Working great
Ordered the pair to replace the broken one on drivers rear. Read that if one goes the other will follow. Watched to how to video from A-1. Very good tutorial. Took me about thirty-five minutes to replace each one. So far all is good.

One Happy Customer !
The Cadillac Dealership wanted close to $800 to replace the window regulator in my wifes Cadillac. I ordered the part from 1A Auto and watched the installation video. The part came quickly and after a 45 minute installation, the window was fixed at a cost of less than 1/10th of the dealership estimate. Im one VERY happy customer will return to 1A Auto for any future parts needs. The window works perfectly and the installation was snap (even for a 65-year-old, who stopped "twisting wrenches" years ago) Thanks 1A Auto !!
