You can control when the A/C clutch is engaged or not by pressing the snowflake button on the HVAC control head. It does not matter if the temp is set to cold or hot.

Also, if you have the mode set to defrost the compressor will run regardless whether the A/C button has been pressed or not because the purpose of A/C is to remove the humidity from inside the cabin.
