Works great
Works great and the video was spot on. Free shipping was a little too long. Nothing should take that long to ship anymore. Also to have it shipped sooner was a ridiculous price. Was not going to include this information but you required at least 50 characters on the review. So while looking for something to say I was reminded about the shipping. That's also what made me take it for my five star you to a four. No one wants to be told the length of review they have to write.

Exactly what I was looking for at a good price. I had a different regulator when processing my order when deliver. I call back gave them my Vin# they send me the correct one. I didn't have to wait long.

Best Price, Quick, & Excellent Video Instructions
This is a great way for anyone with even basic mechanical ability to save lots of money. Excelkent quality, and unlike the dealer, it includes the motor at nearly $100 less total cost. Free shipping that had it herd in about 5 days including the weekend. The video was excellent for how to gain access and to replace the window regulator. Because of that, I tried buying the part from 1AAUTO, and I was pleasantly surprised to find the price the lowest, the shipping free and prpt, and the quality obviously as high as possible. I will look to 1AAUTO for my next need as well. Absolutly impressive!

After replacing rear window regulator the window gets stuck in the up positioning why does the window get stuck with rolled all the way up?
Judy V on Jul 27, 2017
BEST ANSWER: When installing the regulator make sure the support bracket on the window is snug not tight. Let the glass rest on the bracket. Control the window switch to adjust the correct fit. Once you had done this keep the window up or down at your convenience then tight up the brackets. Good Luck have a great day
