I have a 2007 expedition and last night the horn was randomly honking it started just once on occasion. Then this afternoon it went off constantly and wouldnt stop even with the remote. I located the push button under the dash I assumed it was to reset the anti theft sytem but the horn kept going off. Has anyone else had this issue? Any help will be greatly appreciated. Dont know what else to do besides go to an alarm shop or ford dealer.

 

Push button? You must have an aftermarket alarm installed. It maybe malfunctioning.
