I'm driving down the road to work and all of a sudden the Air Con starts blowing out hot air as if I had turned on the heater. To double check myself I fiddle with the controls with no avail. First thing I check is the fuses. BINGO... so I thought. I replace the fuse and still no cold air. Now I'm scratching my head and proceed to look at the actual compressor. Ok, compressor is spinning. Still no cold air. Next I think well maybe the "freon" is had evac't somehow. Hit the shrader valve and got blasted with refrigerant. Now if I remember from HVAC school "freon" doesn't just go bad, there has to be some sort of leak which in turn allows it to evac into the environment. So with that being said there's def pressure in the system meaning it hasn't leaked. So this leads me to my last and final thought that it may be some sort of temp sensor that has to do with the climate control system in the car. This car is WAY beyond me considering it's closely related to the X-Type Jaguar which should of threw up a flag when I bought it :violent1:. Any suggestions from the SN95Forum Elite?!</blockquote>
