Power Windows and Locks Behaving Badly

[nicomp]

2000 LeSabre.
All 4 power locks work from the key fob. Passenger side locks and windows work from the driver's control panel, driver's side locks and windows do not work from the driver's control panel.

Augh!

Could be bad switch, but it's complicated to diagnose, each door has it's own module. If you can access a wiring diagram it would aide in the diagnostics a great deal, you could unplug the switch to jump the individual terminals, but could cause damage if done wrong so really need the diagram to make sure you're jumping the right wires. A scanner with bi-communication may also help if you can find one. With it you can bypass the different switches and attempt to operate them from the door modules themselves and see if the windows and locks respond in that manner. Does the rear window work from the switch in the rear door?
