Temperature Control Knob
When the temperature control knob is in the "COLD"
position, the air mix door closes to block the flow air to the
heater core.
When the temperature control knob is in the "HOT"
position, the air mix door opens to allow air to pass
through the heater core and heat the passenger
compartment.
Placing the knob in a intermediate position will cause a
lesser or greater amount air to reach the heater core. In
this mode the passenger compartment temperature can
be regulated.
