Blower Motor Fan Resistor

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.

Blower motor fan resistor.

What does the blower motor resistor do. The blower resistor is connected in series with the blower fan. It s located inside the dash often on the opposite side of the steering wheel or inside the engine compartment on the firewall. Air flows but only at high speeds and other settings no longer work.

When it fails usually due to corrosion or overheating you may notice a few things. 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. 4 5 out of 5 stars 69. Blower works on all settings.

This means that the current running through the blower motor and thus is speed is controlled by the resistor value. If you have faulty blower motor resist. 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. 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.

A blower motor resistor or a blower motor control module is the part that controls the speed of the blower motor. The user chooses a suitable fan speed by using a selector to connect one of the resistors in the blower resistor pack. 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 blower motor resistor is an electrical component that is a part of the vehicle s heating and air conditioning system. 40 cheaper than advanced auto. Another indicator that you need a new blower motor resistor is an inability to use all of your available blower settings. A sure fix requires trusted parts.

Get it as soon as thu sep 24. Since the blower motor and resistor are working almost constantly it can wear out over time. 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.

It accomplishes this by regulating the electric current that powers the motor.
