AC actuator module controls air blend door, and vent system. Probably is bad. As long as your temperature gauge is reading around 200 deg. if not it would be the thermostat.

Check your coolant level first. It's probably low.

mine does the same thing and now the blower doesnt work...sometimes. we had the thing flushed out and it fixed it for a day any tips? or ideas of how to fix this?

The blower is likely a failed resistor in the heat duct. That's a separate issue from the lack of heat. Check your coolant level first. If its low fill it up and the problem will likely go away.
