SOURCE: 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

SOURCE: 1999 toyota avalon horn works intermitely

I would suggest to you to have the spiral cable (or 'clockspring') replaced. This is the electrical unit that transfers power to the air bag, the horn and the cruise control.

It is located right under the seering wheel.

Your description of the issue indicates to me that your spiral cable is loose, and making intermittant contact. If the vehicle had an air-bag deployment, this cable-device should have been changed.

Factory security system intermittently going off. Wondering if it is a bad sensor or switch. Does the door LED flash a code? 8 long flashes followed with normal short flashes.


CAR ALARM ISSUES


It can be any of the car doors not got properly locked or the door is locked but the switch is not sensing the door locked. Open and close each door again properly.

Or else its problem with any of switch wiring getting in contact with alarm wiring causing it to happen.

And last thing alarm connections need to be inspected. It's getting short somewhere in between.


There are few help links with solutions, to troubleshoot these types of problems. I suggest going through these links.

Alarm is programable. May have to take to dealer or possible after market shop. When battery power was lost it lost memory.

1991 Toyota Tercel horn doesn't work?


Use your middle finger.
Or, do you hear a relay click when you press the horn button? May be the relay went bad (dirty contacts inside). Or possible lost connection behind the horn button.

The fuse have been change in the 2006 toyota avalon and the horn still don't work hoe do fix it


Check your horn relay and the wiring going to it. If they're in good order, the horn may have shorted out (hence the blown fuse) and need replacement.

Toyota avalon 1999 horn does not work does steering wheel come off to look at it


You could check if current runs to the horn wires when the horn switch is pressed. If ok, then the horn itself may be old. Next thing is the fuse, the grounding source, the horn-wire plugs.
