Removed radio, still blow fuses for radio and i think i have a short in the harness somewere were would be the best place to look for the short
If u have a mach system there is an amp in the back in the passenger rear quarter panel,there should be an access panel to right of rear seat,pull the plug on the amp and see if its still shorting..that is usually the problem
You have a logic fuse box the nearest ground is the sun visor light,This also affect the radio so you probalby dont have the radio power also. you will have to reomve the sun visor as the wire that is shorting has gotten tangled up there

Brake sensor? Where is it located? Is it screwed in to the master cylinder?

Ok the 30 amp fuse is the switch side of the PCM relay and the W/BL wire u are disconnecting is the coil side of the relay.So when u disconnect it u are keeping the relay from energizing so this is not the problem.When u unplug the CCRM in the fender u also keep the relay from energizing.
Unfortunatley this could be the worst possible ckt to have a short on because it feeds everything with a 12V feed in the emission system.
It feeds all the coil packs,the coil side of the low and high speed fan relays and coil side of AC relay also in the CCRM.
Now looking at the schematic I think it is possible to narrow your problem down to the coil packs.The other ckts off of this go thru 2 more fuses, fuse 8 and 2 in the interior fuse panel and both of these are 20 amp fuses so they should blow before the 30 amp if the short was after them. Although it could be the CCRM I doubt it would blow the 30 amp fuse because the other feeds there are on the coil side of the relays so that leaves the coil packs.
I would trace the red wire side of each coil pack looking for a pinched wire,they will go back to right side of engine into a square 42 pin connecter.A quick way to test it is to unhook all the coil packs then get you 2 alligator clip wires and a 1157 bulb like in your t/signals. Clip one of the wires on each side of the bulb and hook one wire to power then the other to the red wire pin 24 of the CCRM that u unhooked in the fender(leave CCRM unhooked). Pull the 2 fuses in the interior fuse panel (8&2) then see if your bulb lights. If it does then u have a short in the wiring,if it doesn't then hook each coil pack back up one at a time and see if it lights your bulb.

Check the fuses for the blower motor and check power to the front switch to the blower.
SOURCE: rear A/C blows hot air instead of cold on a 2002
The most common part that fails is the temperature actuator. It is located on the right rear of the suv. The trim panel has to be accessed to replace the actuator.

The visor light still works, and I tried putting a larger amp fuse in and it pops right away, the fuse that blows is for the audio circuit 25amp
Light in visor still functioning,the fuse that blows is for the audio circuit, tried a larger amp fuse and it still pops, checked harness under dash, behind radio with no results
