Lights on my 2004 Crown Vic will not work in automatic light setting. Have tried 2 different LCM plus new switch plus new sun sensor. Any thoughts?

At some point each one of these LCM have flashed the lights on and off during daylight hours

SOURCE: headlights going on and off

Unfortunately it is the light control module. This is a very common problem on the Crown Vic's, especially the 2003-2006 models. Try your local junk yard. It is located under the dash just above the gas pedal. There are 4 small screws that hold it in and one small wiring harness.

SOURCE: Rear and interior dashboard lights don't work 1994 Crown Vic.

Easy stuff first. Try replacing the #9 fuse on the interior fuse panel. This fuse protects the instrument panel, license, parking and tail light circuits. The panel is located under the dash to the left of the steering column. You will need to pry off the cover on the panel to access the fuses. The fuse you want is a 15 amp fuse located directly under the turn signal flasher. It should be easy to figure out which fuse it is because it will be 'blown' or open. This is easy to determine just by looking at the fuse once it's removed. And, if you aren't sure what's what, I'm sure you can find a diagram of this fuse panel somewhere on the Internets if you look around a little. I took this info out of the Owner Manual from my own '94 Vic. If this doesn't solve the problem I would suggest taking your Vic to a shop and letting them take a look at it.

The head light controls on a police car are exactly like those on any other Crown Vic. I have repaired dozens of them. More than likely you have no contact inside the multifunction switch. I would replace the switch as the most likely source of the problem. These are easy to change, just remove both halves of the plastic cover around the steering column and there are two Torx (also called star screws) screws holding the switch onto the column. The screws are on the bottom down in wells of the lower calm shell cover, they are cross points (Phillips)
This is a fairly common failure on police cars (P71 and P73 option).

There is a resistor in the light control module under the driver side of the dash. You can replace the whole module which is about 100+ dollars or if you're good with soldering, replace the resistor. You will need to remove the box and open it up. Find out the resistor part number and replace it. This is a common problem on the 03-05 crown vics. Good luck

Insrument panel loses power periodically

this is just a loose fuse or connector wiggle the connector of the lighting control module just above you gas pedal under the dash.turn lights on try to kick slightly the module(black metal box).Sometimes you need to open it and re apply heat and solder on the relay terminals fixed on the board.
