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 rear HVAC housing at the selected speed.


The rear blower motor will only operate when the ignition switch is in the On position 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 the On position.


For diagnosis and testing of the rear blower motor, refer to Blower Motor testing.


The rear blower motor and blower wheel are factory balanced and cannot be adjusted or repaired. If faulty or damaged, the blower motor and blower wheel must be replaced as an assembly.
