Are you not getting power through a connection? Did you check to see if there is power at the horn when it is pressed?

MAY BE A COMPONENT ALONG THE WAY, FUSE, RELAY, ETC
GOT ANOTHER EXPERT LOOKING FOR YOU A DIAGRAM OF THE SYSTEM AS I TYPE
YOUR HORN PROBABLY LACKS A COMMANDING VOICE, EVEN WHEN IT DOES WORK
MINE "TAKES CHARGE" IN ALMOST EVERY SITUATION. EVEN FREIGHT TRAINS STOP, WHEN I CROSS IN FRONT OF THEM!
MIGHT WANNA LOOK INTO IT!
DIAGRAM SHOULD ARRIVE BELOW ME SOON

I have looked for a wiring schematic for this vehicle, but can't find one. The only things listed for an Isuzu truck are the following: Hombre, Oasis, Rodeo, Trooper. Is there a specific name for this vehicle other than NPR 250?
