Good day
It had rained all night and was still raining. I noticed the headlights were on in the morning on my 1999 F250. I went to the truck and witch was in the off position. I turned it "on" then "off" and the headlights went off
8pm that evening the honk started honking. I used the key and started the truck , it started okay but horn wouldnt stop. So I disconnected the batteries.
Are these problems related? Where should I begin looking?
Thank you

First place I’d look is the GEM module getting wet from a leaking windshield
