Three problems related to horn assembly have been reported for the 2006 Dodge Ram 3500. The most recently reported issues are listed below.
Turn signal eradicating going from normal left working to fast on dash but no exterior left front or back then changing to right working then back all when left stick is engaged also horn beeps once or twice all the time while driving or parked while runninig.
Takata recall - when they replaced my driver's side airbag they broke the electrical substrate (in the airbag cover) that functions the horn. Apparently this is happening on most of these as the part is on back order. I haven't had a horn since may 2016 and have almost been in a wreck as a result.
As I was driving down the road to work I turned on the blinker and a bell went off, then the windshield wiper started spraying fluid on the windows and the wipers would not work. I was 2 blocks from my office and pulled in and turned the engine off. When I exited the vehicle a smelled what smelled like electrical fire. I opened the hood and noticed smoke coming from the fuse box. I went into my office and was getting ready to call for a tow truck when I heard the trucks horn started honking, I ran outside and the vehicles lights were flashing on and off and the truck was starting running and then turning off all on its own with out a key in the ignition. The smoke was really pouring out and the started kept trying to start. I disconnected the batteries and removed the fuse box. This is a serious safety issue and I have read numerous blogs regarding this problem this morning. Thank goodness I was stopped in my office parking lot when this happened as if I was going down the road this could have killed someone.
