I bought my 2005 Ford Escape about 2 months ago and
had no issues with it. About 2 weeks into having the car
the horn randomly starts honking. It would happen once
maybe twice a day. Then a couple weeks later it stopped.
It recently starting doing it again.
I need help. How can I make it stop without having to
spend a whopping load of money?
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.
So does the horn just start blowing or does it cycle like the alarm cycles? If it cycles then it is defently a security problem and sorry to say it won't be cheap, the tech will have to check each activation switch and the programming itself to find out if it is hardware or software causing the problem. You might try resetting the system manually, and that procedure can be found in the owners manual under deactivating security system.
