2000 - fuse problem -Indicator/radio/dome

Suddenly one day radio went dead while drivng. Then indicator stopped working right after. Checked fuses under hood/sig.lght fuse(15amp), int.lght fuse(15amp) both blown. Also interior fuse box/radio fuse(10amp) blown
New fuses intstalled, blown again. Keep on blowing. Had 2 x's diagnostics done, and nothing comes up. With new fuses, the signal lights can be heard thru the radio speakers. Where to start???????
