deck/lights not turing on help~!

What year 'stang is it? I'm gonna take a stab in the dark and gues that it is an older fox body with the aimable map light. I would pull the light down and check the connections behind it. The switches in those lights are notoriously crap, wiggle it and see if the light comes on. As for the rest of the problems, all of them going out at once makes me think fuse. Use a test light or meter and test the fuse, I've seen some that look good, but are in fact bad.

Sounds to me like by you moving the light around, being that it is old and didn't work before caused a short in the curcuit and blew a fuse. All the lights that you are having problems with are on the same curcuit so a bad fuse would really be just about the only option, unless all te lights are wired in series, going through the map light first. If by moving it around you broke one of the wires it could cause the rest to quit without blowing a fuse, but it is very unlikely. Get a 12 volt test light and check the wires and all the fuses. I think there is a fuse box under the hood which is probably where the fuse is for the light.
