Instead, the control of the various lights is handled by:
* Body Control Module (BCM): This is the most likely candidate for the "brains" of the lighting system. The BCM receives inputs from various switches (headlights, taillights, etc.) and sends signals to the appropriate relays and actuators to control the lights. The BCM is usually located under the dashboard, often near the steering column or under the carpet on the driver's side. Its exact location varies slightly depending on options and trim level. You'll likely need a wiring diagram or a repair manual to pinpoint it precisely.
* Various Relays and Actuators: These are controlled by the BCM. They actually switch the power to the different lights. These will be spread out throughout the car near the related components (headlight relay near headlights, etc.).
* Individual Light Switches: These directly control some aspects of the lights (like interior lights).
To diagnose lighting problems, you should consult a repair manual for your specific 1996 Lincoln Town Car. A wiring diagram will show how the different components are connected and will be essential for troubleshooting. Without one, tracing the issue accurately is difficult and potentially damaging.
