Dash lights dont work and main light fuse keeps blowing Help!

[Blackone51]

My dashlights don't work anymore, and found main light fuse bad but it keeps blowing. Anyone have this problem? I'm assuming a short somewhere, anyone have some diagrams I could use. If the headlight switch is bad will the fuse keep blowing?

Thanks much

OK haven't looked at the mustang but found out the brake lights also don't work, assuming part of the fuse (main light fuse). I don't have HID's so don't think I'm drawing to much power, I think I have a short somewhere. I actually heard when it happened, I pulled the light switch and heard a pop. Ever since than no dash lights or brake lights. Could a faulty light switch keep blowing the main light fuse? I was told it has an automatic reset or something? Any ideas would be great!! I love my mustang but its been one bad summer for stuff breaking or not working.
