How to replace power window regulator on a Buick Rendezvous?



  • Hi,

    Great help on this issue. I wish I would have found this about a week ago, but I still have a problem. I got the new clips installed, but the cable going to the bottom chanell is too loose. I checked to make sure it was in the track and looped around correctly, but could not find any errors. Does this mean the regulater is bad?
    Also, can I take out the entire assembly with regualator?
    Thanks for the help.
  • I want to order the clips from GMpartsdirect like some of you have, but have a question. Does the clip come complete with the thing that holds the window also? I emailed them asking for a pic, but they don't email me back.

    I not only need the plastic clip itself, but the metal "clamp" that bolts onto the clip also.

    Can anyone tell me what they got when they ordered the clips from them?

    Sorry for the long post.

  • I got my from the dealer and the plastic part and the clamp(to the glass) came together. The new part is a lot heavier made than the original.

  • I ended up buying the 2 clips off Ebay for $69 bucks and all is well! I pulled out the whole regulator for more comfort and installed the babies with ease.

    A big thank you to all of you that helped me. Ain't nothing like an internet forum to help us do-it-yourselfers out.

    Now anyone know why our air cond. compressor just quit?

    On the rendezvous it is usually the condenser in front of the radiator that leaks
  • I'm sure the Freon has not leaked out. The air cond worked perfect and blew ice cold air when my wife shut it off. A little while later the compressor won't even go on...? I'm thinking if it were a slow leak, we would have noticed the air getting warmer and warmer as we drove the car.
    Who knows.

    Thanks alot for the fast reply!

  • Ok, got the clips and installed them. Running it up and down the slide looks good prior placing it back in the door. Everything seemed fine and in working order, but when I got the door panel back on and ran the window up and down to test it several times, the cable kept coming out of the nylon clip. I know for certain that I had the ferrule on the cable properly placed in the nylon slot. Why does it keep coming out?

    :mad: Is the window is binding somehow when being rolled down?

    Any answers on this?

    Thanks for your answer in advance!

    Push the little barrel in the clip HARD---you will hear it pop when it is on properly.
  • Ahhh...that must be the secret! No wonder because I just sat that mug in there. :blush: Didn't know that it had use of force was involved.

  • YUP.....but don't break that cheap cheeszy clip by pushing too hard LOL.

    jereo is correct, it will snap into place.

    Good luck.

  • I see the title was 2004 Rendezvous but all I saw mentioned in conversations was 2002 and 2003. Do the part number listed for the clips fit the 2004 also? When you go to GM direct to order, they do not come up under 04.
    Part #15286776 and 15286777.
  • Well, I have a broken clip too :sick:

    I finally figured out how to get the inside door panel off, and found the broken clip laying at the bottom of the door.

    How do I get the whole assembly out of the door to replace the clips? Does it lift straight up and come out the top?

    Thanks in advance!
  • Hey there. Pretty simple to pull out the whole regulator from the door. Once the panel is off, just remove the 4 or 5 bolts that keep it attatched to the door and pull it out through the big opening in the middle of the door. Don't try to pull it through the top, I don't think it would fit.
    Hey, I hope this helps ya! When you have more questions just ask.

    Good luck,

  • Thanks for the advice.

    I went to the dealership and they only had one clip in stock, and of course it's the wrong one. So I went ahead and bought it and ordered the other one, because I'm sure the good one will break soon.

    Also, this whole device is the weirdest contraption I've ever seen. Who on earth designed this mess of a window opener?

    I may be begging for more info once I get my hands on the parts and dig into it.

    Thanks again!
  • Yeah, I couldn't believe it when I pulled the door apart. What has GM become? My pickup is a '97 and it seems to be built alot better.

    Crappy design thats meant to fail. Oh well, thats life I guess.

    Take care.

  • My clip is suppossed to come in today.

    After the clips are installed, should I place the assembly back in the door, then drop the window into the clamps from the window slot above?

    Will I be able to get to the clamps with the unit in the door?

  • Yeah. Just take your time installing the clips and make sure the little "pellet" (we will call it that) is properly seated in the clip. This is important.
    It's pretty simple after that. Just throw it back in the door and bolt er back up. As for the glass, turn the key on and power the guides till they are half way up the door then tighten the bolts CAREFULLY. Make sure they are snug but don't overtighten and break the glass.

    I hope this all works out for ya. Good luck man!

  • You wont have any problem. The clamp is part of the clip assy. Just lower the window into the clamp and tighten it up. I'm 69 yrs old, so if I can do it, anyone can.
    Good luck, jereo96 :)
  • :)
    Mission Accomplished!

    Thanks for all the good advice and hints here! Changing the clips out was not really hard at all. I'm glad I bought both clips, because the one I could not see was also broken and hanging on by a thread of plastic. The new clips are a little beefier, so hopefully they will last the life of the car.

    I don't believe I will ever roll windows down again for no reason...

    Thanks again for the advice and piece of mind!
  • I'm glad it all worked out for ya. Just wondering, what did each clip cost you at the dealer? My dealer couldn't help me at all. I had to order mine from Ebay.
