Windshield Wiper/washer Switch problems of the 2000 GMC Yukon

First passenger window stopped working, found out it was the window regulator. Have been waiting for the part for months. I have been told by both gm and my auto part store there is a shortage and the auto part store says alot of gm owners have been requesting that part. Still waiting and driver window is starting to go. There must be a problem. Please check into.

Within a 4 month time I have lost my driver-side window, front-passenger, and rear driver-side window all to failed window regulator or motors. Moreover, more recently I have had the random window blow-out in my cargo area. Not to mention the throttle sticking. This is unreal, what a nightmare, cute to drive horrible to own!.
