  • 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.

Installed Fairly Easily
With video, removal was a breeze and installation was pretty easy. The final step of attaching window to the regulator was challenging mainly because the channels needed lubing!! Did not want to move up and down very well at first. Actually thought it was installed wrong. Finally gave up and visited our friendly body shop. They said all was fine but just lube the window channels. Once done works great no noise!! Would recommend the product. Just make sure and lube the channels!!

Perfect Replacement
I have replaced two Window Regulators on my 1999 Buick Century, both replacement parts were from IA Auto. The driver side and the left rear passenger window units had broken with age. Just used the same screws I took off the broken unit to install the replacement. Very easy, just watch the video!!

I need to make sure that this product comes with the 3 screw door mount of the right size? Upon dealing with other makers of the product, the mount doesn't come included, but it's necessary.
