Blower Motor Resistor

The blower motor resistor:

• is located on the evaporator core housing behind the glove compartment.
• 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.
• has an overheating device (thermal limiter) that will open the resistor coil when the temperature reaches approximately 184°C (363°F), interrupting the blower motor operation in all speeds except high.
• is replaced as an assembly. The thermal limiter cannot be reset and cannot be repaired.
