Heater Fan Resistors

• Heater fan resistors are responsible for varying the current flow to the interior blower motor.
• The heater fan resistor is a common failure point within the heating and air conditioning system. This is due to excessive heat cause by the loads the resistor introduces.
• Early styles of heater fan resistors generally were a resistor pack consisting of wound wires varying in gauge. Later styles include transistors utilising printed circuit boards
• The Tridon heater fan resistor range has been carefully researched and compiled to replace each specific application.
• As heater fan resistor internal specifications may vary; always refer to the Tridon vehicle application list to ensure correct part number selection.
