1A Auto saved me $465... Thank you!!!!!
Cant thank 1A Auto enough. You guys saved me $465. My local GMC dealership wanted to charge me $550 to replace the broken window regulator. Not sure how then can charge that price when it takes around 30 minutes to replace. Your video and instructions on how to replace this part was dead on!! I just brought out the iPad, started up the video and replaced the part with NO PROBLEMS at all. It took me 30 minutes. Im sold on A1 Auto. Thank you once again!!

A perfect fit & works great
The part fit an d works perfectly. Same brand/part was almost twice the cost locally. Didnt need it the same day so waiting for it to be shipped was not a problem. It arrived in a few days which was sooner then expected. I will use 1A AUTO in the future.

Easy to fit but took a little more time due to way it broke.
Mine broke in full up position so I was unable to lower the window etc as per instructions. I had to loosen the glass bolts and lower the whole unit away from the glass then twist it out of the door. New one went in fine and works well.

Totally Satisfied

The right part
I had the right part at the right time. When you need something like this you dont want a hassle. You just want to find the right part, get it ordered and have it arrive so you can get on with life. I used 1As video to help remove the old one and replace the new one. Window works fine and can move on.

As good as OEM
I purchased a window regulator with motor and I am completely satisfied with the part it works better than the original and even though I am mechanically capable of doing it myself its always great to have a frame of reference for any repairs and replacements. Thanks to 1A Auto for the parts and customer oriented services.

Customer Q&A
Ask a question to 1A Auto customers who purchased the product
This wouldnt fit on my 2002 envoy xl?
Darien W May 18, 2017
No, the rear doors on XL models (7 passenger) are longer and require a different regulator.
Tim K May 18, 2017
I did not know that the longer version of the trailblazer would have a different regulator for the passenger door than the shorter version.
Clarence M May 19, 2017
I believe the Xl uses a different part #
