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.
