Triz,
This isn't going to be a fuse issue if the tails and dash lites are working.
The corner lites up front are the first thing to see power out of the tailight relay and then the power goes out to the other lites on the circuit. If the tails and other lites are working, the fuse and tailight relay are operating correctly.
The corner lites are fed power on the green/white wire coming off the bottom of the tailight relay socket in that front box. There is a splice that feeds them hidden in the wire harness in the vicinity of that front fuse box.
Step one is to check for power on that green/white wire at the light sockets with a testlight or voltmeter. Make sure there isn;t corrosion in the terminals or bent pins preventing the bulbs from recieiving power.
Step two is check for ground at the sockets on the black wire with an ohmeter. Each side uses a different location for grounding, so it's unlikely your problem will be there ...
If you don't have power at the sockets, you'll have to start working back upstream. I have seen several cars have problems with the harness directly under the front fuse box. The wires can chafe against the sheetmetal under the box and break.
... but I'd start with the simple sh*t first.
Make sure you have good bulbs, (test them in another location on the car)
Make sure you don't have corrosion in the bulb sockets.
Make sure the wires are intact at the back of the socket, and there is no corrosion on the pins.
Check to make sure the grounds are clean and bolted to the inner fenders. They are about ten inches back on each side, and have a single screw holding them to the sheetmetal. There are multiple wires on each screw, so just make sure there's no broken wires or other obvious isssues, and that everything is clean, tight, and there is no corrosion under the screw preventing it from giving a good ground.
Good luck, and if you get stuck, pm me your phone number and I'll walk you thru some troubleshooting steps over the phone.
John
