You may need to put a relay in it as the current from the horn may be back feeding up the immobiliser horn circuit and causing a short. Sounds like the immobiiliser has its own source of power seperate from the factory circuit When you press the horn the power goes to the horn and up the immobiliser horn circuit and it blows the fuse.

    Have you put a new fuse in activated the immobiliser and checked if the fuse has blown or stayed intact?

The most common cause of this short is the horn coil, replace the horn and the problem will be fixed, a quick test is to disconnect the horn and press the horn button, if the fuse doesn't blow the horn is the problem.

Horn doesn't blow. i have changed the fuse. it only blows with remote key lock


Should be clear that the problem is in the steering column horn mechanism, but to fix it you will need to remove the air bag.. Are you competent to do that safely?

Horn relay


my guess, its a dead horn? both dead?
no actual question asked????????
the fuse is blow? in fuse box, eng. bay box.?
if no power to horn, (voltmeter)
we check power in and out of relay if there is one.
then at the horn button wire, (air bags can kill any mech. defeat them
first if heck bent to fiddly steering column parts in any why)
all this info is convered in in the FSM, get one. or login to alldata dot come. and read it.
here, ill look at yours. now.... a fast look.
ok 2 horns, hi/lo, and 1 relay in the under hood fuse box.
it should be labeled in the box, HORN
the relay can not work if the fuse is blown
or the horn enable line is dead. button.
the button grounds (0v) the relay via wire color lt.green-blu pin a11 on relay. if the a11 is at 12v the fuse is good.
if you push the horn button this A11 goes from 12v to 0v, and the relay energizes (click) and the horns both blow.
if no power makes it to the horns, the relay is bad no 12v
if by chance the relay output to horns go to 12v, then the horns are both dead.

Horn does not sound when locking car with remote


Will the horn sound when you press on the horn button? Sometimes fuses, or relays in the electrical system fail. If no horn sounds when you want it too, check the under hood fuse block, or interior fuse panel. Normally on the back cover of these two places identifies which fuse or relay works what. Check horn fuse to see if it's blown first,than have the relay tested. Just basic info, but it's where I would start.

Horn dosen't work


Check fuse. Usually located under the Steering wheel or under the hood. You will have to use the other side of the cover to determine which fuse controls the horn and see if the metal link is broken. If both are not blown its probably a short in the wire. If it randomly just happened then its a good first guess without knowing any further details.

Usually I check all my fuses any time I am looking for a specific one. Sometimes a random fuse can be the cause, and not the actual Horn fuse that is blown.

I just bought a 2000 Saturn SL 4-dr sedan. It's in great shape, but the horn doesn't work and the dashboard light don't work. Is this a simple fix with replacing the fuses or dash light or is it a little...


Check fuse for horn and for dash lights. If the interior lights work then suspect dimmer switch for the dash lights. If you press the horn button do you hear a click under the hood or inside the car? If you do not then the fuse is blown and if the fuse is good then the relay may be suspected bad. If the fuse is good and the relay clicks then suspect the horn to be bad. If fuse is blown and you put a new one in and you push the horn and the fuse blows again, then disconnect the horn before replacing the fuse again. Then push the horn button and see if you hear the relay click if you hear a click the the horn is bad or wiring butmost likely the horn. If you have the horn unplugged and the fuse is good and you push thee horn button and no relay click suspect the horn button to be bad. Hope this helps.

The horn on my 2004 Grand Am gradually stopped working. (When using the remote to lock the doors, sometimes the horn would barely bleat, at other times it sounded fine.) Fuses and connections seem ok....


no, sounds like its time for new horns, have someone push horn button while you check for power at the horn, if theres power then replace the horns,sounds like bad horns to me,good luck.

The horn does not work , the fuse is ok .


Does the horn blow when you press the horn button on the steering wheel? If not I would first check the horn fuse ... then check the relay Swap it with a like relay (keeping in mind whatever you swapped it with won't work now if it is bad, or intermittant) ... owners manual will help with the locations of these.

Find horn, remove wire connector from it, try new fuse, push horn again, if fuse blows, you have short somewhere between, if it doesn't, it's the horn.
