I parked my car and the a/c was working, came back 45 mins later, started the car and the a/c was blowing hot air. I went to two a/c men who checked the which was ok and ran a direct wire to the compressor which worked.There is no current going to the compressor, all the fuses were ok what is the problem ?
If the refrigerant is low the compressor will not switch on
SOURCE: fan not blowing hot or cold air into car
Sounds to me like your heater resistor may be bad do you have any speeds on the fan because typicly you will still have high when this fails if so you may want to check fuse for heater and relay hope this helps

change the battery but first check the dynamo and car starter
If you touched any of the A/C controls within 45 seconds of starting your Suburban (after the battery change), you messed up the 'calibration mode' of the HVAC.
Pull the HVAC fuse (10amp) under the hood, and pull the two adjacent fuses (30 and 10amp) under the dash listed as 'climate control' in the manual.
Push the fuses back in, restart your car, but DONT TOUCH ANY of the A/C controls for 90 seconds.
I bet the A/C starts working again normally.
