Sway Bar Problems of GMC Envoy

I have a 2004 SUV XLT. I bought my car with 400 miles on it. I had the gas tank replaced early on. Went back to GMC b/c they had not installed it properly. I've had both front and rear sway bars replaced and both knock sensors replaced. My middle window decided to quit working and I haven't gotten it fixed because the guys at the GMC service center said they couldn't imagine what it could be and they would have to charge me $100 for a diagnosis!! my radio/cd player is only half lit up and stops working when it gets too hot from playing a cd. . . I am currently having issues with the fan clutch, thermostat and a leak in my front differential. Meanwhile the guys at the dealership wanted to charge me $1,500 to replace my knock sensors again and didn't even find the leak when they were "diagnosing" my issue. I truly do love my car, but I am super mad about the middle window and super mad about all of these issues. I take care of my car and do all of the routine maintenances. I think I know why it was only on the market for two years. Please help us get our middle windows fixed. I didn't do anything to cause it to stop working.
