To me it sounds like you have a few minor problems; nothing too serious.

Anyway, first with your A/C the problem is the resistor pack. You can buy these at an auto parts store for about $17. There is a panel on the passenger side of the car under the dash behind the center console (radio/HVAC area). Remove the panel and you will see what you need to replace. I've never done it but I hear that its about a 30 minute job.

As for the radio, I had to have mine replace under warranty because it too was cutting out. The wiring was bad INSIDE the radio. I definately don't think that the radio issue has ANYTHING to do with the HVAC stuff. You can purchase one of these radios on Ebay for pretty cheap...about $100 bucks.

As for the window, I would say the regulator is bad. You can also get these on e-bay for cheap.

I get the same noise from my brakes/rotors when they are wet. It's not so much a loud squeek, but a deep gurgle. Mine goes away after I make a few stops and the water gets off the rotors. I'm not sure if that's what your problem is, but I would say that the next time you need rotors, definately go after market. GM rotors suck on the N body.

Hope this helped.
