Im having trouble with my a/c system blowing cold air. System checks out mechanically ok and everything is working as it should. However there is no cold air blowing in cabin of car. I assume there is some sort of climate control that regulates the temperature in the cabin? Any help greatly appreciated.

how did you verify the system is working properly?
manifold gauges, feeling the high and low sides hoses?




if you are confident the problem is on the air delivery side. the first check is to verify the temp blend door is working. when you move the control **** you should hear a change in airflow are the door moves....you can also locate the blend door actuator and watch it move.


the system has full diagnoistics. with a scan tool check for body codes. with a scan tool, you can also watch the door position counts change as the blend door moves.
