BSNOVT PowerStep Side Step Motor Replacement 80-03129-90 — Three-Bolt Direct-Fit with Gaskets & Screws

BSNOVT 80-03129-90 is a direct-replacement electric side step motor built to restore automatic retract-and-extend function to AMP Research PowerStep running boards using a three-bolt mount.

If your vehicle’s PowerStep running board has stopped deploying or retracting, this replacement motor from BSNOVT provides a cost-effective, OEM-style fix. Engineered to match the three-bolt mounting pattern of AMP Research motors, this unit replaces part numbers 80-03129-90, A10049-113, and 800312990 and fits on either side of the vehicle. The kit arrives with the motor, three metallic gaskets, and three mounting screws for a straightforward swap-out of the original component.

How will this motor restore my running board’s operation?

The BSNOVT motor re-establishes the electromechanical action that moves the PowerStep running board when doors open and close. It replicates the original mounting and electrical connection so the step can automatically extend and retract as designed.

• Replaces worn or failed AMP Research three-bolt motors
• Works with existing wiring and plug; no special adapters required
• Restores automatic door-triggered deployment and retraction
• Includes gaskets and screws for secure mounting

Is this part compatible with my vehicle and how do I confirm fit?

Compatibility depends on the original AMP Research replacement part number and the three-bolt motor interface. Verify your current motor’s part number before buying to ensure a match. The BSNOVT unit is designed to fit both left and right sides without side-specific orientation.

• Intended as replacement for 80-03129-90, A10049-113, 800312990
• Three-bolt mounting pattern mirrors AMP Research originals
• Can be installed on left or right side interchangeably

What does installation involve and what’s included in the package?

Installation is a direct swap: remove the original motor’s three mounting screws and unplug the single wiring connector, replace with the BSNOVT motor, refit the screws and reconnect the plug. No special tools or modifications are typically required.

• Package contains 1 motor, 3 metallic gaskets, and 3 mounting screws
• Unplug original connector, remove three screws, swap parts
• Torque screws to vehicle manufacturer specs for secure fit
• Minor electrical inspection recommended after installation

What performance and durability can I expect from this replacement motor?
