Random Honking

Here is where the horn is located; make sure the wiring harness is in good shape and the horn isn't being grounded causing it to short (water may also be causing an issue). Here is a brief description of how the horn in this car works: "There are 2 separate conditions that can cause the horn to sound. The horn will sound if the driver presses the horn switch and when the vehicle security system is armed. The horn system uses the smart junction box (SJB) to provide voltage to the horns, while the horn switch or the SJB can provide the ground to engage the horn relay. The horn switch is integrated into the air bag." Hopefully you don't have a problem with the SJB and it's just a wiring issue.
