I have a 2003 Grand Marquis with automatic lights that shut off at random times. Sometimes they are on then they just shut off by themselves. Sometimes they come back on if I hit a bump sometimes they do not.
- Wiring or connector fault.
- Defective LCM (Lighting Control Module).
- Defective headlight switch assembly.
- Defective light sensor assembly.
- Defective circuit breaker.
