Blower motor fan resistor.

A blower motor resistor or a blower motor control module is the part that controls the speed of the blower motor. When it fails usually due to corrosion or overheating you may notice a few things. Symptoms of a bad blower fan motor resistor in this video we will explain the symptoms of a bad 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 motor s fan speed. What does the blower motor resistor do. It s located inside the dash often on the opposite side of the steering wheel or inside the engine compartment on the firewall. 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.

The blower motor resistor is an electrical component that is a part of the vehicle s heating and air conditioning system. 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. The motor that runs the fan in the heating and air conditioning system in a car is called a blower motor. Air flows but only at high speeds and other settings no longer work.

A sure fix requires trusted parts. Blower works on all settings. Get it as soon as thu sep 24. 40 cheaper than advanced auto.

4 5 out of 5 stars 69. It accomplishes this by regulating the electric current that powers the motor. Since the blower motor and resistor are working almost constantly it can wear out over time. The blower resistor is connected in series with the blower fan.

Hvac blower motor fan resistor g023r for dodge ram 1500 2500 3500 pickup jeep grand cherokee grand wagoneer replaces 4720278 973020 68004241aa 5012212aa by gohawkteq cheap easy to install by jonathan sandoval easy installation on 2001 dodge ram 2500. 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. Your vehicle s blower motor resistor controls the speed of your blower motor. The user chooses a suitable fan speed by using a selector to connect one of the resistors in the blower resistor pack.

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.
