Blower Motor Switch: Description and Operation
The A/C Heater blower motor is controlled by a four position rotary-type blower motor switch, mounted in the A/C Heater control panel. The switch
allows the selection of one of four blower motor speeds, but can only be turned OFF by selecting the OFF position on the blower motor switch.
The blower motor switch directs the blower motor ground path through the mode control switch to the blower motor resistor, or directly to ground, as
required to achieve the selected blower motor speed.
The blower motor switch cannot be repaired and, if faulty or damaged, the entire A/C Heater control unit must be replaced.
