Blower Motor: Description and Operation
Operation - Rear
OPERATION
The rear blower motor is used to control the velocity of air moving through the rear HVAC housing by spinning the blower wheel within the HVAC
housing at the selected speed.
The rear blower motor will only operate when the ignition switch is in RUN and the front A/C-heater control is set to either front control of rear
heating-A/C system or to the rear control of the rear heating-A/C system. The rear blower motor receives a battery feed through the rear blower motor
relay located in the power distribution center (PDC) whenever the ignition switch is in RUN.
The rear blower motor and blower wheel are factory balanced and cannot be adjusted or repaired and must be replaced as an assembly if found
inoperative or damaged.
