My aircon just packed in. It was working fine until I pulled in at a convenience store. When I returned to the car and started it up it was only blowing out warm air and its 35 degrees outside today. Not good. I turned it on and off a few times and then there was a loud thunk from behind the dash / engine room. Pressing the on / off button a few more times I got the same result. Then putting the car into drive and accelerating away I breifly heard a rattling noise. I have a feeling the compressor just broke but can't check for sure until I take it to the dealer. I'm afraid to drive it until then. The car is a 2008 model sedan with less than 40,000km. My last car (a Honda) never gave me any aircon problems and I racked up over 180,000km from new. What gives!? Has anyone else has this or a similar problem and what was the cause and fix?
