HEATER AND DEFROSTER
On the lower roll of the instrument panel just to the right of the ignition switch are three knobs and two switches which control the heating, defrosting, and ventilation of the car.
HEATER AND DEFROSTER OPERATION
The operation of the heater and defroster controls is relatively simple by just remembering, heat goes up and cold goes down. Control up, maximum heat. Controls down, maximum outside air. The blowers are boosters under either set of conditions.
Left Hand Control
Up, regulates thermostat, the higher the warmer in-car temperature. Down, outside air for ventilation. The farther down the greater the amount of air. Switch (at top) operates underseat heater. Heats floor, particularly rear. Air circulation is summer. Has high and low position.
Center Control
Up, regulates amount of air to windshield for defrosting or cooling. For maximum defrosting winter range control should be in full up position. Switch, above Auxiliary Vent Control (R. H. knob) acts as booster for low car speeds, or when parked.
Right Hand Control
Up, allows outside air to enter through auxiliary hater, mounted at right hand kick pad, onto front floor. May be used for heating and de-fogging in winter. Must be down when defroster (center control) is up. However, may be used proportionately with defroster. Down - Outside air for ventilation. The farther down the greater the amount of air. May also be used in winter to provide air for defrosting when outside air intake is plugged with ice or snow. 
Switch (at top) operates auxiliary heater for motor. Provides air flow when parked or at low car speeds to defroster, lower floor level or both depending on position of center and right hand controls.
