The headlamp leveling motor is located on the rear inboard side of each headlamp unit on models equipped with the headlamp leveling system, which is available only in certain markets where required. See Fig 1. The motor is encased within a molded plastic housing and is secured by an integral wedge-type mounting boss to a keyed flange on the back of the headlamp unit housing. A rubber seal around the circumference of the mounting boss seals the motor to the headlamp.

The outside of the motor housing features an integral molded connector on its rearward surface, a hex-headed adjusting screw extends from the top of the housing, and a plastic pushrod with a ball formation on its free end extends from the motor mounting boss. Within the motor housing is a 12-volt Direct Current (DC) servo motor, an electronic controller board that includes the motor logic circuits, and an integral screw-drive transmission. The headlamp leveling motor is connected to the vehicle electrical system through a dedicated take out and connector of the front fascia wire harness.

The headlamp leveling motor cannot be repaired and, if faulty or damaged, the unit must be replaced.
