DESCRIPTION AND OPERATION
HEADLAMP LEVELING MOTOR
DESCRIPTION
Vehicles equipped with a remote headlamp leveling
system use two leveling motors attached to each
headlamp mounting bracket. They are located just
behind the headlamp assemblies and must be
accessed from underneath the vehicle.
OPERATION
This system allows the driver to adjust the vertical
headlamp aim from the interior of the vehicle to com-
pensate for passenger or cargo load. A headlamp lev-
eling switch is located in the instrument panel and
controls the headlamp leveling motor function.
DIAGNOSIS AND TESTING
DIAGNOSTIC PROCEDURES
When a vehicle experiences problems with the
headlamp system, verify the condition of the battery
connections, fuses, charging system, headlamp bulbs,
wire connectors, relay, high beam switch, dimmer
switch, and headlamp switch. Refer to Group 8W,
Wiring Diagrams for component locations and circuit
information.
