Question about Cars & Trucks
I would remove all door panels
Unplug & test each window motor,
powered directly to the battery, in
That way you know if all the motors work,
if all regulators work
You say you believe the motors & switches are good
No you don't & you should have tested them before you told us
Now for the switches--you will need wiring diagrams, regardless
of whether you do live voltage drop testing or ohm the switches
out of the circuits (unplugged)
You need battery voltage to all your power points at the switches
You need-- when all that is done & your still at a lose for no reason

try replacing the master switch it maybe malfunctioning due to wear.or may have shorted out by getting wet or something.since it is the primary control for all windows and power door locks.

I have had to fix three out of four windows in the past month.of my 2004 jeep grand cherokee. I went from a semi cold environment to a really hot environment. I was told by Jeep, after the third time of course, that the wires had more play in the hot environment and had shorted out because jeep did not put correct housing over the wires next to the door. If you have the same problem put electrical tape around your working electric windows so it does not happen to your good windows.

Did you check for power at the switches. Are you sure the fuses are ok. Sometimes the wires break because of opening the door. You will have to inspect the harness and maybe have to remove the door panel. Most likely its a driver door wiring issue or the fuse.
