Stop in for a cup of coffee

Trying to figure out problem on the wifes 09 Journey. Horn starts blowing intermittently just sitting in the driveway. So the likely suspects...
Horn switch- This is part of the drivers airbag as far as I know. And I am pretty sure was replace on one of the recalls in last couple years.
Clock spring - Would expect it would go off while turning if this was the problem. As far as I know,
has never happened while driving.

TIPM - For some reason unbeknownst to the normal mind. Dodge decided not to include the Horn, Fuel pump, locks and wipers among the REPLACEABLE relays. Instead they are soldered onto a board under the fuse box. :BangHead: This is a known problem. The horn is actually not a common one that goes bad because it is used infrequently. (Fuel pump is most common)
Looking for a good way to troubleshoot cause my pockets aint deep enough to change all these parts...Would be really nice to get this on the first try.
In the meantime -:steering:fuses are out and she has no horn.
You just reminded me why i drive old simple cars that I can and surely have fixed on the side of the road. If i can fix a car on the side of the eustis then anyone, because I am the last person on the planet who should be fixin a car on the side road
