2001 Sierra. My driver side window stopped

Fuses? Frayed wiring?

The odds of both switches going bad at the same time is high, remove the door panel and tap on the window motor with a hammer, while trying the switches. I may have jammed up. Ground a test light and check the motor connection, while trying the switch, power will show on either side depending on if it turning up or down

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

The most likely culprit is your driver's door control module... it's built into the driver's window switches. Double-check all your fuses before replacing any parts.

Visit the on-line store, known as reliable-store, they have the repair manuals. I'm sure you will get the solution of your problem.

You are probably looking at a regulator or motor.

drivers window works with help, it pops and grits like glass rubbing steel. Took glass lose from carrier glass works free, but the cables make noise and move very slow befor kicking braker.

I removed all 3 switches from driver and passenger door, which is really easy with a flat head screw driver. took them completely apart, very carefully, with a small screwdriver out of a christmas cracker. put them back together again and 2 switches started working, so I put 1 in the drivers side and 1 in the passengers side so now my drivers door window opens and I lean over to open the passenger door. cool, no money spent...yet ;o)

if they only stoped working on the passengers side I would check the wirring going into passengers side door for a broken wire, or right at the passengers side kick panel.

you should check the wire harness that goes from the door to the truck there must be a bad conection near by there somewhere in the harness hope this could help you.
