2003 GMC Envoy XL wipers, windshield & visibility problems

The 2003 envoy we purchased gave us numerous problems, including a number of the ones other owners mentioned here, like the glass liftgate that does not operate properly, various electrical problems, but especially the outside rear view mirrors that move on their own no matter how many times they were supposedly fixed by service technicians. They do not stay in the position we set them in, and the fuel tank leaking is very dangerous as well as inhaling freon because of malfunctioning A/C system.

The rear driver door popped open and won't close. The fan clutch failed 2 weeks after I purchased the vehicle. I thought the transmission went out because it was winding really high and not driving normally. Also the rear passenger doors on both sides have malfunctioned. The window on the passenger rear went out. I have not corrected the failures as of now.
