Good To Know

Q: Will this electric side power step running board motor operate both the driver and passenger side steps on GM and Dodge applications? A: Each side typically uses its own dedicated motor assembly, so a binding or stalled step on one side requires replacing the motor on that specific side to restore balanced operation.

Q: How can I confirm if the 80-03129-90 or A10049-113 cross-reference matches my vehicle before ordering this motor? A: Check the part number stamped on your original motor housing or refer to your vehicle build sheet, as trim level and option packages can affect which running board motor is used from the factory.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
