Rear Air Conditioning Resistor Assembly for the rear blower (HVAC) circuit on vehicles equipped with rear air conditioning.

The resistor pack sits in the rear blower motor feed and sets the lower fan speeds by introducing resistance into the motor circuit, dropping the voltage supplied to the rear blower motor. The selected speed is determined by which resistor element the current passes through.

Frequently asked questions

What does the STC3816 rear A/C resistor assembly do?
The STC3816 rear A/C resistor assembly sets the lower fan speeds for the rear air conditioning blower on the Discovery 1. It sits in the rear blower motor feed and drops the voltage supplied to the motor by adding resistance, so the selected speed depends on which resistor element the current passes through.
Where is the STC3816 resistor located on the vehicle?
The STC3816 resistor sits in the rear blower (HVAC) circuit on Discovery 1 models fitted with rear air conditioning. It's wired into the rear blower motor feed, typically positioned near the rear blower housing where airflow helps dissipate the heat it generates.
Why does the rear A/C resistor fail on a Discovery 1?
The rear A/C resistor typically fails from the constant heat it dissipates, which can burn out one or more resistor elements over time. The usual symptom is losing the lower rear fan speeds while the highest speed still works, since top speed often bypasses the resistor pack.
Will the STC3816 resistor fit my Discovery 1?
The STC3816 fits the Land Rover Discovery 1 (1989-1998) equipped with rear air conditioning, VIN FA393361 to WA799999. Vehicles without rear A/C don't use this resistor. Check your VIN and confirm rear air conditioning is fitted before ordering.
