Been chasing this around for a while and its now back again. Car will go dead within 12 hrs when it decides to. Ha. Did draw test on battery fulling fuses and such. Car acts normal starting at 4.5A draw and slowly drops down to .18A as systems boot up. Started with new battery just to get that possibility out of the way. Heres what ive found after sitting for some time the draw comes up to 2.5A briefly then settles back to 1.18A. It will continue to cycle up and down until door switch is opened. As it does this the speakers hiss. Shut the door it settles in as normal then will start its chaotic cycling again. Pulled amp fuse drops about .5A. Pulled radio fuse and it will drop to the 1.18A. Now 1.18 is still to high in my opinion with no key in ignition. Pulled BCM logic fuse and draw will settle back in at or around .18A. So i dont want to throw parts at it and was curious if anyone else has had this and what module could cause this or possibly amp or radio malfunction.
