• LH (Driver Side) FRONT
  • Does NOT include power window motor
  • 100% mechanically tested prior to leaving the factory

Please Note:  This window regulator is designed to work with factory style motors only.  Due to variations in aftermarket designs, replacement motors may not have the correct gear style.

Please Note: This window regulator is a high quality aftermarket part that meets or exceeds the performance of the original.  It has been subjected to extensive testing and quality control standards.  That is why we offer this regulator with our superior warranty!


  • 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.

Right Part at the Right Price
I have now replaced all 4 window regulators in my wife's Cadillac, and one in her mom's car. This has been over a period of 9 years. The 1A Auto regulators installed easily, no modifications or adjustments needed. The instructional videos are a huge help, since removing door panels can be problematic. The original regulators started failing at 4 years of age, so you can see the 1A regulators are lasting longer than the factory units. The cars are 2005 models.

Thanks 1A!

P.S.: Their Trailblazer regulators are great too!

Solved my broken window operation!
When my power window quit working I was really stressed out over trying to fix it myself. I had paid over 200 on several other cars and said I'm going to try this myself. Fast shipping and great price and warranty and it fit perfectly, which made installation go really smoothly. I love 1AAuto.

Overall quality of the window regulator
The part was well worth the 35.95 and it did fit without any modifications, however the overall quality was not equal to the original GM part I replaced. Fortunately the car is 16 years old and I won't have to replace this part again.
