I've performed over a dozen of the bluetooth, XM, Sirius installs..and never had a problem. My AC controls work fine, the sirius works fine, bluetooth, car runs fine..etc...but the fan isn't blowing air....I've only had the car for 3 weeks...but if the $64 resistor is all I need to fix it.....I don't mind an hour worth of work.....hell I can't find a service center open right now and I'd prefer to fix it then get a loaner car for 2 days....
