I have an 88 Honda that has the horn fuse under the hood along with some of the relays. A black box above the car battery. I know the question is about a 92 Honda but you might want to check that box if you haven't already. I was breaking my head with the same question for a while until I checked under the hood.
A short circuit somewhere.
The 1997 Honda Civic Horn relay is found under the drive side dash panel. The relay is mounted next to the starter relay on the right side of the fuse box.

The 1992-1995 Honda Civic LX Sedan has a 102 horsepower 16 valve engine called the D1587.
The exact oil capacity for a 1992-1995 Honda Civic DX/LX is 3.7 quarts.
While this is for a 1992 Honda Civic, I've been told it is the same for a 1991 model. http://autoforums.carjunky.com/Automotive_Repair_C1/Electrical_and_Wiring_F6/FUSE_BOX_DIAGRAM_FOR_92_HONDA_CIVIC_P3020/
