Re: 75 k20 air and heat controls?
you basically have the switch for the fan the cable for blend door and the other part is a vacuum selector if im not mistaken. gm had the same hvac unit up until the late 80s. oh theres a contact for the ac to kick on in there too in on the vacuum selector knob itself. its just contacts iirc.
