2002 Volkswagen Jetta wipers, windshield & visibility problems

Seat heater malfunctioned, burned through the leather seat and burned me while I was driving. I safely pulled the car to the side of the road. The replacement components also malfunctioned, burning the leather seat and once again, burned me. Also, the sunroof has plastic guides that keep breaking, I have had these plastic components replaced three times since I purchased my car in 2002, and I don't use my sunroof that often, probably less than 30 times/year.

My driver's side window suddenly stopped working. I took it to a repair shop and the mechanic said that piece that holds the window in place was stretched and about to break. When I spoke with a friend who used to own a jetta of the same year, make, and model as mine, he said that the same thing had happened to his vehicle. He said that there had been a recall on this part. When I checked the nhtsa's web site, however, I could not find this recall.
