The horn on my 2000 nissan sentra is not working. I have ruled out the fuse. How can I get at the mechanism in the steering wheel?

Disable air bags to work on steering wheel. Take it apart and replace the mechanism for the horn

you'll need to remove the horn cover on the steering wheel two screws on the bottom

that's not nice I would not want to be you when the steering wheel locked.It is possible that the steering lock mechanism has failed but is also possible that something has jammed to the system. Either in the steering box war in the steering system.
Others suggest that you get it checked properly so as not to put yourself or your family at risk.Regards

Hi, maybe when it was repaired they did not put it back on, i am not familiar with the Altima but if you ring up Nissan they should be able to help or find one thats for sale and go check it out!!!

the ground on the back of the steering wheel is probly bent

1. First check the alternator maybe you need to replace it.
2. The horn honks when you turn the steering wheel because the wire inside the steering wheel is not fix.
3. Visit a good mechanic and good electrician to check the alternator and the wirings.

Most systems have a horn, a relay, a fuse, and a switch inside the steering wheel. If you can find the horn, usually in the front behind the grille or next to the radiator, you can jump it directly from the battery with two heavy wires to see if it works. If it does not toot with power directly from the battery it is bad. If it does toot then find where the fuses/relays are by reading your owner's manual and replace the horn relay and/or fuse. Relays are generally plugged into the fuse panel too. You can visually inspect the fuse for failure. If no problem there then you are at the steering wheel disassembly and testing level which means special tools and knowledge. Due to airbag even a veteran shade tree mechanic will not venture into a steering wheel so dealer is indicated.

The horn fuse had power to it and the fuse was ok. The problem was a wire - from the fuse location - had a break.

u need a steering well puller

try turning the wheel back and forth while wiggling the key if that doesn't work i need more info.
