    •  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 unit
It went in good. The vids are definitely helpful. Works well. There is a slight rattle in the door now, but not sure what could be. The price was great. Would definitely recommend the product and the website.

Great experience!
Had to replace the driver-side door window regulator on my 2003 Ford Explorer. Great video instructions - couldn't have done it otherwise! (Only minor issue was the rivets you have to drill out on the 2003 Explorer were a smaller size than mentioned in the video. Careful!!)

The part fit well and shipping was fast! Thanks! A+

Extremely pleased
I recently purchased this window regulator with motor for my 2004 Ford explorer. I was very pleased with how precisely the product fit,all the holes and electrical connections, everything fit perfectly. I actually found 1aauto.com through the YouTube video I watched on how to replace this assembly. Between that video with step-by-step instructions and the quality of the product the repair was simple .
