A used car dealer K And W Motors in New Hampton Iowa sold me this car like this. The rear passenger window on the driver's side never has worked. The car has had a lot of issues for 4,400 dollars that I bought it for, even the gas guage doesn't work. I used to like these cars but won't buy another one.

2002 buick lasabre passenger and rear windows all quit working at same time.

have serched internet and found it may be regulators, just seems hard to believe

that all three would go out at same time. also door locks quit at same time

Started as an intermittent problem. Dealer couldn't find the problem because it wouldn't occur when the car was in for repairs. Now the warranty ran out and it's a permanent problem. Dealer won't fix it under warranty now. How does the door panel come off so I can troubleshoot it?
