Car is blowing hot air on all settings. I've pulled under-dash panel from passenger side and the hose (metal pipe) going to the blower is cold, and I can hear the compressor kick-in when I turn on the a/c. I've checked the thermistor, on top of the dash, it is getting vacuum and the wiring is connected. Any ideas on what may be wrong?
