1987 toyota pickup horn problems


My 1987 pickup has a broken horn too. I looked into it and think I know the reason. The steering wheel has a little pin that rubs up on a metal disk, and this pin and disk are what supply the battery voltage to the horn button on the steering wheel. I can see a small gap between the two. The pin appears to have been worn away just enough that it doesn't make contact anymore. If I shove a piece of metal into the gap my horn will work. I need to replace the pin.

2003 POTIAC SUNFIRE HORN DOES NOT WORK WHAT COULD BE THE PROBLEM?


HI. The first check point will be the fuse. make sure that the fuse filament isn't severed. This is common. If the fuse is in good condition, move onto the wiring and horn device. There may be a disconnection at the horn connection point. You can also test the connection wires for shorts, as well.

More than likely the actual horn may need to be replaced if the wiring and fuse prove to be in good condition. A basic multimeter can be used for the wire test, if you have one.

NOTE: In rare cases, the horn switch in the steering wheel could be the culprit, although, highly unlikely in most cases.

The horn button on the steering wheel is not working on a 1998 sunfire GT


  • Check the fuse first and if the fuse is good checked the connection of the wire in your horn button and make sure that the negative wire is properly connected.
  • After you perform this and still the same check the horn maybe the connection on the horn is not properly connected.
  • If you have additional questions feel free to reply to this solution.
