My 2005 Cadillac cts has had all the window regulators fail at one time or another. This was the fourth one, and instead of shelling out about $500 dollars at a dealer/auto repair shop, I decided to try myself. The 1A auto youtube video of how to repair the window regulator was spot on. I followed the directions to the T and it works like a champ. I will always check with 1A auto first for all my repair and parts needs. Thanks again. Bob in California
