Blower Motor Fan Resistor

The blower motor resistor is an electrical component that is a part of the vehicle s heating and air conditioning system.

Blower motor fan resistor.

Blower works on all settings. A sure fix requires trusted parts. 4 5 out of 5 stars 69. It s located inside the dash often on the opposite side of the steering wheel or inside the engine compartment on the firewall.

Another indicator that you need a new blower motor resistor is an inability to use all of your available blower settings. The motor that runs the fan in the heating and air conditioning system in a car is called a blower motor. If your blower is stuck on a single setting or has some settings on which it is non operational that means your blower motor resistor may be broken. When fan speed is changed via the knob on the instrument cluster the blower motor resistor changes setting which changes the speed of the blower motor.

A blower motor resistor or a blower motor control module is the part that controls the speed of the blower motor. Get it as soon as thu sep 24.

Air flows but only at high speeds and other settings no longer work. Your vehicle s blower motor resistor controls the speed of your blower motor. Symptoms of a bad blower fan motor resistor in this video we will explain the symptoms of a bad blower motor resistor. It is responsible for controlling the blower motor s fan speed.

What does the blower motor resistor do. The user chooses a suitable fan speed by using a selector to connect one of the resistors in the blower resistor pack. This means that the current running through the blower motor and thus is speed is controlled by the resistor value. The blower resistor is connected in series with the blower fan.

The blower motor resistor is a single part often with several possible pathways for current flow that provide more or less resistance depending on the demand from the dash setting. Since the blower motor and resistor are working almost constantly it can wear out over time. 40 cheaper than advanced auto. The resistor controls the fan speed of the blower motor and the resulting change in air pressure produced by the movement of the blower fan.

When you turn a knob to produce more air flow for heat or cool air the resistor adjusts the electrical resistance to control the power sent to your blower motor.
