Default ac compressor going on

I replaced my motor and know my ac compressor goes on everytime I turn on my heat, defrost, or ac. Can anybody tell me why this is going on whenever I turn on the heat or defrost, also I am not getting any air out of my dash vents.

Default

The AC compressor is supposed to run when in either AC mode, defrost, and bi-level modes. It runs regardless of the temperature control.

If you have no airflow from the vents, plug the HVAC source vacuum hose back into the rear of the intake.
