..

had the same problem, everything worked but the driver side window and door lock, I had it diagnosed at Chevy dealership and the problem was the driver door control module. the price from Chevy was around $ 775. I found the part new on eBay for $150 and had Chevy install it for $98. hope this helps

Beings as everything that stopped working is on the passenger side, I'd think some wiring got disconnected or broken.

Sounds like the passenger side window motor has a bad connection or is shorted internally. There should be a motor plug in connector for the passenger side, as they are multiprong, it is possible for one part to work and the other not to work.

Unplug the wiring connector for the lock/motor and use a tester to see if the signal is consistent from the buttons you are using. One thing that is a little of a disadvantage is having the door open to work on the wires and closed for real world operation. A broken wire may wiggle to work when the doorjam is open and fail when the door is closed.

When the window seals start leaking on the outside glass, the rain can drip onto the motor. Also cracked solder is a common failure when motors go bad.

It could be a short in the harness between the door and the body.
Or it could be a problem with the switch in the door, but I doubt it.
You would need to get a wiring diagram and a meter or test light and find out which wires are hot and which are not to troubleshoot it.

check the window lock switch on the drivers panel, if its gone bad, the other windows will not work,,

the lock solenoid is worn out

It does sound like you have a short in the master switch on the drivers side. If the passengers switch does not work, check the left master switch and the window lock switch.

Yes you can do this yourself BUT make sure you get the plastic clips to the lock rods before you order. That is what is probably wrong with the door handle.

If all the other windows work when the passenger window won't move (during the 5 min period), then the passenger side motor is bad. If the motor pulls too much amperage, the circuit breaker that is built into the motor will trip, until it cools down.
