  • 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.

Great product arrived sooner than expected and worked great when I got it in the truck. Never installed a window regulator in my F-250 before but your YouTube video helped me out a bunch. Will shop here again.

So far so good. 1A always seems to have quality parts for decent prices. Where 1A shines is their speedy service and the fact that they have really easy to follow install videos on YouTube to help you install your new part(s) correctly the first time.

Super Duty 2004 window regulator
I recommend that anyone with some mechanical skills install a window regulator after watching the how to install video from 1aauto. The regulator was easy to install and works perfectly.

Not a direct fit, had to modify
I couldn't locate my drivers door motor and regulator except through 1AAuto. There were two issues with it. First of all, it was not a direct fit, even though the description was correct, it wasn't a direct plug in, I had to cut the plug and wire it in. Second, the track that the window slides along was pinched in place, it me a few try's to figure this out, I had to remove the whole unit and pry one end loose to allow it to move freely, then all worked fine. I am so glad they had this unit or I would have been in trouble unless trying a junk yard.

Just what I needed
Somehow my regulator decided to shear off some teeth. It was hard to find a full setup for a 99 superduty front left door, but this was spot on.
Can finally roll my window all the down and up again without having to yank on it.

Instructional video got the sale
I have not installed the window regulator and motor yet, however it looks correct and like quality product. The reason I purchased from one a auto is because they offer instructional video, and the price was excellent. The shipping was quick and so far I am satisfied. If the product works as advertised, I will continue to purchase from one a auto
