Which fuse is linked to the horn. It is not listed on the fuse map.

Hi Bill, one sure way of finding out is doing a physical check by opening the fuse box and start by removing each fuse at a time. As one fuse has been removed. press the horn. On that fuse that has been removed and the horn does not sound, then that's the one.

How do you install a horn button on the dash of a 2002 chevrolet cavalier? From the fuse box or direct from the horn or at the steering wheel ? It is necessary for vehicle inspection in Texas?

To install a horn, Buy a horn button from any auto parts store. mount it under dash in a good place to use it. run a wire from horn connection to proper post on switch, run the other wire to a good power source, battery or fuse box. its the same principle as hooking up a light switch in a house. as long as it cuts the power to horn. it will work. There should already be a ground wire on horn itself. Good-Day!

My horn sis not working. There was trouble with my car alarm months ago and the repairman removed the after market alarm. However, my car failed inspection today because the horn will click but does not...

Yes, if a car doesn't have a working horn, it would, in most if not all states fail a safety inspection.
If you hear a click, then it could be the relay clicking or the horn trying to operate. Likely, it's just a bad horn or a bad ground connection at the horn relay.

I would take the vehicle back to the repairman and ask about the horn and repairing it, or have the inspector who failed it repair it for you.

Horns go bad on cars due to corrosion or non use over time. I've had a few go bad on motorcycles which were even stored in a garage. Opened one up one time and found rust on the contacts that made it not work or oscillate to make a sound that is audible.

I think that you could locate the horn, and see if all of the wires are physically there, and try a test light to ground it out, as horns should always have power (as long as the battery is charged up) whether or not the ignition is on.

If you ground out one or the other terminals with a test light, at the horn, then it should beep.
If not, then the horn itself is bad.

Replace with new.
It is really that simple.

I have a 1997 Cadillac Deville that wasn't used for a while and the horn went bad on it and it was replaced as one of the items required for Pennsylvania State Inspection.

My horn doesn't work, neither does my cruise control help anyone i need to get my car inspected ASAP

For inspection you shouldn't need the cruise to work but for the horn have you checked the fuse? or relay? Another thing to look for is are the wires both connected to the horn? if all that checks out check and see if power is getting to the horn and also check in the steering wheel to make sure nothing happened there.

Horn is not working, check engine light is on

your horn not working is probably due to the horn switch in the steeringwheel
