blowing fuses

i dont have any light sockets that i can see behind my heater switch,i unplugged the round gauge connector in the cluster,and i still blow fuses,it seems to have something to do with the turning of the dimmer,as soon as i turn it all the way up,the fuse pops,the gauge lights do not respond to the dimmer as they should,they're either off or on,i've read that ther're is a way to bypass the dimmer,but i can't find how to do it.i've also unplugged the horn and buzzers
