Can a defroster turn off the air conditioner?
Even when it comes on automatically, you still have a choice whether to leave it on. In my car, when the air conditioner comes on automatically as I run the defroster, I can turn off the air conditioner by pressing the air conditioner button. Even when it comes on automatically, you still have a choice whether to leave it on.
Why is my defroster not running in my car?
It’s not counterproductive. The AC removes moisture from the incoming air in order to keep the windows clear from fogging up. There are temps where the AC won’t run, the pressure switches and sensors will take care of that and turn off the compressor if the system is in danger of icing up.

Why does the air conditioner run cold when the heat is on?
When I turn on the defrost the AC runs, which at subzero temps is really counter productive and just plain cold. When you’re running both heat and the air conditioner, the air coming out of the vents should be hot, not cold. If, when you run both, the air is still cold, either the engine is too cold to warm…
Why does the defroster run warmer than the ambient temperature?
You have a compressor that takes a gas and converts it into a liquid. Then when that liquid is converted back into a gas at the evaporator, it’s released at a certain temperature. So, the temperature coming out the vents is warmer than the ambient temperature. People in the know in Minnesota do this if the AC system has a compressor button.

How does a faulty heater control valve affect cooling?
NOTE: The heater control valve is a directional valve. Make sure the water flow follows the direction of the arrow. As the engine heats up, the water transfers heat to the coil, thus overpowering the A/C coil. A leaking or faulty valve will have a more pronounced effect on the unit’s cooling ability.
