**** Using a Bentley, look at the schematic, see what is powered by that
fuse.
Almost all the doodad lights are powered by the 15 amp fuse, door swiches,
clock, radio, etc.
You dont have a Bentley? That complicates things a whole lot.

If it was me, I would hook up an ohmeter to the ciruit at the fuse. It will
read a short. Some meters will give you an audible sound, which is even
better.
Then, start operating those components that have flex wiring . .like the
doors, trunk , hood, glove compartment, etc.
When you hear an intermittant sound, or the sound goes away, you have found
a short to ground.

For a starter, I would check the light inside the glove compartment. Its a
flimsy plastic affair. If you have too much crap in the glove box, upon
closing the glove box door . . its possible to unlatch that lamp holder. The
holder will slide back and promptly ground the lamp leads . . and thats your
short. If you see that the lamp holder is loose and hanging, you have a
99.9% probability that you have found your problem.
