Blower Motor Resistor: Description and Operation
BLOWER MOTOR RESISTOR
The blower motor resistor has the following features:
-
The assembly is located in the engine compartment on the evaporator housing toward the center of the vehicle
-
Three resistor elements are 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
-
A device to prevent overheating (thermal limiter) will open the resistor coil when the temperature reaches 121°C (250°F) interrupting the blower
motor operation in all speeds except HI
-
The thermal limiter cannot be reset and is not serviceable
