Blower Motor Resistor

The blower motor resistor has the following features:

• The assembly is located in the passenger compartment on the heater core and evaporator core housing next to the blower motor assembly.
• 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.
• An overheating device (thermal limiter) will open the resistor coil when the temperature reaches 121°C (250°F) interrupting the blower motor operation in all speeds except HIGH.
• The thermal limiter cannot be reset and is not serviceable
