Rear

The rear blower motor (1) and blower wheel (2) is located in the rear HVAC housing behind the right interior quarter panel trim and is connected to rear HVAC wire harness by a integral wire harness connector (3). The rear blower motor controls the velocity of air flowing through the rear HVAC housing by spinning the wide squirrel cage-type blower wheel within the HVAC housing at the selected speed. Rear blower motor speed is controlled by regulating the ground path through the rear blower motor switch and the rear blower motor resistor block.

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.

The rear blower motor, blower wheel, and blower wheel housing cannot be repaired and, if faulty or damaged, they must be replaced as an assembly.
