2001 Buick, purchased new. Both rear window regulators were faulty. One cost me $600 to have a GM dealer repair it, and the other cost me $200, only because a friend fixed it for me for at his cost.
The first window, passenger side rear was when the car had about 32,000 miles on it, and the other back window failed at 35,000 miles. I rarely even used those back windows, and I almost never have a back seat passenger, so it was not due to use or abuse. The window made a gritty sound when I tried to close it, and then just failed after a few feeble attempts to rise.
This is maddening and expensive. Buick/GM ought to stand behind a car that cost me over $28,000. Since LeSabres are no longer made, I suppose they will blow us off since we are not future buyers of LeSabres.
Well, guess what... I won't be a future buyer of ANY Buick after this fiasco. It makes me cringe to even use the front windows now since they may follow suit at any given moment.
I am generally pleased with the car other than the faulty window regulators.
Ask me again once I hit 38,000 miles. I may have another opinion then.
You're not the only one to have problems with the windows. I had to replace all 4 before it was all over with. GM knew the windows were junk from 99 models up, and would do nothing to correct the problem.
Those rear window regulators seem to be a chronic problem on most GM cars in the 2001 model year. I have a 2001 Olds Aurora, and I found out about them very fast. That's why I never open the rear windows.
Does anybody know for a fact that GM changed the window regulators used in later models of the LeSabre? You don't hardly see any complaints of newer LeSabres ('03-'05) with this problem. My aunt has an '03 with about 50,000 and the last time I asked them, they had not had any problems with the windows. I am considering trading my Park Avenue for a late model LeSabre but I don't want to deal with the hassle of defective windows.
