Where is the fan motor resistor?

Where is the fan motor resistor?

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.

How do you know if a fan resistor is bad?

Bad Blower Motor Resistor Symptoms

1. Only One Speed From Blower Motor. One of the most common symptoms of trouble with the blower motor resistor is when the fan gets stuck in one setting.
2. Various Airflow Settings Not Working.
3. No Air Coming From Vents.

Is a fan motor a resistor?

The blower motor resistor is responsible for controlling the blower motor speed. Each fan speed selection is connected to one or more of the resistors in the blower resistor assembly. The change in resistance controls the current through the blower motor, which in turn limits the speed that the blower motor spins at.

How do I know if my blower motor resistor is bad or blower motor?

If the airflow from the vents is weak… If you try to increase the air pressure and you feel no difference in the pressure blowing, then your blower motor resistor may be failing. A damaged blower motor resistor will work on one fan speed which may not be enough to keep the inside of your car cool or warm enough.

Will a blower motor work if the resistor is bad?

There are instances where a bad resistor will prevent the current from reaching the blower motor altogether. Without any power, the motor won’t run. As a result, the blower fan stays still and silent, and no air blows out of the vents.

How do you test a fan resistor?

Place one lead of the Ohmmeter on terminal 1 of the resistor. Place the other lead on terminal 2 and check against specifications. If this circuit is open, showing infinity on the Ohmmeter, the blower resistor must be replaced. Move the lead from terminal 2 to terminal 3 and check this reading against specifications.

What happens when the blower motor resistor goes out?

If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed. The heating and air conditioning systems may still function at one speed, however the resistor will have to be replaced in order for full functionality to be restored.

What does the blower motor do on a Nissan Alero?

The blower motor in the Alero provides power to your air conditioning and heating system. Since the Alero was never redesigned, replacing the blower motor will be the same between year models. Make sure you are parked in a well-lit area.

What is an Oldsmobile Alero?

The Alero was a mid-sized car build by General Motors and sold under the now discontinued Oldsmobile brand. The Alero was built in the same factory as the Pontiac Grand Am and shared all of its mechanical components with the Grand Am. The Alero was produced between 1999 and 2004.

What kind of motor does a Pontiac Alero have?

The Alero was built in the same factory as the Pontiac Grand Am and shared all of its mechanical components with the Grand Am. The Alero was produced between 1999 and 2004. The blower motor in the Alero provides power to your air conditioning and heating system.
