'90-96 Chime Module
IF THE IMAGE IS TOO SMALL, click it.

Note that '92-93 Broncos' & F-series' left front courtesy switch is a rare plastic design (Standard DS838) located at the bottom of the B-pillar (instead of the metal design in the lower A-pillar for all other years '80-96/7). From '94-96/7, the driver's switch (Motorcraft SW6345) returned to the lower A-pillar, like the passenger switch always was.

The warning chime/buzzer module produces a repetitive chime or steady buzzing sound for the following conditions:
- Fasten safety belt warning.
- Key-in-ignition warning with driver's door open.
- Headlamps-on warning (available on some models).

The warning chime/buzzer sounds when the driver's door is open with the key in the ignition switch (11572), and continues to sound until the key is removed or the door is closed. When the key is in the ignition, the key-in-ignition switch is closed and ground is supplied to the warning chime/buzzer module through Circuit 158 (BK/PK). When the driver's door is open, the driver's door courtesy lamp switch (13713) is closed and power is supplied to the module through Circuit 159 (R/PK).

When the ignition switch is turned to RUN or START, power is supplied through Circuit 640 (R/Y) to the warning chime/buzzer module, which then supplies power through Circuit 450 (DG/LG) to illuminate the fasten belts indicator for six seconds, whether or not the driver's safety belt is fastened.

The safety belt warning will sound for approximately six seconds unless the driver's belt switch is open (buckled or unplugged).

The warning chime sounds when the headlamp switch (11654) is in PARK or HEAD and the driver's door is open, and continues to sound until the headlamp switch is moved to OFF or the door is closed. When the headlamp switch is in PARK or HEAD, power is supplied through Circuit 14 (BR) to the module. When the driver's door is open, the driver's door courtesy lamp switch is closed and power is supplied to the module through Circuit 159 (R/PK).
