Well its always something! Tonight I get in my truck and start. When I turn on parkinglight/ headlights the horn sounds. This also happens with engine off. I gave the truck a good exterior rinse today but did not go under hood. Have any of you ever had this gremlim? Everything else seems fine and horn works normal when lights are off. Any help would be great! Pete

 

That's definately strange. when you sound the horn, do the lights flicker? sounds like you got a short under the hood somewhere

 

As I had mentioned in first post, I had rinsed pretty good the frame and undercarriage blasting the hose up into fender openings to attempt to remove road salt and got a connector wet causing horn problem. I'm dry again and my neighbors are dropping all charges. Thanks for any and all help! Pete
