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

At the extreme high end of turning the dimmer is the dome light, along with any other interior lights you my have. Betcha thats the problem.
