Lost power to drivers door functions - need diagram

Thanks for the help guys.
I'll try the battery disconnect thing, it's a he cheapest! Along with the extra ground.
I doubt it's the switches becaus it all failed at the same time. However, if the power goes to one switch before the others it could be a continuity problem.
I'll have to get in there with a probe on the hot side of the switches to see.
If I had a schematic I hat would help. Maybe I could stop by a dealer and get a copy.

Thanks
