A/C blend door or Control or or Temp control knob
I have a 2007 HHR 2.4. A/C works fine then intermittently starts blowing hot air. When this happens I can hear a change in the air coming from the vents and then the air gets hot. I can duplicate this condition by adjusting the temperature knob to about half way to heat. Also, sometimes turning it to full heat and back to full cool it will start cooling properly again. I am thinking the temp controller, [Cool/Heat] is failing causing this. Thanks.
The compressor continues to run when this is occurring.
