See: http://www.p71interceptor.com/lcm/ fo info.. The earlier models used a circuit breaker in the fuse block that can go bad and cause the lights to flash or it can be the "lighting control module" that is At Fault..
i have a 99 and it does it too...
Headlights have a thermal circuit breaker. A short to the headlight (positive to ground) will cause the breaker to trip. The breaker cools and the lights come back on till the breaker heats up. Find the short and fix it.
I would replace the headlight switch as Ford has had their share of these problems.
Had the same problem. Exchange the LCM (Lighting Control Module), which is located under the steering column, togehter with the Mulitifunction Switch (turning lights, wiper control lever). This will stop the headlight problem, but I have some other difficulties with my lights - have a look at: http://www.2carpros.com/forum/2003-crown-vic-police,-headlights-shut-off-while-in-opera-vt90501.html
most likely bad switch
You don't say what year of Ford Crown Victoria , but if you move the turn signal lever forward it will turn on the high beam headlights
sounds like a bad day and night sensor or bad wiring
You've got a bad headlight switch and need to replace it, that's the switch you pull in the dash to turn the lights on. That's why the headlights only work on bright but not dim.
If you mean how do you activate the high-beam headlights, pull the turn signal lever back towards you until you hear a click.
Possible headlight switch.
crown Victoria blower not working and head lights.
probably because you bought a car designed by baboons.
