Ac Heater Blower Motor Fan Speed Control Resistor

The change in resistance then limits the current through the motor which dictates the speed at which the blower fan works.

Ac heater blower motor fan speed control resistor.

The heater blower resistor helps control the rate at which the blower motor supplies this air. Blower motor resistor test if you can hear the blower fan running but can t make it change its speed you probably have an issue with its resistor. A common symptom of a faulty blower motor resistor is a blower motor that is stuck on one setting. This truck has auto climate control but also has a manual fan switch.

Blower motor stuck on one speed. Since the blower motor and resistor are working almost constantly it can wear out over time. I have a 2006 ford f350 super duty king ranch that the heater ac fan only works on high. The blower motor resistor is the component directly responsible for controlling the blower motor fan speed.

It is responsible for controlling the blower motor s fan speed. The fan speed can be changed either by switching the blower resistor resistance mechanically using a rotating lever or electronically by the air conditioning system. If your car s blower has only 4 or 5 different speed settings it likely uses a simple electric resistor to control the fan s speed.

There is no fan motor resistor as some pe read more. Unfollow blower motor fan speed resistor to stop getting updates on your ebay feed. 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 vehicle s blower motor resistor controls the speed of your blower motor.
