The blower switch, heat and AC all work, but the mode control knob seems to be stuck in one position and air comes from the defrost vent, dash and floor all the time. It does not matter what position I put the control knob in, the air flow never changes.

I have checked all fuses and they were fine.

Any thoughts?

Thanks,
Carl

You may want to check the mode door actuator; down on the side of HVAC case; some models have linkage that breaks and falls off
