Land Rover Part Number: STC3133 - Blower Resistor Pack - Heater
STC3133 is a Blower Resistor Pack - Heater. Fitted to the heater and air conditioning blower assembly, it provides stepped speed selection for the heater blower motor and allows the fan to run at the selected blower speeds from the vehicle controls.

Frequently Asked Questions
STC3133 regulates the stepped fan speeds for the heater blower motor inside the heater and air conditioning blower assembly, allowing selection of multiple fixed blower speeds from the dashboard controls. A failing resistor pack commonly results in loss of some speed settings or intermittent blower operation, and replacing the unit restores normal stepped speed control on compatible vehicles.
