the headlight control module is going bad, it is located under the dash up where the right knee is, it is a box avout 6 inches long and 4 inches wide.
most likely bad switch
Bad switch? Headlight Relay Fuse/Breaker needs replacement
the 4way mutil.switch. Headlights. turn sig. wiper washer. I was not the lcm.
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
On a 1998 Ford Crown Victoria : If you mean that you want to turn on the high beam headlights ( push the turn signal lever forward , away from you )
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.
It usually means that there is either a short in the circuit or the breaker is faulty.
Remove that wide black plastic piece above the headlights. Then using a 4 mm socket you have to turn the screws with black plastic around them.
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
