Since I have had my Mazda 6 the aircon has never worked. When I turn the aircon on the revs jump and the fan kicks in, I think I can also see the clutch pulley engage, however, the air doesnt get cooler. I did think there was no refridgerant in the system but I always assumed there was a pressure switch on these systems that wouldnt let the system engage (ie no fan kicking in etc). I have also noticed that my Ambient temperature sensor is giving strange reading, 72 degrees when its about 5 degrees outside.
Any ideas?
Thanks
