Ok so this has happened about 8 times now in the last 5 years as the window regulator is made of junk.. This is a project that is best done by yourself as you will be out tail loads of money if you take it to the dealership. I have had the drivers side go out 3 times, rear passenger x 2, rear driver x 2 and now front passenger today. Go to one of these 3 auto parts stores (advance, autozone, or o'reilly) and purchase the new window regulator (this one is the window motor too). This part has a limited lifetime warranty. Now unless you get in a wreck and break it.. It wears out from normal wear and tear which is included in the warranty... SO SAVE YOUR RECEIPT! (I copied mine into MS word on my computer, then saved it on an external hard drive (ask your teenagers how to do this if you don't know how). Anyway, when this breaks on you after a year or so. you can go get a new one replace it and take the one under warranty back. I am a 47 year old Army wife who has learned to fix things on my own...not a mechanic... but I can turn a screw driver and a ratchet. It is not that hard in fact there are you tube videos that show you how. I used this one for the front passenger door and stuzman52 made it easy. there is a part 1 and 2. https://www.youtube.com/watch?v=UZQd-9oRLok

Have fun and save lots of money...

We repaired the passenger side window motor first and then the back window fell down and we needed to get that one and another. I know for a fact my daddy's 1955 Cadillac didn't have problems with the window motors so why do almost all of the cars we buy have this problem ? We don't stick gooey candy on our windows or sit snuff out the car windows. My father in law buys us Buicks because it is a part of his religion . Even as a gift , we have had to pay for some repairs that were annoying . Thank you very very much.

First, my passenger side rear window fell down and it wouldn't go back up. I ended up taping it up for a few months with Gorilla tape just because I never had time to get it into a shop. Then the driver's side rear window did the same thing. I taped that up for a bit but I was getting sick of re-taping it all the time so I ended up taking it into an auto glass shop. They offered to replace the regulator because it had snapped in half or just make them stay up by using other means. I had them just make them stay up since I still had working air conditioning. All they charged me for was labor since I think they just used a few screws to hold it up.

I purchased this LeSabre brand new and at 20,000 miles the rear passenger window fell down. The dealer didn't cover it, had to pay $420.00. Since then I have had it happen to every window and I have 57,000 miles on it.

I complained to the General Motors consumer complaint department every time but with no satisfaction as far as any recall's on the problem. I was told they have not any one complaint about that problem, like I am the only one. They said I should take it to the dealer every time it happens so they can document it and can look into the problem, told them I can't afford to pay the outrages prices at the dealer for a fix that is never going to end due to the poor design and cheap plastic part that keeps cracking in the hot and cold causing the windows to fail.

They want you to purchase their vehicles but won't listen to you when there is a problem, and I love how you are supposed to be covered bumper to bumper under the warranty except for almost everything that goes wrong. The real pay off is that my husband retired from GM after 34 years of service and that doesn't even make them do something about looking into

a recall. I will not purchase another GM Vehicle.
