You'll likely find the relevant components in these areas:
* Body Control Module (BCM): This is the most likely candidate for the brains of many lighting functions. It's a central computer that handles many aspects of the car's electrical system, including things like auto-lamps, interior lights, and potentially some exterior light control. Finding the BCM in a 1995 Town Car will require consulting a wiring diagram or repair manual specific to that year and model. It's usually under the dash or in the area of the fuse box, but the exact location varies.
* Turn signal switch stalk: This contains the switches for the turn signals, hazard lights, and possibly headlight high beams. Problems here can affect lighting function.
* Headlight switch: This controls the low beams and might incorporate other functions. Issues within the switch itself can interrupt proper operation.
* Individual light switches and relays: Some lights, particularly interior lights, may have their own switches and relays.
To diagnose a lighting problem, you'll need to identify *which* light(s) aren't working correctly. This will help determine where to focus your search. A wiring diagram or a repair manual is essential for tracing the circuits and identifying the relevant components. You can find these online or at auto parts stores.
