I have just purchased the second regulator motor assembly in my 2000 Buick Le Saber. Total cost for the part only $280.00 (sarcastic). There is no redesign of the new part. It is a plastic guide which slides up and down on a track pulled by 2 cables. Gm could have made good by selling a replacement plastic part for a few dollars, but they continue to alienate their customers by forcing them to pay for the entire assembly. I would not buy another GM car if my life depended on it.

I own a 2000 Buick Regal GS and love it, but it has certain "quirks". I have fixed 3 power window regulators and I'm considering fixing the 4th before it breaks. The first one took me 4 hours, but I did the the last one in just 1 hour including finding my tools. (You will need a T-30 torx bit for one of the screws.)

I repaired the mechanism each time, instead of buying a new expensive one. The problem is a cheap plastic part that holds the 2 ends of the cable that moves the window. Stress, heat and age cause the plastic to become brittle and crack.

To fix it, pull out the whole mechanism, take it apart, put both cable ends back in the plastic holder, and put a sheet metal screw into the metal to hold the cable on the broken side. Then make sure the cable is winding properly on the spool and reassemble the unit.

The other problem I have had is the Air Bag Light comes on for a few days at a time. I've had it to the dealer, but they have never found anything. It's just a pain and I don't know if it's reliable.

It's too bad they are discontinuing the Buick Regal line instead of fixing the issues. The supercharged V6 engine is my favorite and I'll probably have to buy a Pontiac Gran Prix instead.

I have owned and been quite satisfied with 9 new GM vehicles during the course of my lifetime. One of those purchases that I had great luck with was a 1989 Buick LeSabre, and in time I decided to purchase a newer 2000 model when they first became available at the end of 1999. I bought the LeSabre Limited with all the bells and whistles. I owned the car for 5 years (75,000 miles.) and couldn't wait to trade it in on something different. I have literally spent a small fortune keeping this car on the road. I have replaced 5 power windows at about $400 a pop. I have replaced a number of sensors that have run up into the $1000s. I have also replaced one power seat, two power mirrors, and numerous other parts. Definitely not one of Buick's best efforts. It's sad, because at one point in time I was considered a very loyal Buick die-hard, but I can now state for the record that my 2nd LeSabre was not only my last Buick, but my last GM product as well.

Add me to the list of Buick owners with rear window regulator failures. This is a window that almost never is used. The window obviously didn't wear out. The little plastic slide in the regulator broke. I am a do it your-selfer so will attempt to fix it on my own, wish me luck. I've enjoyed my Buick, but now I am finding out that I only need to look forward to more windows failing..I've seen so many posts. I'm ready to trade the car in, and it won't be for another Buick!

I bought a 2000 buick lesaber in 2001 and now all four windows are working. I can hear the motor, but they do not go up or down.

My wife's 2000 Le Sabre also has gone through 3 window regulators. I found a place in Mass that has them for $100 which is about one third of the GM price. We will have to see if they are any good. I guess they have to be better than the GM versions. The GM regulators are mechanically well made, but the quality of the plastic molded parts is the worst I have ever seen and I was once in an industry that used a lot of molded plastic. All my three failures were due to the plastic parts breaking.

I have a 2001 Buick LaSabre Custom and I have had both rear regulators fail. I have also had to replace the front left wheel bearing. My car has slightly less than 90K miles. The window regulators failed within two weeks of on another.

You can have the window requlators rebuilt for under $100. I have tried to figure out why GM/Buick would put such a bad part in one of their cars. The only thing I can come up with is to protect the window which at the dealer is over $1400. By the way, I have replaced lot of regulators over the years and I thought that the way that all the other parts in the door area, (door film, panel, armrest support and ect.) were a vast improvement over others that I have seen.

I had a 95 Riviera which I had the transmission fixed or relpaced 5 times. The cost to repair was over $1500 each time. Before 100k miles I had replaced under warranty the transmission, supercharger, the master cylinder, a/c compressor and cruise control. In the end I had replaced the driver's window motor twice, alternator, a front wheel bearing and the harmonic balancer twice and motor motors. The oxygen sensor was replace three times.

I have had Cadillacs and have felt that they were better built, but even its parts were out of site at the dealer.

My Hondas and Acura have been far better cars. GM needs to wake up and see what the are doing to themselves. My wife and kids tell me that I better off with Honda

Wow this is surreal. I had the same problem with my 2001 LeSabre and my neighbor did too with her 2002! Same thing, the passenger window. Now I am having problems with the electrical system. I go to start the car and it just dies.

Have had it to the dealer and they said it was the battery.

Anyone out there with the same problem. The dealer insists it is not the alternator or starter. Please help out there!
