Park/tailight fuse (10 amp) under hood suddenly blows; also a 15 & 20. All other functions/lights OK; just park/tailight circuit. Isolated rear lights by disconnecting harness behind drivers kick panel; still dead short w/ light switch on positiion 1 (park/tailights). Unplugged light switch; no more short. By the way, I'm checking for short by probing the dead side of the park light fuse w/ live circuit tester. I'm guessing short is in the front harness somewhere (to the front lights) or possibly the light switch itself. Can't see a problem on the harness anywhere. Removing all the bulbs changes nothing; all sockets appear normal. Nor can I find any means of isolating this harness alone (integral w/ the harness into the switch). Any tips/ideas? I can't find a good schematic anywhere. Anyone kind enough to send one to djjsc(at)juno(dot)com??? Thanks for the help! Doug
