For fuse circuits like this, that serve more than one device, it can be useful to 
pull the fuse "box" down so you can get at the wires that feed each device. 
Remove all but one of the wires from the output side of that fuse, then check 
to see if that fuse still blows.

If that fuse no longer blows, check to see which device now works. Now you 
know which device is not a suspect in your search for a short.

If that fuse still blows, remove that wire, connect a different one., and start 
over.

Eventually you will narrow down the suspects to just one that has the short. 
The last time I had to do this, the problem was a bulb where someone had 
forced an incorrect bulb into the socket. Note that our cars have some bulbs 
with single contacts on the bottom and some with double contacts. They are 
not interchangable.
