Chevrolet: electrical??, courtesy lights, camero

Question
i have a 95 camero LT1 3.4.
I WAS DRIVING AND I HEARD A POP AND MY FUSE BLEW TO MY COURTESY FUSE (15) . BECAUSE IT BLEW MY RADIO, DOME LIGHTS, TRUNK BUTTON AND COURTESY LIGHTS WONT WORK. I REPLACED THE FUSE 15 AND ABOUT 3 MINS BLEW AGAIN, SO I TRY A 20 FUSE AND IT BLEW IN LIKE 30 SECONDS.I KNOW IF YOU PUT A TOO HIGH OF FUSE IN IT IT CAN FRY THE WIRES. SO I THOUGHT THERE WAS A SHORT IN THE SWITCH TO TURN MY DOME LIGHTS ON, WHEN I PUT A NEW FUSE 15 IN  AND SWITCH DOME LIGHTS IT BLEW, NEXT DAY I DID THE SAME THING AND IT DIDNT BLOW DUE TO THAT I DID NOT DO ANYTHING AND IT BLEW. I HAVE TALKED TO MANY PEOPLE WHO ARE MACHANICS AND THEY DONT KNOW WHATS WRONG WITH IT. PLEASE HELP.

HI;
OK so everytinng is fine now ? if so you could have had something stick or a wire could have been shorting out as it could be anything, but never try to put a larger fuse in place of the size that was in it as it can or will burn out something on you. I would check all wires in trunk and lights and all that are on that circut  give it a good look over.You might have just lucked out but still something did cause it to happen so look it over good.  ok
