Thanks for the info. Yes, key in run position and lockout in unlock position.
I pulled the driver's side switches. There are two connectors for the windows. It looks like one supplies power to the other window and takes power in on the other (light blue with black stripe).
Measured the continuity between the rd/lb wire on one of the connectors and the rd/lb wire in the passenger's window connector; 0.1 ohms which tells me that there is no break in the wire.
I powered the passenger's side directly from the battery and jumpered the connector for "window up" operation and the window went up and down when jumpered for "window down"; telling me that the motor and regulator assembly are working.
So, the next questions is why no power from the driver's side? There is 12v on the lb/bk but 0v on the rd/bl. So my guess is that the driver's side switch cluster is bad. I ordered another and will update post when I install it.
I am going to PM you the Power Window Wiring Diagrams from my '02 Shop Manuals & The Connector Views, as well as the Component Testing Steps for the Driver & Passenger Window Switches.
I have a couple more questions:
- When you checked for power at the passenger switch, did you use a known good ground?
- Does the passenger window work correctly from the driver side switch?
A couple of observations:
- You are correct, the Light Blue/Black wire supplies power for the windows to the Master Control Switch (Driver Switch). The Red/Light Blue wire then supplies power from the Master Control Switch to the 3 other windows switches.
- You said you had continuity between the Red/Light Blue wire at the driver switch and the Red/Light Blue wire at the passenger switch. If this is the case and you have power at the Red/Light Blue wire at the driver switch, then you have to have power at the passenger switch.
- The question is; do you have power at the Red/Light Blue wire at the driver switch? If you don't, then I would agree that the issue is with the driver switch.
- The other wires at the passenger switch have to be good since you said when you provided power to the passenger switch from the battery, the window operated properly.
- I recommend testing the switches using the Component Testing Steps I have PM'ed.
Having said all that:
I had similar electrical issues with my '02 XLT. The dome lights would stay on until the battery saver feature turned them off, the accessory delay wasn't working, the driver side puddle light didn't work, the keypad on the door would set off the alarm when I pressed it, the door ajar light would flash and beep at highway speeds, the radio would shut off as soon as I turned the key off, the alarm would beep twice when I armed it. Recently all 4 windows stopped working. Most recently the driver door lock actuator stopped working.
A lot of electrical issues can be traced back to broken/damaged wire(s) in the boot between the body and the driver's door. I found 3 broken wires and repaired them. The thin black ground wire was broken and after repairing it all was back to normal. When the windows stopped working, I repaired the thick black ground wire and the windows now work like a champ. I had to repair the pink/black wire to fix the driver door lock actuator.

Here is a great thread for checking for broken/damaged wires, thanks to
synyster for this awesome write-up:

Be sure to take your time when looking for broken/damaged wire(s). Check all the wires for breaks/damage. When you think you're done looking, look again, and again, and again. A bright flashlight can be very helpful.
Sorry for the long winded post. I hope I haven't overloaded you with information.
Good luck getting the whole thing sorted.
