First my interior light went out, next my dash lights and now my tail lights have gone out. The head lights and brake lights still work though. I checked all of the fuses inside the car and they are fine. I looked under the hood and there was a 15 amp fuse blown. I put a new one in and it immediately blew. Plz tell me what I need to do to fix this problem.

 

something is grounding out. Got to find that gorund or you will blow that fuse all day long
