How to Repair a Car Horn That Sticks

Fix your stuck car horn for some peace and quiet.

A stuck car horn can prove to be quite an embarrassment, especially if you cannot get it to stop quickly. And if you happen to be parked on a crowded street, it is even worse. The problems that can affect a car horn vary, so you may have to do a little troubleshooting to get it unstuck. Be prepared to take several minutes to get the horn to stop blowing if none of the easier options work.

Things You'll Need

• Car manual
• Scissors or knife
• Tape
• Wrench

Instructions

1. Press the horn again or tap it a few times. This may get the horn unstuck. If not, proceed to Step 2.

2. Turn off your engine. Refer to your car manual's circuit descriptions to learn where the fuse box is located. Find your fuse box and pull the horn's fuse. If you can pull the fuse, this will silence the horn. If you cannot remove the fuse or find the fuse box, proceed to Step 3.

3. Open your car's hood. Locate the horn. If you can see the rear of the horn, you may be able to see the wires. In that case pull the wires. If you cannot pull them, use scissors or a knife to cut one of the wires. If you resorted to cutting the wire, make sure to tape the loose end so as to not short out your car's electrical system. If you are unable to locate the horn or disconnect the wires, proceed to Step 4.

4. Locate your car battery. Disconnect the main wires running to your battery with a wrench. Doing this may reset the car horn. Reattach the wires. If the horn goes back on, disconnect the wires again and proceed to an auto mechanic to get the horn fixed. If it does not go back on, also go to the mechanic to look into the problem.
