Blower Motor
| Refer to COMPONENT INDEX . |
The blower motor produces the air flow throughout the HVAC system. The volume of air can be varied by changing the speed of the blower motor using the integral blower motor power module. In the Automatic Temperature Control (ATC) HVAC system, the blower speed can be controlled by the HVAC module when in AUTO mode, or it can be controlled by the operator's input via the blower control switch in the A/C heater control or using the blower control in the radio (if equipped).
The blower motor is used to control the velocity of air moving through the distribution housing by spinning the blower wheel within the air inlet housing at the selected speed. The blower motor is a 12-volt, Direct Current (DC) motor mounted within a plastic housing with an integral wire harness connector and three mounting tabs. The squirrel cage-type blower wheel is secured to the blower motor shaft and is positioned within the air inlet housing on the passenger side of the HVAC housing.
