Your drivers side switch is the master switch for the entire vehicle. The wires that run through the door jam of the driver's side also run to the rest of the doors.

Some times these wires get broken or their insulation frays and develops a short circuit.

If you're handy with a test light, you could peel back the rubber boot that protects the wires in your driver door jam. Probe each wire that's connected to the master door/window switches for the other doors. You'll find that one or more of them have breaks in the wiring.

It's easy to fix once you find the bad wires.

If I've helped you, please vote for me, as I depend on this to pay my bills. Thanx, ernest.
