Electrical Short for Interior Lights in 99 Accord
 

Hi all -

I have a '99 Accord LX 4-door that appears to have a short in the interior
lighting. It appears the only things on this circuit are the map lights in
the front headliner, the overhead light, the lights in the bottom corners of
the doors, and the door switches. The cigarette lighter (unused) is on a
different circuit.

The circuit runs on a 7.5 amp fuse - if I replace the fuse even with the car
turned off I get an *immediate* spark and a blown fuse. I tried with a
20amp fuse as well, just to see if the circuit was overloaded for some
reason, and I get the same result - immediate spark and a blown fuse.
Obviously a short.

The question is - does anyone have any ideas where the problem may lie, or
perhaps some steps to begin troubleshooting the problem?

Thanks for any help you can provide!
