Chances are this is a relay issue and wouldn't be uncommom. Replace the relay and let me know how it turned out.

Tengo una isuzu hombre 97 no m funciona el claxon cambie la bocina y no funcion? q hago?


english please.
is car the Brazil HOmbre? ours is different. here. in USA.

we are USA english forum
horn is dead, 1997 Hombre.
check the fuse yet,that is always first, marked HORN it is.
a 20amp fuse.

the horn is very simple. but the path it follows is complex
(due to steering wheel turns, complications in all cars made)
first off is air bags if car has air bags , working on horn parts in dash will be dangerous, so defeat air bags first. !
the FSM book tells how to do that. read that. and do that.
be safe.
so you can test the horn on a battery, hot wired. just like a light bulb. same test. but why would both horns fail>?"relay"
clean the horn base grounds so its not rusty.
sure one horn rust, ignored then 2nd rusts and owner acts.
you can check the horn relay, or replace it.
the check the horn relay coil for 12vdc across the coil of relay while honking, 12vdc honking, if 0v, that means the horn switch in the steering hub is bad or the airbag, clock spring contacts bad (danger area)
the horn button grounds a wire. to energize the horn relay.
it only takes a volt meter to test all this.
got one?
other wise it's a gue$$ing game.

our car (USA) is:
"In 1996, Isuzu replaced its Pick Up with a version of the Louisiana-built Chevrolet S-10, the Isuzu Hombre, based on the Brazilian market S-10"

so will answer for S10.
this car has 2 horns if both are dead, check the relay

using a volt meter,
i honk the horn and the bottom of the coil in relay below goes to 0v
from 12v.
if its not 12vdc to begin i check the top of coil there.
if that pin is 0v, the fuse is blown, good looking fuse can in fact be bad. we test fuses. not guess.
if you honk the relay closes, (can be seen or heard to close)
click?
if the relay does click, then he bottom contact below goes to 12vdc
if not the relay IS BAD.
the below horns grounds are missing , error in the manual.
the horn bases are grounded. to the car body. if not they will be dead.

Why won't my horn work on my 1991 jeep cherokee laredo?


the horn is simple , a horn a relay and switch, and fuse 15?.

but is complex by other factors.

1: the clock spring . no air bags in 1991, so very easy.



there are 2 ways to diagnose any horn..

1: hot wire it, does it now honk? if yes, hot wire the relay does it honk now?

2: or use any voltmeter ever made and find out why.



#2 is the save way.



id hot wire the horn and make sure that 1991 ground bolt

mount is really still at ground potential. id bet that bolt has

long sense rusted, and is useless, like most are by now.



the fuse and relay are both in the PDC

the PDC means, engine bay fuse box in gringo. (non jargon)

http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service

here is 93 for free.

see horn page one and the 2 tests.

or see the schematic.

at there, see the fuse box see fuse 15 (PDC 15?)

same chapter, see PDF page 90 (sheet33)



as you can see if the fuse is good.

12vdc arrives at the Horn relay on 2 pins.

if the horn switch works the relay ENERGIZES (closes)

and 12vdc arrives at the horn, and it honks

if while honking, the horn casing is 12vdc,

then means the horn is no longer grounded, a common happenstance.



if the relay dont energize check the horn ring contacts or connectors to it for continuity.

the relay can be tested, in the car.

like this.

honking

pin 2 and 5 are 12v

pin 1 = 0 volts

pin 4 is 12v, if 0v the relay is bad.



easy huh., ?

Horn doesn't work


i would check the ground out inside the steering wheel before anything else. these can get bent or broken off during a good panic honk or during a fit of roadrage. once ok'ed i would have a helper with a test light or volt meter check the system as you honk the horn to find out where the voltage stops. where the voltages stops will be the problem

Horn randomly honks(very annoying while your trying to sleep) HELP!


its possible that the relay is the problem as most relays have a second power feed wire,if it shorts to the horn side of the relay it can blow the horn.doesn`t happen very often but it does happen.this could explain the horn blowing without the fuse in.you can get a door key made at a lock smith to solve that problem.

Where can I find my honk sensor in a 2006 Ford Focus? or How to fix my honk in a 2006 Ford focus? The honk is not working?


I believe there are 2 wires to the horn. One is power all the time, and the other is ground through the steering column wire to the horn button on the steering wheel, when it grounds out when pushed.
If it is a single wire to the horn, then there is a relay.

The horn doesn't work.


Check for bad fuse in the panel. Check for a ground at the relay when you push the horn button. Gheck for power at the relay 12 volts or battery voltage. check the horn with a jumper wire from the positive post on the battery ,but unhook the wire on the horn first. Horn should honk! if horn is bad replace.

2000 Tahoe Horn broken


You can remove the horn relay and use a Ohm meter and check the resistance between the horn relay connector terminal No. 86 (Black Wire) and ground. If the ohms are less then 5 ohms replace the horn relay. There are a lot more tests but as Polarcycle states you can do what he suggested other then I believe you have two horns in this vehicle.

Hi,

As in most electrical problems, it would be required to do a bit of tracing/diagnosis to determine which is at fault. Most automotive horn system works on the same basic design. A switch in the steering wheel that energizes the horn relay that in turn powers the horn(s). A self activating horn could be caused by:
1: intermittent short in the steering wheel horn button;
2. intermittent shorting out horn relay;
3. intermittent short in the wiring.

Basing on the above possibilities, diagnostic/corrective action would involve:
a. tapping on the steering wheel (not the horn button) to see if jarring it would activate the horn, if yes then the problem is with the horn switch and often cleaning the inside/contact points of the switch should be corrective;
b. tapping the horn relay with the handle of a screwdriver to determine if jarring it would activate the horn, if yes then the problem is with the horn relay which of course would need replacement;
c. the wiring would be a bit more complicated if not time consuming. It would be necessary to wiggle the wires coming from the steering wheel/column to the main harness, to the fuse/relay bank finally to the horn to check at which point the trouble would resurface. Taping any exposed/bare/scraped wire would be corrective. It should be noted that the steering horn switch often would be "to ground" meaning the horn switch is switching the horn relay by providing the negative path, the relay is constantly supplied with B+12.

There are some instances that the horn could also activated by an alarm system.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
