Electrical Problem - 94 Cavalier

Anybody have any tips on how to go about finding  an intermittant short on a 94 Cavalier? It is located on the CBSY circuit that controls the door locks, dome light and trunk light. I have blown 3 fuses so far. When I replaced them, they lasted a couple days  before blowing again so it appears intermittant and since its a circuit running throughout the car I'm not sure where to start. Has anyone seen this before or can point out a likely spot where the problem may be?

Thanks
