As a result the blower fan stays still and silent and no air blows out of the vents.
If you have faulty blower motor resist.
Without any power the motor won t run.
Power supplied from the fuse panel.
If a blower motor resistor test clears the resistor and the wiring the problem may lie in the fan s motor.
Symptoms of a bad blower fan motor resistor in this video we will explain the symptoms of a bad blower motor resistor.
This can be annoying but troubleshooting is easy.
As the fan speed is one of the most frequently adjusted settings of the air conditioning system the blower motor resistor is put under constant stress which can cause it to eventually fail.
Over the last ten years or so motor manufacturers have introduced more sophisticated heater blower resistors to control the blower fan motor for the heater and on many the digital aircon too.
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.
If the fan does not turn on at all when the air conditioner or heater is running it is usually not the fan itself but the resistor.
Since the blower resistor is directly responsible for transferring power from the battery to the blower itself a symptom of.
The heater resistor is also known as the resistor pack or rheostat.
The usual problems heater blower resistor and or connector.
The most common symptom of a faulty blower motor resistor is a blower fan that only works on one speed usually high.
The heater blower motor reduces or increases the amount of air blowing through the dashboard vents based on the fan speed selected or in an automatic climate control system the interior.
If you start at the blower motor and check resistance in the circuit you will find the problem in no time.
Order blower motor resistor for your vehicle and pick it up in store make your purchase find a store near you and get directions.
This symptom can also stem from a failed blower fan or several other issues.
