  • Windows that don't work can be frustrating. They can also hurt your vehicles value. An inoperable window could mean $200-$500 discounted off a dealer trade value or asking price.
  • Some shops and dealers charge more for parts and repairs when they think you don't know what is involved. Now you can get the value you deserve. Knowing what this repair entails can be the difference between the value of doing it yourself, or the pain of a costly repair bill.

Rear window track replacement.
I would highly recommend A-1 Auto. I watched the video your company provided on line before I ordered and while I was waiting for the delivery. Never removed any door panels etc, however it went really smooth thanks to the on line video. Only one issue I ran into. The track was in the up position and I could not line up the studs with the holes. Fortunately my wife had me run the track to the lowest position and it fit right in. (she used to work on our chevelles with me and is mechanically savvy) I would have given 5 stars if not for this little glitch. If it was in the video to have the window track in the lower position and I just missed it then please add the 5th star. Thanks again for your on line video and free shipping.
