Question about 2003 Toyota Tacoma

My '99 Toyta Tacoma horn does not work

I think there is a connection problem. In the past, sometimes the horn would work, and sometimes it wouldn't. Just last week, I went over a pot hole, and I think it dislodged whatever connection there is needed for the horn to work, because it does not work anymore. It is not the fuse, I checked that and it is fine. If anyone here could tell me how to find, and fix this conncection problem, I would greatly appreciate it. Thankyou.

    Yea,I'm gonna have to have a friend look at it, if I can find one that knows about cars/trucks. I do not even know how to find the diaphragm or any wiring. I don't want to mess with any screws that I may find on my steering wheel if I do not know what they unlatch,etc. I tried searching online for a free manual to do these types of things, but I only found ones you needed to pay for via google search engine. So any suggestions for an online guide to help with this, would help too. Thankyou for you help.

    I went to autozone.com,found my make and model truck, but could not find anything about a horn. I guess I'll try the library tomorrow if I get a break during work.
    Thanks again.

    Mine is a 99 too, and the horn is also broken.  Does the horn have a relay in the fusebox like the highbeams do? Can't tell where the connection is broken but I'm hoping its not within the steering wheel itself

Sometimes the diaphram in the horn goes out and you have to replace the horn itself also make sure all the wires are clean and no rust

Trying to replace horn on 2002 elantra,can't find horn


Why do you have to find an OEM horn? There are tons of horns that work just as well if not better. I bought my wife a used Kia Sorento a few years back and in two weeks the horn went out I went to the parts store got two new horns a high and a low tone horn cut off the original horn plugs and put crimp on connectors and these horns are way better sounding and a lot louder than the original one. Simple job.. You'll love the results and price about 20 dollars. Dealership order I couldn't even begin to think what they would charge and I could tell you I wouldn't pay it. You can find them but they will be on order.
Good luck.

The black wire in the harness is the ground circuit. The actual ground connection is around the back seat.
If you think the ground circuit is open you can splice into the wire and ground it near one of the tail lamps.

My horn doesn't work on my 1999 Lincoln Navigator, any suggestions?


There are also relays for the horn. First check would be the connections at the horn then the fuse. If the fuse isn't blown, it's possible that the relay has gone on it. Another item to check would be the wires leading up to the horn it's self. If any of them are frayed and touching bare metal, causing a short circuit, the horn wouldn't work then.

Flashing dome light, broken horn, and slow windshield wipers... what can it be?


if your hearing a clicking sound when pushing the horn button then it sounds like you need to replace the horn the diaphram is probably no good.if it was a bad connection you wouldn`t hear a clicking noise.the slow wipers sounds like it could be a poor ground on the wiper motor.you can run a separate ground wire to the wiper body and if the wipers work at a normal speed then that is all you have to do.if not then the power wire needs to be checked for battery voltage if its good then the problem is likely the wiper motor itself.the flickering interior light may be the light switch maybe moving just enough to make contact to allow power to the light.make sure the switch is into the off position and see what happens.

My horn isn't working quite right. It only blows if you push the button in a certain place and that certain place moves around all the time. But even when it does blow, it stutters. I don't think...


if it was a fuse problem the horn wouldn`t make a noise.it sounds like the horn contacts that touch when you push on the button are not making proper contact each time.if you remove the horn button and look at the contact spots you may see the problem(uneven contact surfaces).if you move/bend the contact surfaces closer to each other of straighten this may help the problem.you may even have a horn that needs to be replaced as you said when it does work it stutters and not blow.the diaphragm in the horn can dry out and not vibrate like it should.try tapping on the horn when someone tries to blow the horn if it stops or gets louder then the diaphragm is no good.you could also check the connection at the horn itself it may have a bad connection due to corrosion and just need cleaning.

Horn stopped blowing


Sounds like you may have corroded terminals on the horn itself.

Find the horn in the engine compartment - remove the wire connected to it - clean the spade terminal with some sand paper and push the terminal back on. If that doesn't work you may need to remove the horn from the car and clean up the earth connection, i.e. where the horn is attached to the body work of the car to get a good electrical contact.
