Horn does sometimes works, sometimes not

[rasmeidirt]

i do not have fuse box photos both, cab nor fender top
id have to look.

Thanks. What I did was to remove the two horns to test with 12v battery, all work!!
Then, going look for fuse.

The horns sometimes work sometimes not! I want to say sometimes I hear the horn and sometimes I hear only the CLICK when press any switch at the steering.
