l cant seem to find which fuse l need to change for the horn on my 1993 Honda Civic DX.l put in an aftermarket steering wheel and did not bother to hook up the horn because l never use it, but l wanna hook it up again and it did not work.My friend said the fuse might have blown when l changed it, but l cant seem to find the horn fuse on any diagrams.Please help, I am quite a car guy but I am a little confused right now.thanx

the fuse is in the underhood fuse & relay box. look under the cover. it is the 20 amp fuse for the horn & stop lamps. easist ''test'' is to have someone step on ur brake pedal & see if u have stop lights. if u do then the fuse is good.

if the car has supplemental restraint system (air bags) then u also have a horn relay in the underhood relay box. that could be the reason ur horn does not work. if there is no airbags on the car then u do not have a horn relay (not sure if teh DX had airbags or not)

have u tried the horn itself? If u put 12 volts & a ground to the horn it should work. In most cases the horn is dead.

hope that helps
