FRONT
DESCRIPTION
The heater-A/C blower motor is controlled by a four position rotary-type blower motor switch, mounted in the 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.
OPERATION
The blower motor switch directs the blower motor ground path through the mode control switch to the blower motor resistor, or directly to ground through the high speed blower motor relay, as required to achieve the selected blower motor speed.
The blower motor switch cannot be repaired and, if faulty or damaged, the entire heater-A/C control unit must be replaced. The blower motor switch knob is serviced separately.
REAR
DESCRIPTION
The optional rear overhead A/C unit blower motor is controlled by a four position rotary-type blower motor switch, mounted by a snap fit in a hole in the headliner over the right front seat back. The switch allows the selection of one of three blower motor speeds and an Off position. The blower motor switch directs the blower motor ground path through the blower motor resistor.
OPERATION
The blower motor switch cannot be repaired and, if faulty or damaged, the entire switch unit must be replaced. The blower motor switch has a replaceable incandescent-type illumination lamp bulb.
