FOG LAMP ALIGNMENT

To adjust fog lamp alignment, rotate the alignment

screw located at the top edge of the fog lamp until
desired position on alignment screen is reached.

FOG LAMP ALIGNMENT - CANADA/EXPORT/RHD

To adjust fog lamp alignment, rotate the alignment

screw located on the bottom of the fog lamp from
under the fascia to achieve the specified pattern posi-
tion. (Fig. 9).

HEADLAMPS

DIAGNOSIS AND TESTING - HEADLAMPS

Always begin any diagnosis by testing all of the

fuses and circuit breakers in the system. Refer to the
appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector repair procedures, details of wire harness
routing and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds.

Conventional and halogen headlamps are inter-

changeable. It is recommended that they not be
intermixed on a given vehicle.

HEADLAMP LEVELING MOTOR

DESCRIPTION

Two leveling motors are used per vehicle, one for

each headlamp. These leveling motors are attached
to the rear of the headlamp. They can be described
as a small semi-square shaped module with an elec-
trical connector attached to one side. Due to vehicle
design these motors can only be serviced or accessed
from the under side of the vehicle.

OPERATION

The headlamp leveling motors move the headlamp

and beam pattern according to the signal received
from the headlamp leveling switch. With the vehicles
headlamps “ON,“ a signal voltage is sent from the
headlamp leveling switch and received at each of the
headlamp leveling motors. This signal voltage (typi-
cally 2 - 9 volts) tells the headlamp leveling motors
were to position the headlamps.

HEADLAMP LEVELING MOTOR DIAGNOSIS

CONDITION

POSSIBLE CAUSES

CORRECTION

ONE MOTOR DOES NOT
OPERATE.

motor.

2. No voltage at motor.

2. Repair no voltage condition. Refer to Wiring
Diagrams.

3. No ground at motor.

3. Repair no ground condition. Refer to Wiring
Diagrams.

4. Defective motor.

4. Replace leveling motor.

BOTH MOTORS DO NOT
OPERATE.

1. No voltage at or from headlamp
leveling switch.

1. Repair no voltage condition. Check for
proper headlamp leveling switch operation.

2. No voltage at leveling motors.

2. Repair no voltage condition. Refer to Wiring
Diagrams.

3. No ground at leveling motors.

3. Repair no ground condition. Refer to Wiring
Diagrams.

4. Both motors defective.

4. Replace both motors.

REMOVAL

(1) Disconnect and isolate the battery negative

cable.

(2) Remove the appropriate headlamp unit (Refer

to 8 - ELECTRICAL/LAMPS/LIGHTING - EXTERI-
OR/HEADLAMP UNIT - REMOVAL).

(3) Disconnect the headlamp leveling motor electri-

cal connector (Fig. 12). Depress the steel retaining
clip while pulling the connector from the motor.

(4) Rotate the headlamp leveling motor counter-

clockwise. Pull it slightly away from the headlamp
and rotate it down to remove the ball from the socket
(Fig. 12).

NOTE: Significant force will be required to unsnap
the ball and socket connection between the head-
lamp leveling motor and the headlamp unit.
