Front Control Switch
CIRCUIT OPERATIONWhen the front control switch is in the LOW position, ground passes through the temperature switch, and both resistors to circuit C60. Circuit C60 connects to the front control switch. The front control switch connects the blower motor to ground on circuit Z1.
When the front control switch is in the MEDIUM position, ground passes through the temperature switch, and one resistor to circuit C65. Circuit C65 connects to the front control switch. The front control switch connects the blower motor to ground on circuit Z1.
If the front control switch is in the HIGH position, the ground path for the blower motor is on circuit C70 through the front blower switch to ground circuit Z1.
