It's connected through a cable to either the door is jammed or the cable is jammed.

This is not the hot cold lever. That works fine. It is the upper lever that turns on the A/c or the heater or defroster. It moves just a little bit than stops !

That should be a rotary vacuum switch. You will have to pull out the control assembly and see what the problem is.
