Everything fit as it should.
Fit perfect no problem
It was a perfect fit, motor plugged in perfectly. I have had great service and great products from 1A Auto!!
Remember the motor is separate. You just change it over to the window unit. Take pictures of the operation especially how you removed the old unit .Also don't take out the bolts which hold the right inside rail that guides the window. I was lucky and recalled how it reinstalled. This piece has a bow in it to conform to the inside of the door . Again don't be tempted to remove the nuts that hold this piece in place. Also the window unit has three or four nuts holding the unit. 2 upper and 2 lower that grab the bottom of the window. There are some excellent videos on line. I wish there was an easier way to reinstall the door panel, but my had pieces broken and I rigged what was left. Good luck get your part from 1A auto, you can't go wrong with part or the price!
Its always easy with 1 A auto, really appreciate the way they list the parts and always there to offer suggestions. It came exactly when they said it would. Dependable and reasonable. I will always be using them for my parts !
VERY FAST & IN GOOD SHAPE THANK YOU , WILLIAM BORRELL .
I have changed those on pickups and on standard sized buick vehicles before, however looking at the extensive process to change them on a Cadillac was more than I was ready for. I purchased a replacement regulator at a very fair price. The video to install it for free was a gift to no end to me and I thank 1A Auto for providing prompt delivery and how to do it totally.
