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
The process I used to order the part was easy as was the check-out procedure. The video I used to install the part was very good and it would have been a real problem without it. I actually ordered the wrong part and wanted to return the wrong one. The person who helped me was great. I did not return it due to freight costs but, in the end, my overall cost was much cheaper than going to a mechanic and I still have a regulator for the other side of the vehicle if I choose to use it. I will use A1 for my future parts needs.

Window Regulator
I ordered a rear window regulator for my 02 Explorer from A1 auto. It arrived fast and the price was good. Unfortunately it had problems out of the box. I took it out and boxed it up for return then called customer support for a RMA or credit.
I spoke with a young man who apologized for the problem then told me he was sending out another one to replace it.
He told me to dispose of the one I just received as they didn't need it returned (how easy was that).
When the new replacement part arrives I will install it and hopefully everything will be fine.
Customer service got five stars and the part got 4 since it was defective so ended up with 5 stars as I didn't have to ship it back!

Thank You for the Part AND The Video Instructions for Installing It!
We are thrilled with our regulator! Thanks to your video instructions and quick shipping of the part, the window works like new! We saved a ton on labor and did the job ourselves for the $50 cost of the part. We will be visiting you again the next time something breaks on one of our vehicles. You are great!!
