The 2012 Ford Fusion blower motor resistor is a crucial component responsible for controlling the speed of the vehicle's heating and air conditioning system. Understanding its function, symptoms of failure, and replacement process is essential for maintaining optimal climate control in your vehicle.

Overview of the Blower Motor Resistor

The blower motor resistor regulates the voltage supplied to the blower motor, allowing it to operate at different speeds. When this component fails, drivers often experience issues such as:

  • The blower motor only functioning at high speed
  • Inconsistent operation of the blower motor
  • Complete failure of the blower motor

These symptoms indicate that the resistor may need replacement.

Replacement Process

Replacing the blower motor resistor in a 2012 Ford Fusion is a straightforward task that can be performed by those with basic mechanical skills. Here’s how to do it:

Tools Needed

  • 7 mm socket or 7/32 socket
  • Ratchet and extension
  • Screwdriver

Steps for Replacement

1. Access the Resistor:

- The blower motor resistor is located under the passenger side dashboard, near the blower motor.

- Remove the glove box for easier access if necessary.

2. Remove the Old Resistor:

- Unscrew the single screw holding the resistor in place.

- Disconnect the wiring harness from the resistor.

- Carefully wiggle and pull out the old resistor from its housing.

3. Install the New Resistor:

- Insert the new resistor into the housing.

- Reconnect the wiring harness securely.

- Fasten it with the screw you removed earlier.

4. Test Functionality:

- Start your vehicle and test the blower motor at various speeds to ensure proper operation.

Common Issues and Considerations

When replacing the blower motor resistor, it's important to consider potential underlying issues:

  • Overheating: If your resistor has failed due to overheating, it may be a sign that your blower motor is drawing too much current. In this case, consider replacing both components to prevent future failures.

  • Connector Damage: Inspect the electrical connector for signs of melting or damage. If found, replace it along with the resistor to ensure reliable operation.

Cost of Replacement

The average cost for replacing a blower motor resistor in a 2012 Ford Fusion ranges from $54 to $71, including labor costs between $26 and $33. Parts are typically priced between $27 and $38, making it a relatively affordable repair option compared to other automotive repairs.

FAQs About 2012 Ford Fusion Blower Motor Resistor

    • How do I know if my blower motor resistor is bad?
      If your blower only works on high speed or not at all, it's likely that the resistor has failed.
    • Can I replace the blower motor resistor myself?
      Yes, with basic tools and mechanical skills, you can replace it yourself.
    • What causes a blower motor resistor to fail?
      Common causes include overheating due to excessive current draw from a failing blower motor.

Understanding these aspects will help you maintain your 2012 Ford Fusion's climate control system effectively and efficiently.
