The Horn in my Cadillac doesn't work. When i first tried to fix the problem, i checked the fuses, and sure enough, the horn fuse was blown. I changed the fuse, and still nothing. I also checked to make sure it didnt blow the new fuse (it didn't). One thing to note is when i tap the horn, it makes a noise, its like a click, with a small hint of horn lol. There is another fuse for the horn, but its one of the big ones that you cant check. if you guys have any ideas, let me know. Thanks :)

Re: Horn in 1990 Cadillac Seville doesnt work
If you hear the relay clicking,and even faint horn, check the connections on the horns themselves, there are probably two. If they seem okay then take a piece of wire and jump from +power to the horn terminal. Be prepared because if it works it will be very loud, and I know more than one person who's hit his head on the hood doing this. If it doesn't work, replace the horns. Hope this helps. Cheers.

its probably your alternator i would start by testing that im pretty sure advanced can test it for you. also test your battery because when the alternator goes it will run off of your battery and drain it if that doesnt work out for you then your going to have to provide me with further symptoms
check horn fuse or relay in fuse and relay box (under hood). The fuse you can visually check by looking for a blown metal strip in the fuse (use chart on fuse box lid for labels). relays are more difficult to explain how to test. but they are cheap. you can try buying a new horn relay and installing it. after that, if it still doesn't work there could be a probably with the switch in the steering wheel. if it is i recommend you take it to a shop to diag and fix. worst case it could be a bad horn and/or elctrical wire and connection. A local shop could fix this. But check the horn fuse and relay that more than likely what it is.
The fuse block is located in the glove box behind an access panel on
Eldorado and Seville. There are 2 fuse blocks on 1992-98 Eldorado and
Seville, one located in the left-hand side of the engine compartment, on
the wheelwell and the other is located on the side of the trunk. To determine if a fuse is blown, remove it from the fuse block and
examine the fuse element for a break. If the element is broken, replace
the fuse with one of equal current rating.
You will need to test for power on 2 terminals, ground when the horn pad
is pushed and if you jumper power to the horn wire the horn should
play. What doesn't work will determine what needs to be fixed. There are
bulletins that deal with the air bag in the steering wheel as being a
problem so if you don't get a ground when the horn pad is pushed then I
would suggest taking it to the shop and have someone repair that part of
it because serious injury can result if propper steps aren't taken to
disable the SIR system before disassembly. Also some special tools might
be needed depending upon how deep into the column you need to go.
Does it have a security system? If it does see if the security light is flashing. If it is you can reset most cars by turning the ignition to on and waiting for the security light to go off. Then it will start. This will happen again.
Is the horn not working? If so there is a horn rely that can be bad (to check it find a quite place with the car off, push the horn button down if you hear a click and the fuses are ok but, then you'll need to check the rely it self test light will work good for all the test, then there the wire going up to the horn button both will be under the dash that can be broken.
