This window regulator and motor makes a great replacement and has good cost savings over a dealer unit.

  • 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.

Window Regulator Read Driver Side replacement
This regulator was just the thing I needed to get my Buick window to roll up! After checking the 10:13 minute video that 1A provided, I had no problem fixing it myself! I am a 64-year-old farm wife who got tired of waiting for someone else to fix my window, so I did it myself! I am very happy with 1A Auto Parts and for their instructional video! - Virginia

Easy and smooth
After watching YouTube video showing removal of failing regulator I had confidence to make the swap myself. Maybe 15 minutes start to finish. No issues.
