Electric window on my 2003 Rendezvous

How do you know you need a regulator? Sometimes the window will pull out of the track and fall down in the door. Spread the door slot with a screw driver just enough to see down inside the door Take a bright light and carefully operate the window up and down..CAREFULLY remember if the door is off track, the track still will move up and down and could wedge and break or scratch the glass...if it isn't off the track or is..the inside door cover must be removed..to get at the mechanism...it can be done by a DYS ER but will,take some time and understanding of the system ..then some professional type adhesive to keep on track ..you can find a window place for that... Good luck

The door trim is held on with a combination of screws and push clips Once you have the trim off you will probably find that the window motor regulator is defective. I would recommend replacing the regulator and motor as an assembly.

Are you sure of the year? Didn't think that they made a 1996 Buck rendezvous

Hi,
generally the door panel has to come off. With the panel removed you can see the tracks. There is an adjustment for each track, and you can observe the action of the window in the track as you operate the window. slacken both track adjustment bolts if fitted, operate the window untill fully up, tighten each adj bolt and operate the window through the cycle. Make any further adjustments as needed. When correct install the door panel, and recheck the operation of the window.

Good luck.

It did not fall off anything
You have a broken window regulator
Remove door panel and replace whatever is broken

poss your window track is broken or off track take the door panel off to see the track to see if its still going up or down or poss bad widow regulator

I am guessing you have power windows. Happens to mine sometimes.
Slam the door a couple to few times, see if that doesn't put the window back on "track". I mentioned this to the dealership a while back and they were going to charge about $90 to pop off the interior part of the door and put it back on track. They said it "builds up dirt".
I actually also toggle the window switch a few times to see if it will move slightly and then do my door slam thing a couple to few times. I seem to get this problem when it rains.
I hope it helps.

If your power window motor is not moving up or down at all inside the door panel, you will need a new motor.
If your window is stuck and will not move, it is the motor - it is bad.
If your window falls down into the door panel, the window is off track.
Replacing a window motor is an easy fix, get another one from an auto parts store and replace it.
Good luck!

Yes. I have fixed my driver side window several times. The window went all the way down and came off the track, usually because the window automatically went all the way down. The first step was to take the interior side of the door off: (1) I unscrewed the screws around the door and pull the plastic screws out. (2) I disconnected the thin metal rod that connects the door handle to the door frame to be able to pull the interior part of the door away from the metal frame of the door. (3) I unscrewed the speaker to see where the window meets the rubber track. (4) I kept the electrical wires connected so that I could use the electric window button to lower and raise the window. (5) I lowered the window down below the rubber track and loosened the screw holding the rubber track to the door. (6) I manually adjusted the rubber track around the window glass and pressed the electric window button up slowly, making sure the glass stayed on the track. (7) I put everything back in place, screwed in the screws, etc. Be careful not to let the window go all the way down, because it seems to fall off the track at that point. Hope this helps!

We had the same problem with ours. With the Buicks the do not have a track per se, they have a cable system. Once there is an issue you will need to get the entire cable system replaced. It cost us around 150 dollars total. Hope this helps
