Liftgate/Tailgate Actuator

What is an Actuator for a Liftgate or Tailgate?

A power liftgate or tailgate actuator is an electronic component that allows a liftgate, tailgate, or rear door of a vehicle to be opened and closed with the press of a button or using a switch. The actuator functions as a small electric motor that moves a linkage or latch to automatically release or move the liftgate or tailgate to allow it to open or close when prompted. Some actuators are also designed to pull the liftgate into the vehicle if it is closed manually to seal it against the weatherstrip. Over time, the tailgate or liftgate actuator may wear out or stop working, and this may point to issues such as motor failure, worn gears, electrical faults, or sensor malfunctions. If your vehicle's tailgate will not open or close automatically, this may indicate an issue with the power tailgate actuator, but you may also check the sensors, switches, relays, and other electrical system components related to the liftgate to ensure that the actuator is the source of the problem. Actuators often make noise when they begin to fail, and this may be a clear indication that your liftgate actuator is worn, damaged, or that internal components of the actuator have broken or fallen out of alignment. O'Reilly Auto Parts offers a selection of replacement tailgate and liftgate actuators, connectors, relays, switches, and other electronic components to help you keep your vehicle's systems operating as they should.
