Please Note: We are committed to offering the absolute best value for our customers. If you want a highest quality window regulator at a great price, please see our other "High Quality" window regulator listings. If price is your main concern, we are offering this economy style window regulator as well. It is the same one that most internet sellers are offering. While this window regulator is a good replacement, it is not backed by the same warranty as our high quality regulator.

Installation

  • 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.

Quality

  • 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.

Value

  • 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.

Lifetime Warranty

This item is backed by a Limited Lifetime Warranty. In the event this item should fail due to manufacturing defects during intended use, we will exchange the part free of charge (excludes shipping charges) for the original purchaser. Please keep your invoice for proof of this warranty.

Easy install
This product was an easy replacement for my k5. It fit right into the existing factory holes and functions flawlessly. I went from power to manual. The price was better than those of the bug chains. The only thing I would recommend would be if they sold the install hardware or it came with it.
