What is a Blower Resistor?

Blower resistors are resistors which are used to control the fan speed of automotive blowers. The fan speed can be changed either by switching the blower resistor resistance mechanically using a rotating lever, or electronically by the air conditioning system. The change in resistance then limits the current through the motor, which dictates the speed at which the blower fan operates. A failed blower motor resistor can cause your car's fan to stop working completely.

Construction：

Blower resistors, being a mechanical component, are prone to wear and are the most common point of failure in a car’s heating system.

How to diagnose a blower fan motor?

• Check the fuse for power on both ends using a multimeter. If there is power on one end of the blower fan fuse but not the other, then the fuse needs to be replaced.
• Check the fan relay. Such relays can be tested by placing a finger on them and switching the fan’s control on and off. Clicking from the relay is an indication that the relay is almost certainly working correctly.
• Check the fan itself for power presence by turning on the fan control and checking the fan itself with your multimeter. If there is no power present at the fan, suspect a wiring fault. If power is present on the fan’s terminals and the fan is not working, the blower fan is defective.
• Once the resistor is located and detached, it is often possible to say whether the resistor has burned out or not judging by the physical appearance only.

• If the appearance is normal, it is necessary to measure the resistance across each individual resistor. If any of these resistances show an open circuit (infinite resistance), then the blower resistor needs to be replaced.
