there's a short in the ciruit somewhere. Look to see if a wire is touching the chasie somewhere grounding it out..
hi your horn is defective ! there could be a short but it is widely known that a horn could still honk before blowing fuse,
the horn should be hooked up to a relay, horns generaly require to much current for a fuse
You have a short to ground, or an over current situation in the wiring.
The horn fuse is located in the fuse box under the hood on the drivers side of the truck. Lift off the cover of the fuse box and the underside of the cover has a labeled diagrahm. Find the 15 amp fuse. Remove and replace. However, I also have a 2003 suburban and found that the problem originates with a short in the horn assembly in the steerng wheel. The horn will keep working as a lock/unlock indicator, but will only work one time if the horn is activated on the steering wheel. It will keep blowing fuses.
The horn and parking lights may be on the same fuse, you need to look for a frayed wire or connector leading to your horn(s), it may be touching metal somewhere causing a short. The horn itself may also be the problem to check it disconnect the wire connector from the horn(s) and try it, if the fuse still blows keep looking for a wire touching metal.
A short circuit somewhere.
You don't keep Safari Balls. You only have them in the Safari Zone.
Check the horn - if it doesn't blow, then you may have found the culprit. In most cars, the lighter and horn are on the same circuit.
Under the hood in the fuse box next to the passenger hood hinge. It is #42 and labeled "Stop & Horn", NOT BRAKE! It is a 20 amp fuse. Before looking for this fuse, test your horn. If it beeps then the fuse is NOT blown! If the fuse is good and the brake lights still don't go on, test the brake light switch. If the switch is bad it will also keep you from going out of park and into gear!
A suggestion: First things first. Check owner's manual to see if there are other devices sharing the same fuse. If there is only the horn on that circuit, pull wire off the horn. Push horn button to see if the fuse still blows. If it doesn't then you know the horn element is shorted and the horn must be replaced. In my car, the horn shares a circuit with the cigarette lighter and interior lights. The cigarette lighter is a common cause of a short and thus will also short out the other devices. So, if it is a shared circuit, by process of elimination(disconnecting each device one-by-on) the short should be located and that device replaced.
Perhaps it's a shortage in the wireing? The horns may be located in the front bumper, right side, but i dunno where the wireing goes.
the horn fuse is on the right hand passenger side of the dash.
