Check your horn relay to see if you can't find the wire that goes to your horn. If cant find it you can bypass your relay and connect the wire directly to your horn switch located on your steering wheel.

Horn hook up


You have two wires going to the horn? Just plug them into the horn. If the horn still doesnt work switch them around.

Horn on 2000 toyota camry not working!!!


Your horn circuit is very simple. It consists of the primary circuit, which controls the relay coil and the secondary circuit that applies voltage through the relay contacts to the horns.

The Horn fuse (10 Amp) in the engine compartment fuse block supplies the battery power for both the primary and secondary circuits. This fuse is haot at all times (regardless of the ignition switch position).

Battery power is supplied to Pin 1 of the horn relay. Pin one of the relay connects to both the relay coil and to the secondary main contact.

The ground for the relay coil is provided via the GREEN/BLACK wire through the horn switch. If the relay is clicking when you push the horn button, then the primary side of the horn circuit is working.

When the relay coil is grounded by the horn switch, the relay contacts come together (that's what makes the clicking sound) and supply voltage to the GREEN/WHITE wire that connects to the horn assemblies.

Check for battery voltage at the horn when the horn switch is pressed. If there is no battery voltage present, then the only thing it can possibly be is dammaged contacts in the horn relay or the GREEN/WHITE wire is broken between the relay and the horn.

If there is voltage present at the horn on the GREEN/WHITE wire, the only possibilities are bad horn assemblies or a bad body ground that is not allowing the horns to ground properly. A bad ground condition can be verified by running a jumper wire from the battery NEGATIVE post and connecting it to the mounting bolt at the horn. If this makes the horn work, then you probably need to repair your body grounds near the battery.

My 1995 toyota camry horn works sometimes


Most horn sytems on vehicles have power to the horn, and the horn
button simply completes the circuit to earth.
Check to make sure the earth lead bolted to the front panel is clean and tight, check also that there isn't a horn relay under the fuse box cover, it may be faulty.
You will need to make sure that at least one of the wires to the horn has 12 volts going to it, if not, the fuse may have blown.
Hope this helps.

Your problem is most likely a defective clockspring assembly. This is also called "spiral cable assembly" it is located just under the steering wheel on the steering column and makes the connection between the main wiring harness and the circuits for the air bag and the horn. I cannot give you wire colors because your question did not mention year, make, model, engine size or whether the vehicle is equipped with cruise control or not. (cruise control makes a difference in the clockspring assembly used on your car.)

Anyway, the air bag and steering wheel has to be removed to fix it.

pull your steering wheel horn pad and check the spring wire to make sure it's not grounded anywhere.

Horn doesnt work


The fuse can't click it is probably the relay that is clicking. Check fuse #2.37 it is the 12th from the bottom row of the central junction box from right to left if it is ok ground the dark blue wire coming down from the steering column to check the horn pad and ground. If the horn works you have a problem in the clock spring or ground. If it doesn't check for 2 pins at the horn relay in the central juntion box for 12 volts if you have 12 volts at 2 pins with the key on then jump pin 30 of the relay with pin 87 of the relay and see if the horn goes off if it does have someone press the horn pad and see if you get a ground to pin 85 or 86 of the relay if you don't you have a ground problem to the relay if you do the the relay has failed. If you jump the relay at the central jumction box between pins 30 and 87 and the horn doesn't go off then the horn has failed or isn't properly grounded. Then check the horn for power with the horn pad depressed if there is power at the horn connector. Hold a test light on the ground wire for the horn from the ground of the battery and see if your test light shows power if it does then you have a bad ground to your horn if it doesn't then your horn has failes.

My 99 Toyota Avalon horn does not make any sound.


save yourself the hassle , buy yourself a momentary 12volt switch drill a nice clean hole on your driversside dash and re-wire your horn to it, all the screwing around you'll do to figure out why toyota makes cheesy horn contacts you could have your problem fixed..



on one side of the switch you should run a wire that is a 12volt switched +
on the other side I would run another side run a new power wire to your horn
leave your horns stock ground and just replace the HOTLINE ..

you could even go as far as installing a la cou ca racha horn to bring back that 70's Lowrider feel lol
