Stereo & Electronics - Cluster Dimmer Fuse...

For some reason the fuse for the gauge cluster dimmer switch keeps blowing. I've put three 5A fuses (checked and double checked its only a 5A socket) and even a 10A fuse because it was the lowest one I had while on the highway at night... and it blew that one too. I already need a new BCM I'm pretty sure, could this just be a related problem?

i don't know much about wiring but when my head unit wires touched copper to to copper it would turn the gauge cluster on and sometimes blow but it was because someone jacked my radio so it was like that till i hooked a new one in today
