BLOWER MOTOR RESISTORS AND SPEED CONTROL
HEATER BLOWER MOTOR RESISTORS
The heater resistor is also known as the heater blower motor resistor because it fundamentally controls the fan speed of the interior heater.
The VOLT range covers both traditional resistor based controllers (which typically feature 4 speed settings) and modern electronic speed controllers used in vehicles with more advanced automatic climate control systems.
PRE-RESISORS (RADIATOR FAN RESISTORS)
The pre-resistor controls the speed of the radiator/cooling fan. Using information from the coolant temperature sensor, the vehicle activates the cooling fan when needed. Power to the fan is routed through a pre-resistor, which allows the vehicle to control the speed of the fan depending on the temperature of the engine. An increase or decrease in resistance effects the voltage though the motor, resulting in the required changes to fan speed.
RESISTOR CABLE REPAIR KITS
A selection of connector/cable repair kits are available to support the range of heater/blower and fan/radiator resistors. Connectors and cables damaged by overheating are often the cause of the resistor and blower/fan not functioning. Equally, a failing resistor can cause damage to wiring and connectors. It is important to test both the resistor and the connection before replacing either component.
VEHICLE PERFORMANCE GUARANTEE
VOLT branded component testing ensures operation within the manufacturer’s original parameters. This guarantees no change to the vehicles original performance.
OE MATCHING PERFORMANCE
VOLT components deliver original equipment matching performance. Sensible pricing and extra support services add value to the VOLT Range.
