Man, this is going to be a hard one guys. Last week the radio blew the red 10 amp in the inside of car's fusebox..Its the #5 one, says int lamps-radio mem. Now, when it would blow the radio would not show the time when it was off or come on at all. I'd slap a new one in and it'd work for a week or less even. But no biggie, just pop another one in and back to normal. Well, now I got some problems. Other day I put one in and it worked for 10 secs and blew quick this time. I got mad and threw another in and this time it blows basically right in my fingers. I get mad and go through a box of about 12 or so more. They keep popping in my hand right when i barely get em in. And now the rearview map lights dont work. And also now, the keys have to be in the ignition with the key turned to the one before it cranks for the trunk button to open the trunk or the key fob to unlock or lock the doors. I tried 3 other radios and none come on so its not the radio. Also, the fuse doesnt blow anymore. No fuses are blown in the entire fuse box in the car. I also switched the bigger two silver ones in the fuse box and the big black square one just for heck of it. I get em almost free so i just tried that but that didnt do a thing. Its weird, now the fuse doesnt blow at all. half the interior dioesnt work now either and the keyfob doesnt work unless ignition is turned on. Any ideas ya'll. Im in trouble over here. I have that 25 dollar meter from Advance. That black one.

Yeah, that circuit is more than just the radio. I'd start by examining the other systems mentioned to see if they are working. You've got a short somewhere, it's just that you need to find it.

My guess would be one of the lamps or the amp, as they tend to be the cause of these issues...

Anyway, there are two fuse boxes on this car. Have you checked the fuses under the hood? If you blew one of them, it will kill the circuit but not blow the interior fuse. So, do you have any blown fuses under the hood?

Bob is right about that. Your short is most likely somewhere else. It that ground cable is not connected though, you will have issues with the radio - like the clock losing time, and radio stations not working, and a few other things could happen.

Anyway, to interprate the diagram it helps to know what you're looking at:

The "C#" notations are connector numbers. The numbers next to those notations are the pin locations of that wire within the given connector. If you had a factory service manual, it would show you exactly where that numbered connector is.

The "S#" notations are splices.

The three lines of letters and numbers in each line (which represents a wire) are the subsection of the wiring harness, the guage of the wire, and the color of the wire. (PK/WT is Pink with a White tracer.)

The dashed squares indicate areas where other sub-circuits or systems exist.

The circles with x's in them are bulbs.

Completely agree with ImperialCrown, the FSM is the way to go, especially if you intend to keep the car long term.

However, while you're waiting on your FSM to arrive, go here:

There is a very nice wiring diagram section there for that car, which may help you out quite a bit.

BTW, which fuse was blown?
