Update 9-3 So I picked my truck of from the dealer today, of course after hours bc I do have a job. I got out of the parking lot maybe 100 feet to the stop light, with my left blinker on the horn started honking on it's own. I thought it was the guy next to me after he pulled away it continued. It's not as loud as a full horn blow maybe more like a quick jab of the horn and it honks over and over! I turned off blinker put it in park and it stopped. Put it back in drive turned on left blinker it starts honking again, by this time I'm getting hot so I leave the light determined to make the 45 min trip home I get less than a 1/4 mile down the road, now the horn is honking (on it's own) as I'm driving thru town. I turned around took it back to the dealer filled out their after hours paper work in 2 inch letters (just so they would know how upset I'm getting) and put my keys thru their door. Looks like it's time to contact a lemon law attorney!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Simple short it sounds like but how many times will it take at the dealer to make them tear apart the dash to find that.
