Hmm ligh dont light

[phatdaddy]

can u check voltage at the lamp base with the bulb in the socket
check voltage leaving the switch
check continuity from the switch to the fixture on each leg
i have found a 12 volt test light is better than a meter because it puts a load on the voltage
just guessing, but it sounds like a bad ground

Maybe a wire came loose at the back of the switch. There are quite a few wires that go to that switch.
