What this part does

The Sunroof Motor is a high-torque electric actuator responsible for operating the glass panels in the roof assembly. It sits concealed above the interior headliner, directly bolted to the sunroof track frame. The motor features an internal gear that engages with the mechanical drive cables to tilt, slide, open, and close the glass. When the motor fails or its internal gearing strips, the sunroof will typically become stuck in its current position, fail to respond to switch commands, or produce an audible clicking and grinding noise without moving the glass.

Before you order

Before installing a replacement Sunroof Motor, thoroughly inspect the roof cassette tracks and cables. Mechanical binding, dried grease, or debris in the tracks is the primary reason these motors burn out; if the tracks are not cleaned and lubricated, the replacement motor may suffer the same fate. Once installed, the new motor requires an initialization and calibration procedure to learn the end stops and anti-trap pinch protection limits. This can usually be done by pressing and holding the sunroof switch for a specified duration, or by using an advanced diagnostic scan tool.
