Insrument panel loses power periodically

I am also having the same problem with my 2006 Crown Vic.
I've taken the LCM out and put it back in. Still no luck.. Replaced the battery, headlight switch, and ignition switch. replacing the LCM is about $500, any other sugestions to check??

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.
