The inside lights on my '03 F150 Lariat 4x4 don't work as they should. When you open the door, there is no light coming on in the front seats, overhead, or doors. The only inside lights that come on are in the back seat. Surely there are supposed to be more lights than that when you open the doors. Is this a fuse problem/ If so which fuses should I check? Can't seem to find the right ones according to the owners manual. Thanks.
