  Description and Operation  
 

The heater blower motor switch resistor has the following features:

  • The assembly is located on the passenger side of the plenum assembly behind the glove compartment.
  • Three resistance elements are mounted on the resistor board to provide four A/C blower motor speeds.
  • Depending on the heater blower motor switch position, series resistance is added or bypassed in the A/C blower motor circuit to decrease or increase A/C blower motor speed.
  • An overheating protective device (thermal limiter) will open the resistor coil circuit 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.
