SOURCE: power windows will not work

do you hear a noise coming from inside the doors? if not then the motors are shot. if so then you have an electrical short

SOURCE: power windows, sunroof, interior lights not working. Fuse?

I just saw your posting. Yes, It could be a fuse, a 10amp interior light fuse BUT... I had to replace the Central Locking Control module which toasted first... I had the 3 open door, no working lights/windows situation too...

The problem seems to be in the main cabin light which has the 3 way rocker switch. Turn this off (depress the side on the driver side of the car (US)). Check the 10 amp fuse for the interior light. If it is burnt, you are OK if its not, you need to replace the Central Locking module. ~$200 US

I still have not replaced the cabin light module where I think a short is. If I replace the fuse in question, and turn the cabin light on, it "pulses" for a few minutes and then cooks the fuse.
