Front

The front blower motor is controlled by a four position rotary-type blower motor switch, mounted in the heater-only or heater-A/C 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 with the heater-A/C mode control switch knob.

The blower motor switch directs the blower motor ground path from the mode control switch to the blower motor resistor, or provides a ground directly to the high speed blower motor relay, as required to achieve the selected blower motor speed.

The front blower motor switch cannot be repaired and, if faulty or damaged, the entire heater-only or heater-A/C control unit must be replaced. The blower motor switch knob is serviced separately.
