Multiple blown fuses usually indicates a failed part or a short circuit on a hot wire, not a ground.

What fuse keeps blowing ? Whatever is on that circuit is suspect and needs to be inspected or tested. The dash light not turning on gives you a good clue. A wire that has worn or cut insulation will also blow a fuse.

definitely a chaffed wire some where, tracing bad wires is some times a long boring process but at a repair shop it can be costely even with testing equipment.
Does it blow as soon as you put the fuse in? or while driving? If it blows right away look under the dash first, if it happens while driving check the wire run going towards the back end.
Do not just throw in a bigger fuse that can cause a fire, take the time to find the wire issue. Since it is wiring it could be in a number of spots to hard to say where to exactly look.

I spent 6 hours poking around trying to figure out where I had a short. Use a multimeter checking for resistance, or with a connection feature if it has one. With the power off, connect multimeter to the body and then touch the other lead to different suspect hot (but not when hot) wires. If you have a connection, then that wire is grounded and that is probably your short.

Thats how i found the wire i had a short in. I never ended up finding the actual short, and ended up running my own new wire. Good luck.
