Regulator fits
This was the third time that I have used 1A, and the results were the same. The part that I received fit just like the OEM part.

Good Product!
Installation was a snap, excellent video showed all the steps. The price was cheaper than I would have thought, but the new regulator from 1AAuto works perfectly. I will buy again from them.

Support the Help Videos
The product works fine and solved the problem. I use the help videos all the time and I wanted to return the favor. Price was competitive and shipping was fast.

worked as promised
This part fit fine , I have a 2000 Lesabre the first year of the new body style , the how to video helped a lot but this first year has a different bolt on , body panel removal then the video , just want to let people know that a clip holds the door panel on that can break if forced. Over all it is working and took less than 45 min to install.

I couldnt get the video to play for instruction but the step by step instructions got me through the install just great! I recommend this to anyone trying to save 80$ from the local auto store prices. (Oreally had it for 139$ and I got it for 50$).

Junk, do not buy!
I bought this 2 months ago and it failed already. I called and was sent a replacement which only works sporadically. The problem is the curve of the regulator does not match the curve of the window or the track. This causes it to slide hard in the track. Window slides up and down fine without the regulator attached. Im going to buy a different brand at the local parts store and throw away these two. 1AAuto is usually pretty good but I wouldnt buy another lesabre regulator from them. I had one for a different lesabre from them that didnt go all the way up.

Great service
The part that I ordered was correct and works great. It arrived earlier than I anticipated and was packaged securely. The price was great also.

It works
It works, but we all know none of these are built to last. Lots of plastic parts.

Quality parts for a decent price.
My car failed inspection due to the motor crapping out on the regulator, and the shop I normally frequent wanted just short of $400 for a regulator replacement ($150 for labor, and the rest for parts.) While I understand they need to make money too, I need to get my car back up and inspected, so I did some research, and as a long-time viewer of 1A Autos video guides, I ordered the parts myself, and had the regulator installed within about an hour and a half (and am now missing a 10mm socket, which is now stuck in my door), while working in near-pitch-black darkness. Its very important to really get a good look inside your door to make sure you know what youre looking at, as well as watching the video guide a time or two. I saved myself a little under $350, and now know more about my car door and how windows regulators operate than ever before. As a separate note, the parts were well-made, and I certainly felt comfortable installing them in my car, and the guide that was linked on the part page was indispensable. They shipped out quickly, and arrived within 4 days. Of course, there are parts on eBay and other websites, but the clarity of their video guides and detailed information on troubleshooting the issue really gave me the confidence to choose to buy from this company. So, in essence, this was a worthy investment, and as long as youre careful (dont lose any sockets!) and really pay attention to what youre doing (follow the video guide to a T), you cant mess this repair up, and youll feel good about it once youre done too!

Replacing regulator
Works great=I watched your video last year to replace passenger side regulator, which made replacing driver side easier. I made one mistake and forgot to plug in door locks and had to remove door panel and plug it in. Learn by your mistakes, right? I know it is a 2000 Buick just hope back window regulators hold out. If not I know where to order from Thanks Tim

01 lesabre window regulator
This is by far the best regulator Ive purchased. This is the second one Ive replaced on my Buick. Of course the first time I decided to go cheap and use EBay. Within a year it went out. I could tell the difference between eBays and 1As the first time I used it after the install. The EBay one was slow and just felt like it didnt have enough power although it did do the job for a bit before giving out. The 1A Autos regulator pushes the window up at a much faster rate which I can only attribute to a stronger motor. No lie Ive even showed friends how fast the window goes up now haha. Great product that I would highly recommend! Thanks 1A Auto!

Awesome and thanks
When your window is stuck halfway down in zero degree weather, you need to get it fixed. I watched the repair video and got on the phone to order the part at a great price. Thanks to your fantastic shipping, it was repaired two days later. Thanks again.

Replaced window regulator.
I purchased a replacement window regulator from you guys after doing some research on how to do it myself and foundd your video series. Watched the video and ordered right from your site. Not being a "car guy" but a handy guy, your video showed me how simple it is to change it out. This is key because I received a quote of $350 + to have it repaired from my local repair shop. The part I ordered was $50 and some change and it took me all of a half hour to fix it myself. Thank you 1A, for showing us beginners how to and to save some $$$$. Will definitely buying more parts from you in the future.

Fast delivery and easy install of Buick LeSabre Window Regulator
1AAuto is the best for instructional videos for DIY hacks like me. I rely on them frequently to provide the right parts for my vehicles and walk me through the repair steps. On-time delivery and quality part for my LeSabre driver window regulator. Easy to install.

First Class Service and Information - saved me a lot of $
I was faced with a costly problem with my wifes 2004 LaSabre! The drivers side window stoped functioning. She was told at the Dealer that it would take $700.00 to fix it. I went on line and found your video on how to fix it myself. Even thought I am 87 years old I knew I could fix is myself after watching your video twice. I ordered the part from you and had it in 3 days. The next morning I had the door window fixed and running smoothly in lexx than 30 minutes. Great solution and service. D. E. Mann

1aauto has been a pleasure to deal with
I have ordered several parts from 1A Auto over the years. All of the parts seem to have held up and work as they should. Only one instance that I have had to contact customer service and it was a real pleasure and everything was taken care of to my satisfaction with absolutely no problems.

October 17, 2018
I went down to a place to get my windows fixed because both windows went out at the same time so I went down to try to get the driver side door fixed and they are going to charge me $238 for one door. I thought that was ridiculous so I got online order the parts from 1A Auto watch the video on how to install replaced both window motors and regulators took me 15 minutes a piece and I saved a lot of money thanks 1A Auto you guys rock. I will definitely use you guys again thanks for the fast shipping and a great product my windows work great
October 25, 2018
Window regulator worked great, video instructions were very helpful. I also purchased front struts and again the video and the struts worked great. The cost was half of what the auto parts stores were wanting to charge. For a person on a fixed income I highly recommend 1AAuto.

2002 Buick LeSabre driver window regulator
This is my second regulator for this car. Both from and the parts along with videos, the entire ordeal was totally simple. Id like to thank Mike Greer for providing such a detailed video which provided everything that a person would need in replacing their own regulator. Great prices too. So, do you think Id recommend a person to take advantage of 1aautos quality parts and excellent help? Well YEAH...... Its a no brainer. Paul Burkett

Window regulator replacement
Car was bought for niece in college 300 mi away. Rear window regulator failed before we could get it to her and ordered new one from 1A. Part arrived as advertised, watched video of replacement, mainly to see where the fasteners were that held on the inside door panel. Replaced with no problems, very good fit and everything worked. Got car to niece and right away driver window failed. First regulator fail was due to nylon parts breaking and some study of the situation revealed that the car probably spent considerable time in AZ and heat had weakened the plastic so decided that replacing all the rest of them would be in order. Ordered the other three regulators with motor but only two were available so ordered that one without motor and used original motor. The changeover went as advertised with no problems at all. Got niece home for weekend and we replaced them all in an afternoon. After she seen what we had to do, she ended up helping and as I was finishing up one and on to another, she did one of them by herself. Dealer price$185 1A price $53. 5stars for that. Free shipping if you can wait about a week, faster methods available. Used 2day shipping ($40) to get parts in time for weekend the second time and they got there accordingly, 5stars for that. Customer service friendly, knowledgeable and helpful and reachable by phone, 10stars for that. Highly recommend.
