Where is exact location of horn fuse. I know there is a 15 amp Horn Relay fuse in the engine compartment and that works. Where is the other horn fuse... engine compartment or inside under steering whee? Where and what is fuse location slot number?

 

Do you want the horn relay or the fuse?
Engine compartment has set of relays and fuses (Power Module)
The cover should have a legend to be able to identify the items in the power module

Check your owner's manual for more information on where the fuses are in the cabin
