Blower motor fan resistor.

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. The user chooses a suitable fan speed by using a selector to connect one of the resistors in the blower resistor pack. Hvac fan blower motor resistor replacement for 1994 2008 dodge ram 1500 2500 3500 pickup 1993 1999 grand cherokee replaces ru109 973020 4720278 68004241aa 68004539aa 5012212aa hvac fan resistor. When it fails usually due to corrosion or overheating you may notice a few things.

Your vehicle s blower motor resistor controls the speed of your blower motor. The blower resistor is connected in series with the blower fan. Another indicator that you need a new blower motor resistor is an inability to use all of your available blower settings. Since the blower motor and resistor are working almost constantly it can wear out over time.

It s located inside the dash often on the opposite side of the steering wheel or inside the engine compartment on the firewall. A blower motor resistor or a blower motor control module is the part that controls the speed of the blower motor. A sure fix requires trusted parts. 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.

4 5 out of 5 stars 69. Blower works on all settings. It accomplishes this by regulating the electric current that powers the motor. 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.

Get it as soon as thu sep 24. What does the blower motor resistor do. 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. Symptoms of a bad blower fan motor resistor in this video we will explain the symptoms of a bad blower motor resistor.

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

It is responsible for controlling the blower motor s fan speed.
