If one certain fuse keeps blowing, try this :
Replace the fuse with a 12v light bulb wired across the fuse connection points.
If a short was causing the fuse to blow, then the light will be bright.
Watch the light and wiggle any wiring suspected to be causing the short, see if the light goes out.
Also remove/unplug any components in the circuit and see what the light does.
