I've had issues getting heat or A/C to my car's cabin. I've checked the heater core and it seems to have good flow. I've replaced the thermostat and the blower motor still pushes air. What else can I try with my temperature control knob "stuck" (by stuck I mean it turn with pliers but eventually returns back to original position. Could this knob be my only issue? What else could it be?
