How to replace power window regulator on a Buick Rendezvous?

  • well... the window won't go up. I believe the clips are still good as the window is pretty sturdy (no wobbliness to it).

    But, I need help in replacing the motor/regulator. I have the insides of the door exposed, looking at black "framing" inside door (as seen in another posters pictures earlier in thread).

    Do I need to take this whole thing out? Do I need to get the window in the up position? How do I do these things?

    Please help! LOL. Not a "gearhead" by any means... which is unfortunate.

    Thanks to all in advance.
  • Thanks to everyone who posted here. I wanted to let any Aztek owners that find this thread by googling know that the same clips are used on Azteks, and the procedure is exactly the same. There isn't a similar thread in the Aztek forum.

    The newer, better clip part numbers are 1593-8039 and 1593-8040. You can tell the difference in that the new ones use black plastic instead of white. 36 and 31 bucks full price. The buick dealer I called wanted 38 and 35, so I called my old Pontiac dealer, (now GMC), and got them cheaper. Took them 1 day to get them in from warehouse.
  • Any one still wanting to know if these front clips will work on the back doors??

    The answer is YES,,, I just finished installing two on a passenger rear door>>>>>

    Thanks for confiming that. My dealer gave me the same answer and wanted $35 each for the 2 clips. GMpartsdirect.com has them for $19 each.

    Dorman aftermarket regulators for the front are at Federated auto parts store for $90 for the whole assembly.
  • Just finished doing this job on the front passenger window. Ordered the parts from gmpartsdirect.com. New parts are made from the same thermoplastic - polyoxymethylene aka Delrin. Part has been redesigned with more, thicker reinforcing ribs. Should last a lot longer.

    To remove the door panel without tools, start by prying at the triangular panel that covers the side mirror access hole / contains tweeter speaker. Once it is pried away, you should be able to pop out the door panel one pin at a time without a screwdriver. Before taking prying off from the last couple of pins, get a helper to hold the panel by the door handle - it's awkward for one person. Be very careful with the window and lock switches - they are delicate. While trying to disconnect the window switch, I actually pulled it apart. I would recommend getting on the ground on your back and using a screwdriver to release the barb socket. The door switch can be popped out intact, but you will likely break one of the retaining tabs in the door panel socket. Once again, release the barb socket with a screwdriver.

    The pictures in post 36 were really useful. The clip on the outer rail is easy. The clip on the inner rail - the side closest to door hinge was harder. I ended up removing the door speaker - the magnet will hold it to the door - no need to disconnect. Then, remove the two bottom screws which hold the rail and motor in place. You should then be able to move the rail to a position where there is enough room to swing the clip over the rail and lock to the barrel.

    I'd like to plug a flashlight that I bought recently and used during this job - gorillatorch. Extremely small, bright, bendable, and rare-earth magnets in the feet.

    Thanks to everyone that has posted before - you made this job easy!
  • I just replaced the clips on the left front window of my '02 Rendezvous. Then when I tested it, it was making a loud noise like it was catching on something. I noticed the cable that goes on the wheels/pulleys keeps coming off the track because it is loose. Does anyone know how I can fix it?
  • Those part numbers do not match. Those part numbers show metal clips. The ones I have are like those in the how-to pictures - they are plastic. Do you have another part number?
  • I am a 64 yr. old granny and with your help I fixed my own window regulator :shades: . I'm on a fixed income so this really helped. If I can do it, anyone can. I'd like to mention that the part #s have been changed from 15286776 to 15938039 and 15286777 to 15938040. Thank you so much for your pictures and posts.
  • Well I got my window clip parts in the mail after about 10 days.
    Looked at both parts and found the black clips to be broken where they fit over the metal nubs that hold them in correct position horizontally in the assembly. Looks like the black plastic pieces were just shoved on all the way they could go resulting in the breaks.
    I looked at the existing clips to see how they were supposed to be.
    Planning to ask for refund and then get the parts locally unless they will overnight new ones to me.

    I stock quite a few clips and stumbled over this thread (trying to get some help for a customer with Buick Roadmaster).

    Noticed that the clips discussed here resemble some I have in stock.

    Does anybody have a good picture of the clips?

    Are they similar to those below? If so, which are needed?

    If there is any chance they might fit, I would provide a 'guniea' pig with a pair (against the promise to provide a DIY write up/photos to post up here).
