Blowing Parklight/ Dash light Fuse

ARGH!!! I went checked the bulbs and checked underdash for obvious signs the only thing I found was a park light bulb siezed into the socket removed and replaced with new one. Now the fuse is not blowing but I still have now parklights/dash lights, checked voltage at the fuse 0 V until I pull the switch then I am getting 12 V but no lights. Is this an open circuit???? Should I be looking for broken wires? Bad Grounds? I am lost and got less than a week before the Nationals. PLS HELP!!!
