirrors, there could be an issue related to the footwell module or the junction box itself.

If you look at the pics below, I attached the wiring schematics for the circuit. First, check the fuses I highlighted in the pic. In addition to checking fuses, confirm there is power to and from them. Here is a link you may find helpful:

Let me know what you find.

Joe

See pics below. Note: I had to cut the schematics in half to make them readable for you. I did overlap them so you can follow from one to the next.

No fuse in 86, put one in there and there is power, no change though, a place for a small 5amp fuse.
No fuse in 84, put one in there but the probe only shows 0. Online diagram shows it as 30amp.
41 is good
81 is good

These diagrams say wires to window motors, am I not supposed to check wires to the switches first instead if removing all door panels?

This is why, I guess. Felt something shaking inside it.

Hi,

I just saw your replies now. And it certainly appears you found the problem. Something shorted. Are you able to get a replacement part?
