Exclamation AC Cold air Not Working!!

Greetings,
Started my 2011 JK and found that air conditioning is not working with cold air, It is always blowing heated air, not matter where I move the temp. controller knob !!!
I verify the compressor and it is engaged. Any recommendations?

Blend door or leak in the system/no refrigerant.

I agree with above. If it is definitely heated air and not ambient air the blend door isn’t working. A bandaid would be to shunt the heater core. If it’s February and you want ac you probably don’t need heat. If air isn’t moving across the evaporator correctly I would be hesitant to use the ac because you can slug the compressor and the bill can add up
