Power window problem

I have a 2002 GMC Sierra 2500HD. For some reasom my passenger power window will not operate. It has always worked with any signs of problems. I can hear a click in behind the door panel when I hit the button. The driver's side works fine. Any thoughts on what I need to check?

Thanks,

Does the window go down from the drivers master switch? Or did you not think to test it that way? If so, then its the switch, if not its probably the motor.

PS-Is there a lock out feature on your truck that prevents the passengers from opening the windows? Will be a switch on the drivers door console. My 2004 SLT had one, once engaged, the windows would not work except from the drivers seat. Safety to prevent kids from hurting themselves by closing a window and trapping someone with it.

The lock out feature is on crew cabs. I have an extended cab SLT. And yes, I did try to open it from both Driver and passenger switches.

Mine came like that when I bought it used, google GMC window regulator and get a rebuilt. Most companies offer two qualities, go high if your keeping the truck.
It was a really easy install, 1 hour for a beginner.

One thing you could do to test the motor, though some will disagree, is to smack the door. Its simple, if the motor brushes are worn, try holding the button on the passenger side in the down position. While holding the button, firmly smack the door around the bottom of the arm rest area with the palm of your hand or the side of your fist (hard but not hard enough to break the panel) If the window goes down, you will eventually need a new motor, but it can probably wait until spring.

Totally agreed.... you could also take it one step further if you get no results from the above technique. By removing the door panel-- remove the switch from the door by prying it up on the side and then lifting it out and unplugging it. Remove the 7mm head screw that is now revealed. Remove the bezel around the inside door handle by prying it up and out from the back. Remove the "shark fin" triangle shaped plastic piece at the front corner just above the door panel by prying it out-- it's held in place with metal retaining clips. Pry out the lock lever from the door panel. Remove the 7mm head screw under the armrest area.

The door panel is removed by lifting it up-- do not pull out on it, or you will break it. Once removed, disconnect the courtesy lamp bulb by pulling it out of the lens at the rear.

Now, by reconnecting the window switch and while attempting to operate the window same as described in the post above, tap on the silver can of the electric motor with a hammer --not too hard. If you verify the window works after that, then it is indeed the motor that is failing. The best way to deal with it is to replace the whole regulator with motor.
