Yeah, i also have a 06 3500 dually w 5.9 cummins. My horn quit working about the same time the actuator door in the heater box fouled out on me. GTYankee s got it right with the heater treater vids. They're pretty informative.
Your problem however sounds more like a wiring issue from your description. Not sure what would allow your blower to come on even with the ignition off unless someone has rerouted the power or changed the factory wiring. Are you the original buyer of the truck? Does the truck have any power accessories that have been added that one might have rerouted power to?
