I have a 2000 gmc 1500. The switch on the passenger side door does not operate the window, up or down. Neither does the drivers side. But you can hear the relay click in the switch. This has been an on...

The passenger side is powered thru the driver's switch, so I would start with checking for power and ground at the driver's switch.
Could be the master switch or a problem in the harness between the driver's door and the cab. There may also be a relay for the windows in the engine compartment.

Passenger window will not go down

Its either the switch, or motor. The easiest way to test the switch
is to use the driver's switch to operate the window.If it allows the window to go down then simlpy replace the switch on the passenger side . If it doesn't then its the motor.

If you think its the regulator well,........ then it would effect movement in both directions and it wouldn't hold window up all the way.

2003 GMC Sierra - intermittent behaviour on driver side power window. Passenger side and door locks work fine. Likely in the DDM module or motor itself ? Have disconnected and reconnected the connector...

I suggest replacing the switch on the passenger side. Chances are the switch is faulty by a back connection inside - switch is wore out - if it works every now and then.

Let me know if you need further assistance.

2000 gmc sierra, blower motoronly works on #4,5 is it the switch assembly?

chances are the switch is fine, and its the blower motor resistor. this is a small circuit board inserted in the airbox around the fan area, under the dash on the passenger side, held in by two 7/32" head screws. it is available at any parts store. very common problem.

2000 GMC Jimmy SLE driver's power window

The same thing happened to my 1999 JMC Jimmy recently. I believe the problem is that your power window motor has most likely gone out or is starting to go out. The motor will need replaced. They are pretty expensive new. I went to a junkyard and got one for around 15 dollars. When mine went bad, I had rolled my window down about three or four inches and it stuck there. I took my door panel off and tapped on the motor while holding up on the window switch and got it to go up after a few minutes. I am replacing my motor today, I'll leave an update here about the outcome when I finish the job. I hope this information helps you.
