    2010 Pursuit - Is horn fused?

    Horn has never worked for me in 2010 Charger Pursuit. I suspect it's some disconnected siren that had been wired to it for clearing intersections. Horns themselves tested and working. I've gone through front fuse box, and rear PDS, as well as manual, and it does not list a fuse nor a relay for horn. Is it possible the horn is not fused/relay? Seems odd.

    I think it's on the same as the AC clutch.

    I did Ev installations for awhile. They will typically cut and splice somewhere under the steering column for the horn ring on the siren. You’ll need a wiring diagram but that’s a good place to start since that’s the typical cut location.

    Start tracing wires or the wire if you have a diagram looking for anything cut.

    I have a 2008 Magnum and a 2010 Charger. They have the same electrical system. From the service manual:
    The horn button provides a closure to the Steering Wheel Control Module (clock spring). From there the horn signal is data to the Totally Integrated Power Module (front fuse block). The TIPM provides a high side signal (12 volts) to the two horns. The ground on the horns is the mechanical connection to the cross member.

    You can check to be sure there is a closure on the horn switch by checking the connection into the clock spring. - Take the ground off of the battery, go have a cup of coffee. Take the airbag off the steering wheel, disconnect the horn connection. Reverse to reassemble.
    You can check to see if there is 12 volts at C1 (black) pin 3 when the horn button is pressed. - If there is voltage, look for an open in the wire to the horns, or a bad ground.
    You can run 12 v (battery) to the input side of the horn with the connector disconnected. - If this does not work, clean the ground connections on the horns (the bolt).

    Good luck. Steve

    Thank you both. I was hoping to start with "easy" thing, being a fuse, but I guess not. I will try those things. Thank you both. Larry.

    I follow the wires from the siren to the wires on the horn about 6" apart you will see where they made the disconnect.electrical tape on the wire harness was a dead giveaway. good luck.
