The detent in my A/C-Heater selector switch failed. The knob moves smoothly except in OFF. Everything still works fine.
I have been trying to search for a new selector without success. What is the part number and what is it called? The car has factory AC.

If I can't find a replacement, I will have to try to repair the old one.

That’s the head unit. I’m not exactly sure if that’s what you are after, a picture may help here.

Unfortunately I don’t believe that part is made anymore. My google results have turned up pretty empty. It’s called a mode door switch on most cars, although google searches have come up with a damper door switch as well.

Can you get the part number off the switch?

I'm 95% sure the parts, or the entire thing is interchangable.

The 1986 Taurus also came with the same setup as the 87-89 HVAC controls, if anyone is ever looking for parts for that one
