what is the fuse number for the automatic ambient light control switch on a 2007 grand marquis
Picture of fuses for lighting control module, if you think the problem is a fuse. Not only check the fuse, use a test light and check voltage on fuse circuit. As you can see some fuses are hot all the time, some go hot with the key on. I don't much like auto headlamps. Just my opinion. As long as they will work manually, I'm ok.
