Accent 1999 lights problem

Hi,
I have a serious problem with the lights on my Hyundai Accent 1999.
The following things don't work: instruments light, front fog lights, front left
positioning light, back left positioning light, left back break light.
I tried all the circuit breakers, and wire contact and nothing
The mechanics want to tear the whole car apart which is really the last resort.
I manager to get the 2006 Hyundai manual CD but the circuits are different than
on my '99 model.

please help, any advice is highly appreciated

You can view the schematics for the American version of your car at
www.hmaservice.com. You'll need to register for a free account, and the
site requires Internet Explorer. You may also need Adobe SVG Viewer to
see the schematics. Once you've logged in, enter your year and model and
go to the ETM (electrical troubleshooting manual) section and select the
appropriate schematics. Most non-DRL lighting circuits should be the same
or similar to U.S. models.

The left positioning lamps and instrument lamps all receive their power
from the Left Tail fuse in the underhood fuse box. Start there for with
your diagnosis on these lamps.

The fog lamps and brake lamp are each on separate circuits. Start with
checking these bulbs if you haven't yet done so.
