GENERAL INFORMATION
For proper operation of the Concealed Headlamp
System, refer to the Owner’s Manual provided with
the vehicle.
The Concealed Headlamps are controlled by the Body
Controller (Fig. 1). Refer to Group 8E, Instrument
Panel for service procedures. The Body Controller re-
ceives input information from the ignition switch, head-
lamp switch, and the headlamp dimmer switch.
The Body Controller also controls the headlamp doors
when the Passing Lights (manually flashing bright
lights) are used. With the headlamp switch turned off,
actuating the headlamp dimmer switch will signal the
Body Controller to open the headlamp doors. The oper-
ator then has two seconds to flash the bright lights be-
fore the Body Controller closes the headlamp doors.
Holding the headlamp dimmer switch in the engaged
position will signal the Body Controller to keep the
headlamp doors open until the dimmer switch is re-
leased. Actuating the headlamp dimmer switch with the
parking lamps ON signals the Body Controller to open
the headlamp doors and keep them open until the head-
lamp switch is turned off.
AY and AC vehicles use a single motor, centrally
located behind the radiator grille, and linked to the
headlamp doors by a torsion bar. Refer to Service
Procedures for more information.
The headlamp door drive motors are equipped with
a manual override hand wheel to open or close the
headlamp doors if a failure should occur or servicing
is required. Access to the handwheel can be gained
through a flap covered hole in the sight shield be-
hind the bumper fascia, and under the hood. Several
revolutions of the handwheel may be required to
move the headlamp doors.
DIAGNOSTIC PROCEDURES
Before diagnosing a problem with the headlamp
doors, check for possible collision damage, binding,
improperly installed assemblies, or freezing weather
conditions.
When diagnosing an electrical problem, refer to:
• The Concealed Headlamps Electrical Diagnosis
chart in this section.
• The Wiring Diagrams Manual.
• The Headlamp Doors System section of the appro-
priate Body Diagnostic Procedures Manual.
PROBLEM
One headlamp door is inoperative when the head-
lamp switch is ON and the ignition switch is in the
RUN position. The other headlamp door operates
normally.
AC OR AY-VEHICLE BODY CHECK:
• Headlamp door pivot and crank for seizure.
• Headlamp torsion bar sleeve or clip for excessive
wear or breakage.
• Headlamp door crank for missing or broken screw.
• Headlamp torsion bar for disengagement or break-
age.
PROBLEM
Headlamp door operates erratically.
CHECK:
• For freezing weather conditions.
• For excessive effort to move headlamp door pivots.
• For corrosion or improperly aligned components.
• For stripped motor reduction gears.
• For defective body controller. Refer to the Con-
cealed Headlamp Electrical Diagnosis chart in this
section. Also refer to the Wiring Diagrams Manual
and Body Diagnostic Procedures Manual.
