BLOWER MOTOR KNOB 

Located in the A/C control panel, the blower motor knob controls blower motor speed in 4 settings. See Fig. 1 . 
The blower motor knob sends a voltage signal through the blower motor resistor in "1" to "3" positions and by-
passes blower motor resistor in position No. 4. See WIRING DIAGRAMS . Setting blower motor knob to "0" 
position will turn system off.

detents in-between to adjust airflow for personal comfort. 

Defrost 

Set mode control knob to 12-o'clock position. Air will exit from defrost outlets and side window vents. 

Vent

Set mode control knob to 3-o'clock position. Air will exit from defrost, instrument panel, and floor outlets. 

TEMPERATURE CONTROL KNOB 

Air temperature is controlled by a variable resistor rotary control switch. See Fig. 1 . Switch receives voltage 
signal and depending upon position, controls voltage signal sent to air mix damper door motor. See Fig. 2 . 
Voltage controls position of motor for heating and cooling.
