DESCRIPTION
The air conditioning evaporator housing is
mounted to the bottom of instrument panel. The
evaporator, blower motor, thermostat, and expansion
valve are located in the evaporator housing. The com-
pressor, condenser, receiver-dryer and refrigerant
lines are located in the engine compartment.
The heater housing is mounted to the dash panel
behind the instrument panel.

has 2 functions. It attaches the cable to the vent door
and is also the self adjusting mechanism. The left ca-
ble operates the right cable. The cables must be in-
stalled as outlined to maintain the self adjusting
feature and ensure proper vent door operation.
