I had 4 chevy colorado and they all had the same problem with the horn first its sounds weak and second I have to press hard on the steering wheel for it to sound

On my Chevy Colorado 2012 LT model. I have a problem with my horn not working due to the fact that I’m not getting contact on both sides of the fuse. How do I remove the wires underneath the fuse panel to tighten up the clips so I make good contact

ACTS TOTALLY DEAD..Nothing!!!..Its wont even yry..Then randomly..ws wipers will turn on at full capacity,horn honks uncontrolably, truck then proceeds to lock you in ..or out..with nothing to get open..unresponsive to key,or fob
