Illumination fuse keeps blowing out

[VicYukon]

Illumination fuse keeps blowing out evreytime i replace it. Parking lights turn on evreything goes on except the dashboaed lights cluster, and ac controls. It has a aftermarket stereo that i had to rewire some wires cause you couldnt hear the left speakers. Thats the only thing that i can think of effecting it please help guys, thanks.

disconnect the radio and isolate it as a cause. did it happen just right after the speaker repair. while you are at it pull the hvac controller and ip cluster replace fuse and if all is good put in one at a time. if it blows again before putting those items back in we just eliminated about 70-80 percent of devices with little left to check and the actual wiring.
