GENERAL
INFORMATION
Electrically-operated remote control mirrors are
available as an option on D-body vehicles. The mir­
rors are controlled by a single switch assembly lo­
cated on the instrument panel to the right of the
headlamp switch (Fig. 1). D-body vehicles use a toggle-type switch. The
switch is rotated clockwise (Right mirror) or counter­
clockwise (Left mirror) for mirror selection. The
switch is moved UP, DOWN, RIGHT, or LEFT for
mirror movement direction. The motors which operate the mirrors are part of
the mirror assembly and cannot be serviced sepa­
rately.

OPERATION

GENERAL
INFORMATION
The buzzer module is located to the right of the
steering column (Fig. 1). The buzzer sounds an audi­
ble warning tone in any of the following conditions: • Vehicle lights are ON when the driver's door is
opened.
• The key is in the ignition and the driver's door is
open. • The ignition is switched ON and the driver's seat
belt is not buckled. Buzzer will quit after 4 to 8 sec­
onds.
In addition to the buzzer, a seat belt light in­
dicator turns on as a reminder to fasten seat belt.

MODULE

WIPE MODULE

Fig, 1 Buzzer Module Location

OPERATION
Battery voltage for module operation is supplied to
two pins. Battery voltage is present at pin 7 at all
times (Figs. 2 and 3). Pin 1 receives voltage when
the ignition switch is turned ON.
SEA T BELT WARNING To sound the seat belt warning, the module needs:
• battery voltage at the ignition switch input (Pin 1)
• a ground at the seat belt switch.
• a ground at Pin 3 to activate the timer. This occurs when the seat belt switch is closed be­
cause the driver's seat belt is not buckled. The "fas­
ten belt" light will also turn on along with the
warning sound. KEY IN IGNITION
To sound the "key in ignition" alarm, the module

needs:

• the ignition key warning switch must be closed
• the driver's door jamb switch must be closed. These conditions ground pin 6 of the module. These
switches are closed when the driver's door is open
and the key is in the ignition.
LIGHTS ON To sound the "lights on" warning, the module

needs:

• the headlamp switch must be closed
*> the driver's door jamb switch must be closed. These conditions ground pin 6 of the module. These
switches are closed when the driver's door is open
and the headlamp switch is on.

DIAGNOSIS
If the buzzer unit does not operate as described,
check the two fuses for pins 1 and 7 (Figs. 2, 3 and 4) and replace as required. If the fuses are not defec­

tive,
perform the following tests to determine if the
problem is in the module or in the wiring. Using a flat blade screwdriver, release the locking plastic clip
while carefully pulling out the module. Plug in a known good module and check its operation. If the
problem is not corrected by replacing the module, re­ move the module and continue as follows:
VOLTAGE TESTS Ignition in run, measure between the following
pins and vehicle ground.
• Measure voltage at buzzer module connector pin 1.
Meter should read battery voltage. If not, repair open
to ignition switch.
Turn ignition off and remove key from igni­

tion.

• Measure voltage at buzzer module connector pin 7.
Meter should read battery voltage. If not, repair open
to fuse. Battery voltage is present at Pin 7 at all
times regardless of key position.
