What this part does

The tailgate motor, commonly referred to as a spindle drive, electronically controls the automated opening and closing of the rear trunk lid. Mounted alongside the trunk hinges, it relies on an internal threaded spindle and electric motor to extend or retract smoothly when prompted by the trunk control module. If this component fails, the trunk lid may struggle to open, close only partially, drop unexpectedly, or produce noticeable grinding and clicking noises during operation.

OEM and interchange numbers

UA735709707

Before you order

• Verify the OEM number against your original unit, as left and right spindle drives are often side-specific and cannot be interchanged.
• After installation, the power tailgate system usually requires initialization using a diagnostic scan tool to learn the upper and lower end stops.
• Inspect the wiring harness connector at the trunk hinge for any signs of pinching or fraying, which can mimic a motor failure.
