Passenger power window doesn't work. Doesn't work from the driver's door panel or the passenger door panel.

Did work, well, from the driver's door. Not from the passenger door.

All of a sudden, warm outdoors, the driver and / or passenger window switch doesn't work.

To test the switch, what wires do I need to test or jump? I took the panel off the passenger door. Geeze that's a lot of wiring!

A quick non invasive method, turn the truck on (don't start) so your volt gauge on the dash turns on. Press the window button, if the voltage drops but the window doesn't move its usually not the switch.

What year is your truck?

Truck is a 1990. I'll try your method today.

If switch, does the door panel have to be removed to replace switches?

Not if its like mine. I have a 92 though. Mine has one screw holding the switch panel, take that out then unplug it. That's it on mine.
