Getting hot air regardless if A/C is on or just fan or outside air or inside air. Temperature control and be on cold and the air is hot, if on hot then air is hotter. Not sure if a control issue, air actuater issue, thermostat. Any suggestions would be appreciated. Compressor is working and freon seems good.
The compressor appears to be working properly and yes the line is getting very cold.

I will check the clutch operation and compressor again tomorrow just to be sure.

DO YOU HAVE A MANUAL OR AUTOMATIC SYSTEM?

The temperature is controlled by the use of an air mix door that is operated by an electric motor/actuator. This door can be jammed or the actuator can be inoperative or have stripped plastic gears internally.
