Since you get cold air, the A/C is most probably working (assuming you are lucky enough to be in a place where it's warm - I woke up to 2 degrees F this morning!).

It's the ACC system that determines how much heat or cold to produce. I recommend you run a self-test/recalibration on the ACC. Simply hold down the AUTO and VENT (bottom right) buttons at the same time for a few seconds - you'll see the system start to march through a self-test. Release the buttons and wait.

If it pops up with a '0', no faults were found. Any number other than zero means faults were found, and it will take a dealer or technician with a Tech II to read the codes. HOWEVER, sometime the ACC system just needs a recalibration, and the self-test does that.

Assuming there is a problem, what could be wrong? It could be a bad cabin temperature sensor - it thinks the cabin is cold, so it won't turn on the A/C unless you select Low. There is a little bulls-eye grill in the dash - that's the cabin temp sensor. After the car has been started and run, shut off the car and listen at that little grill. You should hear a fan running (it runs for a few minutes after the car is turned off). That fan is pulling cabin air in over the sensor. If you don't hear it running, the sensor has a problem. However, a fan failure would usually result in colder than normal temps.

A long post, but most likely the re-calibration will fix things.
