Blower Motor Resistor: Description and Operation
BLOWER MOTOR RESISTORThe blower motor resistor:
- is located on the heater core and evaporator core housing near the blower motor.
- has 3 resistor elements mounted on the resistor board to provide 4 blower motor speeds.
- depending on the blower motor switch position, series resistance is added or bypassed in the blower motor circuit to decrease or increase blower motor speed.
