Where Is the Blower Motor Resistor Located?
Where Is the Blower Motor Resistor Located?The blower motor resistor controls the airflow from the HVAC ducts of older vehicles. When you turn the blower fan speed knob to change the setting, you direct the electric current through a path with different resistance. Lower speed settings have more resistance and reduce the power that reaches the

How to Test a Blower Motor Resistor
How to Test a Blower Motor Resistor(A burned out blower motor resistor connector) requires replacing the resistors as well as the resistor connector pigtail, but you need to do a really good job splicing the wires (and don’t get them out of order) or you’ll make bigger problems for yourself.–Richard McCuistian, ASE Certified Master Automobile Technician

What Is a Car Blower Motor? Purpose, Symptoms, and MoreThe blower motor is a critical part of your vehicle’s HVAC system. It is usually a permanent magnet, one-speed motor that operates at full battery voltage. The path that the current follows to the blower motor is typically controlled by the fan switch via a resistor pack (also known as
Where Is the Blower Motor Located?
Where Is the Blower Motor Located?Resistors can be found near the blower motor, sitting in the duct where airflow passes, so they can be cooled down because resistance in a current intensive circuit creates quite a bit of heat in the resistor. In this photo, you can see the blower and its resistor mounted in the
