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.

Is there 12 volts at either end of fuse #5 in the Junction Block (JB)? If not, you will have to work back towards the underhood PDC and battery feed (A7).
Do you still have brake lights?
The fuse #5 output is a Pink or Pink/stripe wire. Somewhere there is a short to ground.

The PDC (power distribution center) is the fuse/relay box under the hood. The JB (junction block) is the fuse/relay box in the dash. The JB also includes the BCM (body control module) on this car.
The short-to-ground may be still in the interior lighting circuit. Since the overhead map lights aren't working, there may be a problem in that circuit. Follow the Pink wire up the 'A'-pillar and along the windshield header to the rearview mirror. Do the visor vanity mirror illumination lights work?
The burned A/C control wire (?) will also have to be addressed. It almost sounds like someone may have added that wire.
No doubt that you will need wiring diagrams with color codes and harness routing information if you are going to be doing this level of diagnosis and service. A factory service manual is the way to go. A large local library may have factory service manuals or a subscription to Alldata or you can purchase a set for the car. Consider them as a tool purchase. They can pay for themselves in a short amount of time:

If everything is plugged in connector-wise to the rear view mirror and you have 12 volts at the Pink wire to it, then the courtesy/map bulbs under the clear lenses may be blown. They should gently pry off.
I'm glad that you found that 20 amp fuse blown in the PDC as that powers your rear brake lights also.
