The A/C does not blow cold air. We took it to Firestone and they said it was fine. We mentioned that we thought the A/C control unit connected to the head unit might be the issue. We got home and updated the HU software. Still not working. We plugged back in the old A/C control unit plug and disconnected the digital one. Still not cold air. The A/C turns on and blows. The compressor belt engages and spins the compressor. The A/C seemed to quit after we changed out the battery, but could be coincidence. What worried me was the ac control unit was turning on by itself and even blowing hot air early on. Lit the heater wanted to run. We are taking it back to Firestone as a double check. Is there a was to test the cold air bypassing the AC/heat unit? Like unplug it. Or test the computer? Thanks Henry
