Question about 2002 Toyota Tacoma
I have an intermittant problems with my 2002 Toyota Tacoma Extended Cab. Sometimes the horn will blare on the truck unexpectedly, but only when the lights are on. The horn will stop when I shut off the lights; this is a problem when I am driving at night. As a stopgap measure I simply removed the fuse for the horn. The dealership cannot reproduce the problem. Any thoughts?
Rewire your horn from the steering wheel to the horn. Its not difficult, I can't tell you how to take the steering wheel apart but you can get a Haynes Repair Manual. It'll have all you need and more. You can use speaker wire, split it in two. Run one cable from the positive in the battery to the horn switch in the steering wheel. Another from the switch to the horn. You have a short somewhere, to me is easier just to run new wires than to find the short-circuit. Make sure when you run the cables through the firewall you run through a grommet so it does not get damaged by metal. Before anything check your headlight wires that they are not touching the horn.
