Power running boards are a popular upgrade for vehicles, especially trucks, SUVs, and large off-road vehicles. These automated steps, often hidden beneath the vehicle’s frame, deploy when the door opens, providing an easier step for entering and exiting the vehicle. A critical component of this system is the power running board motor, which operates the mechanism that extends and retracts the running boards.

What Is a Power Running Board Motor?

The power running board motor is an electric motor responsible for activating the running boards in a vehicle. When the vehicle's door is opened, the motor triggers a series of mechanisms that deploy the running boards, allowing passengers to step in and out of the vehicle more easily. Once the door is closed, the motor reverses the mechanism, retracting the boards into their hidden position.

This system is particularly useful in larger vehicles, which can have higher ground clearance, making entry and exit more challenging for individuals with mobility difficulties.

How Does a Power Running Board Motor Work? The process behind the power running board motor is relatively simple but involves several components working in unison:

Activation: When the vehicle’s door opens, a sensor or switch is triggered, signaling the power running board motor to engage.

Motor Function: The electric motor then powers the running board assembly, deploying the board from its stowed position beneath the vehicle.

Deployment: The running board moves outward, usually supported by a set of hinges and mechanical linkages.

Retraction: When the door is closed, the process reverses. The motor retracts the board into its hidden position under the vehicle, out of sight and protected from damage.

Key Components of a Power Running Board Motor System A typical power running board system consists of several key components that work together to provide smooth operation:

Electric Motor: The heart of the system, this motor provides the force necessary to deploy and retract the running boards.

Control Module: This electronic unit manages the operation of the running boards, including when to deploy or retract based on the door's position or other factors.

Linkages and Hinges: These mechanical components facilitate the movement of the running board, ensuring that it extends and retracts properly.

Sensors: Often built into the door or the vehicle's control system, these sensors detect when the door is open or closed, sending signals to the control module to activate the motor.

Power Supply: The motor is powered by the vehicle’s battery, usually drawing power through a dedicated circuit.

Benefits of Power Running Board Motors Enhanced Accessibility: The most obvious benefit of power running boards is improved accessibility. They provide an easy step for entering and exiting high vehicles, especially for children, elderly people, and those with mobility issues.

Convenience: Since the running boards automatically deploy and retract with the opening and closing of the doors, users don’t need to manually adjust them.

Improved Aesthetics: Power running boards remain hidden when not in use, maintaining the sleek look of the vehicle. This is a significant advantage over traditional fixed running boards, which are constantly visible.

Durability: Modern power running board motors and systems are built to handle the rigors of daily use and the challenges of harsh weather conditions, providing long-lasting functionality.

Off-Road Performance: For off-road vehicles, power running boards can be an asset as they keep the vehicle’s underbody free from debris while also offering easy access when needed.

Common Issues with Power Running Board Motors Like any automotive component, power running board motors can experience issues over time. Common problems include:

Motor Failure: Over time, the motor may burn out due to wear and tear, especially if the running boards are deployed and retracted frequently.

Electrical Issues: Wiring or electrical connections can deteriorate, leading to intermittent or complete failure of the running boards. This could result from corrosion, poor connections, or blown fuses.

Sensor Malfunctions: If the sensors that detect door opening and closing fail, the running boards might not deploy or retract correctly.

Mechanical Issues: The linkages and hinges can become clogged with dirt, rust, or debris, preventing smooth movement of the running boards. Regular cleaning and lubrication are essential to prevent this.

Improper Deployment: If the control module fails, the motor might not engage properly, causing the running boards to either not deploy or retract at all.

Maintaining a Power Running Board Motor Regular maintenance is key to ensuring the longevity and proper function of power running boards. Here are a few tips for maintenance:

Regular Inspection: Periodically inspect the motor and components for any signs of wear, rust, or dirt accumulation. Look for any loose wiring or connections that could affect performance.

Lubrication: Ensure that the linkages and hinges are properly lubricated to allow smooth movement of the running boards.

Clean the Mechanism: Keep the moving parts clean and free of dirt and debris. A buildup of grime can hinder the operation of the system and cause mechanical failure.

Test the System: Regularly test the system by opening and closing the doors, ensuring the running boards deploy and retract smoothly. If you notice any irregularities, have them checked immediately.

Check the Sensors: Verify that the sensors are functioning correctly, as they play a crucial role in ensuring the running boards deploy and retract at the right times.

Replacing a Power Running Board Motor If the power running board motor fails, it is possible to replace it. Depending on the vehicle, this can be a moderately complex process that requires mechanical and electrical knowledge. It typically involves removing the damaged motor, installing a new one, and ensuring the system is properly calibrated and functional.

For DIY enthusiasts, replacement motors are available from various manufacturers, and they can often be sourced from the vehicle’s original manufacturer or through aftermarket suppliers. However, if you're unfamiliar with the system or the vehicle's electrical setup, it's advised to seek professional assistance to avoid causing further issues.

Conclusion Power running board motors provide a valuable solution for easier vehicle entry, especially for taller trucks and SUVs. While the systems are convenient, regular maintenance and occasional repairs are essential to ensuring their longevity and functionality.
