    • You can use your existing hardware and wiring harnesses. 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 the cables and 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.
  • Nothing is more frustrating than taking your car apart and finding the part you purchased does not fit. You want the part to fit. This design is test fit on an actual door. When you install it you will have no issues.


  • 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.

Great product at a good price.
This is the second window regulator we've purchased from 1A Auto. So far they have worked fabulously. The installation videos are fantastic. Very helpful.

Motor not as powerful as OEM
The fit was exact for this regulator. Replacement was very simple. When all connected and back together, it seemed as though the motor was not even powerful enough to raise the window. I double checked the window track and all was clean, aligned and clear. Then, I started the engine, and the extra juice from the alternator must've given the motor the boost it needed to raise the window. It is functional, and not as oft used left rear window--otherwise, if it had been the driver's window, I may have exchanged for a different regulator with a more powerful motor.

Fitted Perfect
Fit just right, but is a little slower than the stock motors, as far as the speed of the window going up and down. but still a cheap fix, so i can't complain about that
