What happened! horn doesn't work, antenna stuck in up position, temp controls reset when i start my

Try connecting power directly to the horn and see if it goes off. If not, it would seem it needs replacing. If it works, maybe the horn switch on your steering wheel is broken. A simple process of elimination.

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.

Do you mean the control lever is stuck, or you move it and nothing happens ? If the lever is stuck you would pull the control panel out and check the operation. Most of the models used vac to move the blend doors.

I would start with checking the blend door under the dash that controls temp.

When the battery was disconnected, the HVAC system lost its calibration or one of the door actuators is stuck. With truck on, set all HVAC controls and switches to their OFF or CCW positions. Disconnect the battery, wait about 3 minutes, then reconnect. Turn ignition to ON position, doesn't need to be started, and don't touch any of the HVAC controls for about 3 minutes. This should reset the calibration. If this does not work, a mechanic will need to diagnose the problem.

The horn is located at the front of the vehicle near the radiator. Before you even look at the horn, check the fuse - the horn has its own fuse. Then check the horn relay and then the horn. Lastly, if the horn still does not work check the horn switch/button

You can do this for now so its not driving you crazy, then get it fixed.
If your car horn starts blaring and seems to be "stuck" (it won't stop blowing), you could be in for a few embarrassing moments. There's nothing quite like the stares and expressive hand gestures you can draw as your horn takes on a life of its own. There are a couple of things you can do to get the horn to stop.
If it got stuck when you pressed on the horn switch on the steering wheel, it could be because the switch itself is stuck. Press the horn switch again, or tap it a few times to see if it gets unstuck.
Turn off the engine and look for your fuse box. Look through the circuit descriptions and see if you can find one for the horn. If you can, pull the fuse. This should silence the horn immediately.
If you can't find the fuse box, can't remove the fuse, or the horn doesn't turn off, then you need to resort to more drastic measures. Open the hood of the car and try to locate the horn. If the rear of the horn is visible, you might be able to see the wires that lead to it. Disconnect the wires. If you can't disconnect them, then cut one of the wires. If you cut the wire, wrap the resulting two ends of the wire with tape so that they can't short out your electrical system.
You could disconnect the main wires that run to your battery. You shouldn't cut these but should disconnect them using a wrench. This might "reset" the horn. Hook the wires back up and if the horn doesn't turn back on, you should go directly to an auto repair shop to figure out what is going on. If the horn does turn back on, you'll need to locate and disconnect (or cut) the wires to the horn as previously described. Then, go to the auto repair shop and let them replace the horn for you.

• The horn relay might have welded contacts (stuck in the on position). Pulling the relay should stop the horn.
  
• The wiring harness on the steering column might have a broken wire to the horn relay shorting to someplace that applies power to the relay. In this case, turning the steering wheel all the way to one side or the other may stop the horn, and it won't sound when you press the horn button.
• The horn button in the steering wheel is stuck on or shorted.

the diverter in the hvac is possible stuck. Cycle thru all vent position see if it un-sticks. Is the blower strength the same on both sides. What happen when you are not in dual temp control mode?

the heater doesn,t work blows cold air
