07 wave, horn does not work/goes off by itself

[Rubicon]

So since I have the car for atleast one day, she would like her horn to work again. We had to disconnect it awhile back as it started to go off all by itself. Sitting at work it would just start honking ( iirc just on) so we unplugged it. We tried reconnecting it and it worked for a bit, then the same thing happened. Is this the relay? Or something else.
Thanks in advance
