Horn sounds when battery put back on dodge calibre

First I'm not a Dodge mechanic.
* Check your warranty. Call for setrvice.
*** following is for information only.***
* horn switch is stuck. See if you can pry it back up.
* For multiple horn switches (both sides of steering wheel) check both switches for "mushy operation" or stuck in one position.
* Horn RELAY not working (all makes); https://www.youtube.com/watch?v=76xR7QGPF1M
* The drained battery is probably due to a short in the electrical system
* Pull the "Horn" fuse to stop the horn (or pull out the horn wire to the horn itself. Leave it disconnected until you can confirm the bad switch or a short in another part of the system.

Aloha, ukeboy57

first thing to check will be the horn operation. Older horns rust up in the operating mechanism in the horn. Get a replacement horn and put it in place nd see if that is the problem Check for power to the horn as the fuse or relay may be out.

I would say a new horn

Put battery voltage directly to it
& see if it works

If it made any sound-- how could it be a fuse ?

If it was a fuse, nothing would happen & a new
fuse wouldn't do anything, until you found & fixed
the reason a fuse failed

You may of forgot to plug back in the ground wire that connects to the horn bracket under the air bag. It's just a single wire and should have a tiny black connector on the end of it.

if you check the wire that comes from the horn button to the relay for voltage when the horn is pushed and have voltage then you have a bad relay,if not then you probably have bad contacts in the horn pad area or even the clock spring itself.

get used horn at junk yard sounds like the switch on the door jam that pops up when you open thye door is bad check it before you go to junk yard some times they just need the electrical contacts sanded shiny get a cheap voltage test light at the parts store its worth millions

Sounds like it. Can't you take the horn pad off.

for the horn there should be a relay in the fuse box in the engine compartment near the battery. it has likely failed.

for the back up lights. put it in reverse and "jiggle" the shifter and see if they do in fact go on.

check fuse and then check ground to the horn
