Straight-forward install video, OE-style part
I've ordered from 1A Auto a handful of times and have been happy with the fast and free shipping, and also the fit and finish of the products. This product is no different. The regulator came in a sealed bag inside of a box, and the area where the slide operates was already lubed and ready to install, which is nice so the installer doesn't over-lubricate or use the wrong type and gum up the mechanism. It looked and fit just as the one that was removed and functions well. The install video was easy to follow and should help even a novice complete the install quickly and easily. I recommend it for anyone needing a new regulator.

Auto Part
i live in a rural area, so having auto pars delivered to my place saves me time and money. Also, the part that I ordered was less expensive than if I would have purchased it through an auto parts store, and i could tell it was well made.

Perfect Replacement
I have replaced two Window Regulators on my 1999 Buick Century, both replacement parts were from IA Auto. The driver side and the left rear passenger window units had broken with age. Just used the same screws I took off the broken unit to install the replacement. Very easy, just watch the video!!

Buick Century window regulator
Installation went pretty good. My only concern is that the window doesn’t operate as smoothly as the old. It seems to slow down when it gets to the top. Hope it lasts as long as the OEM.

pleased as usual
I ordered a window regulator for a lady at church and installed it for her. As usual the parts fit and function perfectly.

The how to videos are sometimes very valuable ; although this task I've done a few times before.

Easy to order and forwarding follow up is great.

I need to make sure that this product comes with the 3 screw door mount of the right size? Upon dealing with other makers of the product, the mount doesn't come included, but it's necessary.
Julian G on May 13, 2017
BEST ANSWER: Our parts are designed to be exact replacements for what came with the vehicle, so as long as your year, make, and model match up with our listing, these will definitely fit and function just like the original, and the bracket will be the correct size. Please let us know if you have any other questions.
Does the window track and cables come as one assembly all together with the motor?
Jeff K on Jul 2, 2018
BEST ANSWER: Yes, it is a complete assembly just like OEM. There are bolt for the track assembly and for the motor. Also on the window its self. As you remove the old regulator pay close attention to where and how it is mounted and put the new one back in the same way. you will need to tape the window up with duct tape while your removing the old regulator and installing the new regulator, then lower the window down to attach it to the new regulator. Relatively easy. Carefully remove the plastic moisture liner to get into the inside of the door, and be careful to not rip it and the glue they use can get messy, as reinstall it make sure to get is sealed down well, that is what keeps the water and wind that can come down the window from coming inside the cabin. Enjoy, should take you about an hour or so, and save you a boat load of money from hiring it done,
