that is good information to know about the interior light coming on.... there is a short in a door. and what thatmeans is that in said particular door the door pin wire could be grounding out as well as the speaker causing the stereo to shut down. when you say that the radio takes a crap on you does it stay on and the sound just stop or does it completly go out? give me a shout through email
