01 lesabre window regulator
This is by far the best regulator I've purchased. This is the second one I've 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 eBay's and 1A's the first time I used it after the install. The EBay one was slow and just felt like it didn't have enough power although it did do the job for a bit before giving out. The 1A Auto's regulator pushes the window up at a much faster rate which I can only attribute to a stronger motor. No lie I've even showed friends how fast the window goes up now haha. Great product that I would highly recommend! Thanks 1A Auto!

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 Auto's 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.

It's very important to really get a good look inside your door to make sure you know what you're 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 you're careful (don't lose any sockets!) and really pay attention to what you're doing (follow the video guide to a T), you can't mess this repair up, and you'll feel good about it once you're done too!

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.

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.
