How to Replace the Horn on a 2005 Ford F150

Shares & Saves

The 2005 Ford F150 has a dual-note horn setup consisting of two separate horns that sound different notes, one high and one low. The purpose of the dual-horn system is to provide the F150 with a fuller horn tone than single-note horn systems provide. If either horn has stopped functioning, you can purchase a replacement dual-horn assembly from your local Ford dealer. If you have basic auto-repair skills and an hour of free time, you can replace the horn assembly on your 2005 Ford F150 and save the labor charge.

Things You'll Need

  • Socket set
  • Slide under the front end of your 2005 Ford F150 and locate the dual-horn assembly behind the front bumper.

  • Unplug the wiring connector from the horn assembly by hand. Unbolt the horn assembly bracket from the frame with your socket set. Lower the horn assembly from the F150.

  • Hold the new horn assembly in position with one hand while threading the mounting bolts in with your other hand. Tighten the bolts with the socket set.

  • Plug the wiring connector into the new horn assembly by hand.
