Great part for even better price!
Thank you, the part works great! It was a great price, easy to install, and continuing to work well! I dont know if most 2010 Impalas have this problem but I need to replace the driver aside passenger window regulator, as well. I will be taking care of it in the near future.

Power window regulator & install
Bought from this company because of the great videos & the price was within a buck or two, either way, of other companies. I must say the removal & installation was far easier than the video, with the removal of the door panel being the hardest part. It works fine. I dont relish the idea of having the other one break in bad weather, so Im thinking I should replace the other side as a precautionary measure after all these years. It was that easy.

Most satisfied
I was impressed by the savings, quick order delivery, customer service, how to videos, and the window regular price at $44.95. I priced this item at Auto Zone and Merles Auto only to be told it would be $240.00 and more. Window regulator fits and works great in my Impala. My sincere thanks and new loyal customer...Alex

Window Regulator
The part was easy to install. The instructional video shows you exactly what you need to know. The total time it took me to complete the task was about 30 minutes.

Great product easy install
I had my factory window regulator fail and was in need of a replacement part. Searched at my local auto parts store and was in shock of the extreme price of the simple part. Stumbled upon the 1 A auto website and just for a giggle searched their site for the part. I ordered it immediately. The price was a fraction of the auto part store and the how to video made the installation a breeze. Will definitely be a repeat visitor in the future.

Thought they sent me the wrong part at 1st.
When I 1st unpacked it I thought they had sent me a drivers side unit instead of the passenger side I needed because the motor appeared to be oriented 180 degrees out from the original I had just removed from my car. I later figured out that they had changed the design slightly from the original and that it was indeed the correct part. Works like a champ! Will buy from them again!

Great product, the video really made the install simple and easy to do myself.

Impala RR window regulator
Part fit like a glove. follow youtube instructions and it will take a 1/2 hr or less of your time. Zero problems. Id bet the dealership would have charged me over $75 in labor for a job that took 20minutes. Im the least mechanically inclined in my family and I didnt have to call the mechanic family experts for help!! The door latch cable is tricky to get in/out of clip. Push ears in and pull through, then just push back through once you re assemble. I kept trying to pull up at first to get it out of tab.
