Hello all! 85 gt. I think the front drivers side park circuit is shorted to the same turn signal circuit?....and here's why..... When lights (either park or full on) are on, the left dash indicator illuminates but neither do the outside front drivers side front and side lamps. When the same side turn signal is switched, the inside indicater gets brighter, but stays constant on, the rear lights up, but still no FRONT. The right seems to be unaffected. Where do I look first?

Wild guess,but you might allso want to check your bulbs.Make sure you have the correct bulb installed (single or duel filament). In a duel fillament bulb when one of the filament breaks it can arc to the other filament causeing bridge, be sure to check the bulb filaments too.
Thanks all for the replies. I've replaced the bulbs and inspected the sockets for shorts and bent tabs.. According to the link ogre supplied and northstar's suggestion, bad grounding would be the first place to look.
Where is the ground point for this circuit? Ron

It could possibly be a relay mounted on the front wall of the spare tire tub, on the driver's side.
Sorry, I meant the wall forward of the driver's side headlight. On one of my cars, the left turn signal was on all of the time, and it turned out to be because this relay was loose in it's socket.
See my Cave, Wire Service Bad/loose Ground points on frame won't help but problem there will cause more issues then 1 park/turn bulb flipping out.
Socket can be bad and still look ok to you. To get more room, lift HL and pull out park socket from back. (Easier that way too just to change that bulb.)

Maybe. That is Radiator fan relay and uses 1 of 2 wires at G101. Sounds like G101 is/was loose and loose relay didn't help.
I would (and did on my car) clean both front ground, clean frame to bare metal, and lube well w/ silicone. (In my case, I redrill an iffy hole for G102 then lube both to stop rust.)

.....wealth of knowledge! Great write up on the grounds and wiring! Looks like I'll be busy checking ground points today! (yippee)
UPDATE: Got it sorted last night. It was the front directional ground lead inside the socket. i slid it back and forth a few times and VOILA!....the lights came back on and all the weird stuff stopped .
