1994 Ford F-150

Electrical problem
1994 Ford F150 V8 Two Wheel Drive Automatic

i recently bought this '94 F-150 supercab (used obviously) and the previous owner had damaged the front passenger headlight. I bought a new bulb to check if the bulb just needed replaced or if the entire socket needed replaced. Moisture got onto the bulb and it blew, causing other problems. Now I have no tail lights or interior lights (dash, etc.). I have checked the fuse under the dash (fine there) and I replaced the switch in the dash because one of the plugs on the switch had obviously shorted because it was melted (fine there as well now). After replacing the switch though, no improvement. I'm at a loss. What do you suggest I look for and where should I look?
