  • This repair is easier than you may think. You'll find our installation videos helpful. In our experience removing and replacing the door panel is the most involved step in the repair. On most vehicles this only requires removing a few screws and push-in clips.
  • You'll get a great feeling of accomplishment after you complete this repair knowing you saved money, and you didn't have to give up your car for a day at the repair shop. Your passengers and other drivers will be amazed.

Fit guaranteed

  • 1A Auto will refund you with no hassle, if this window regulator does not fit the application stated.
    •  This regulator will install just as your original does. Save time and money.


  • Be confident this part will work right. Every regulator is tested after assembly to make sure all mechanisms are working correctly.
  • It is important that your new regulator works for a long period of time. The design of this regulator is tested to withstand 10,000 cycles. That is enough to raise and lower your window 3 times per day for 9 years.


  • 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.

Impala window regulator
My wife has never lowered the rear windows on her 07 impala. Naturally the first time I lowered one it would not go back up. It only took me 20 minutes to install and that was with a beer break. Local auto parts wanted $239 for an aftermarket. The plastic guide that slips on the rail is much better than OE.

Before: Window fell into the door. After: Works like new
Ordered the Window repair assembly. Arrived quickly. Installation was very easy and the online video helped in the decision not to take it to a dealer for an expensive repair.
The part seems to be of OEM quality and it works just like new.
Overall experience was great. I would highly recommend 1 AAuto.

The right part
This was an exact replacement for the failed regulator motor in my daughter's '07 Impala. The only differences were a long pigtail on the wiring for the motor which plugged right in to the factory connector and it mounted into the door with a couple of studs with nuts rather than the factory bolts. No problem with either one. I secured the pigtail with a wire tie to prevent it from interfering with the operation of the window. Hope it lasts another 10 years.
