Three of the four window regulators failed. Metal wire broke on all three. 50-70 dollar part. Paid dealer $500 to replace the first one. Did the second one myself and it took 1 hour 30 minutes, only 15 minutes to replace the third one. Found a great instructional video on youtube.
The three passenger windows quit working. They wouldn't stay up either. Evidently there is some kind of cable something or other in it, and that came apart and got all knurled up in there. I don't know cuz its my x's car and I never took the panel off to look at it. But anyway, the driver window is fine, the other 3 are not working and one has a wedge holding it up.
Both driver's side windows failed in the "down" position. The motor would run, but would not engage to raise the window. Raised rear window to full "up" position, held it there, and disconnected power to switch. Replaced regulator (I think that's what it's called) in front window. Original-type mechanism no longer available, so had to purchase extra parts that had not failed in order to make window operational because the part has been redesigned by manufacturer. Window works now, three years later, but is noisy and very finicky--I use window as little as possible.
Power windows went out on 3 windows. Today, Driver window went out. Trying to get Driver window raised for security and weather purposes. Can hear the window motors activate, when pushing the button levers, but no avail.
Have gone through this with all for windows now. Costly repair at the dealer!! Don't get parts at a salvage yard. Find a local mechanic who will not upcharge on the parts. Windows are definitely needed before your ac goes out too!
Buy a new one .. I suggest getting window regulator with motor... But if you can hear a noise when hitting the button then your motor is fine.
Rockauto.com is the cheapest I've been able to find. All there parts (from what I seen can be cheap/ OEM.
Get some spark plugs, wires ect for the money your saving. Bessy Da Buick loves me for it.
On my 2000 Lesabre previous owner had 3 power windows brake. The 4th broke for me. On my 2003 LeSabre 1 window broke. Motor or regulator each time! Buick should have recalled the power window parts!!!!!!!!!!!!!!!!!
