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.

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.
