Blower Motor Resistor What Is

The blower resistor is connected in series with 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.

Your vehicles blower motor resistor controls the speed of your blower motor.

Blower motor resistor what is. The resistor of the blower motor is responsible for transferring the electrical current thats required to move air through the vents of vehicle. If your system is still producing air however that does not mean your blower motor resistor is working correctly. Its used in cars where the blower motor has only 4 or 5 fixed speeds as on the left side in this diagram.

A blower motor resistor typically located beneath the passenger side dashboard contains three resistors or sets of terminals designed to generate voltage in proportion to electrical current. The blower motor no longer works correctly if this occurs. The blower motor resistor is an electrical component that is a part of the vehicles heating and air conditioning system.

There are several symptoms that appear when the resistor of the blower. The blower motor resistor is an electrical component that is a part of the vehicles heating and air conditioning system. These resistors allow the blower motor to function at lower speeds.

Blower motor resistors can wear out. When fan speed is changed via the knob on the instrument cluster the blower motor resistor changes. If your blower is stuck on a single setting.

The user chooses a suitable fan speed by using a selector to connect one of the resistors in the blower resistor pack. A blower motor resistor is an adjustable resistor. Since the blower motor and resistor are working almost constantly it can wear out over time.

See the photo of a ford blower motor resistor. Another indicator that you need a new blower motor resistor is an inability to use all of your available blower settings. It is responsible for controlling the blower motors fan speed.

This means that the current running through the blower motor and thus is speed is controlled by the resistor value. It is responsible for controlling the blower motors fan speed. This electric component is used to regulate a vehicles air conditioning system it is the part that controls the blower motors fan speed according to the settings which can be changed by using the knob and turning it left or right which would increase.

A blower motor resistor is a simple electric resistor.
