Electronics going haywire!
I'm not sure if this has been discussed I did a search.So while I'm coming down the interstate headed home my headlights and high beams come on all of a sudden,when I get home and pull in my horn starts blowing and stays on I pull in the parking spot it stops,when I take the key out and pop the hood the horn comes on and stay on.Only other things I noticed my turn signals didn't work I can't even troubleshoot due to the blasted horn.Has anyone had this happen before?
Re: Electronics going haywire!
I've seen other issues with the electronics due to faulty ignition switches and multifunction stalks but I've never seen the horn involved in any issues that weren't related to the factory security system. First thing I'd try is using your other or second programmed key if you have one.
