Crysler Pt Cruiser 2003 Limited Edition...problems with horn and radio.?

So the radio started to go in and out randomly, while I was driving. Then I noticed that it would work just fine if the key was turned in the back position. But still sometime for days I couldnt listen to the radio while I was driving. Then one day I tried to beep the horn and found that it was unsusually hard to blow...so I hit the steering wheel hard a few times until it blowed and the radio came on. Now evertime the radio goes out while I am driving...I just hit the horn...hard...Cause a little push wont make it blow and then the radio willl come back on...but then the radio goes out again and then I have to beep the horn again...it's a never ending cycle.

So what the heck is going on with my car. I bought it as is...and I love my car...it is my dream car...but I dont want problems with it all the time. I've only had it a month. Can anyone help me out please?
