Replaced temperature knob several times until the shaft actually broke. Needs new unit to fix. Have not done it yet, requires removing nearly the whole dashboard from what I was told.

when your heater control knob breaks,, go to the parts store and find a hose clamp the same size and put it on the back of the know where it sticks out.. fixed !!
My fan speed knob broke. Still need the part. Currently using pliers. They work fine though.

heater temperature knob spins freely, heat stuck on full. Not fixed yet - does the whole dashboard have to come off?
