Well it's 4:30am here in Missoula, MT and -10degrees outside! And for some darn reason the horn on my 1998 k2500 woke me and all the neighbors up at about 4:00am when it some how turned on itself and was BLARING!!! So I ran out their in my boxers to disconnect the batteries to turn the gosh darn thing off. How the heck does a horn start blaring on its own??????? Does the cold have something to do with it like the cold somehow makes a connection in a switch? Cause come tommorrow morning in gonna have to reconnect the batteries and knowing my luck the horn will be blaring again. Has anyone heard of this!!!!!!!!???? This truck never ceases to amaze me.
