Blower Motor Switch: Description and Operation
Blower Motor Switch
The heater-only or 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.
The blower motor switch receives ignition-switched battery current through the mode control switch from a fuse in the fuseblock module. The
blower motor switch directs the battery current to the blower motor resistor, or to the blower motor relay, as required to achieve the selected
blower motor speed.
The blower motor switch cannot be repaired and, if faulty or damaged, it must be replaced. The blower motor switch knob is available for service
replacement.
