Default Radio and Dome Light Won't Turn On

So I was at my Aunt's house for a party a while ago and I think I left the dome light on in my car all night. The next day when I went to leave my radio wouldn't start and I noticed the dome light was on. Now it's been a few weeks and the dome light won't turn on either. My lights on my dashboard work fine. I checked the fuses they seemed to all be fine. I did but a new stereo system in about a year ago. Anyone have any idea what could be wrong with it?

Both the radio and the dome light aren't working. I've tried turning the dimmer switch all the way up and still the dome light doesn't turn on.

the power to the courtesy lamps is provided by the bcm. which fuses did you check? the radio/interior lamp fuse that supplies the bcm.

Base, manual locks, and windows. I checked all the fuses just to be safe

which fuse panel did you check? you need to check the circuit I listed above at the i/p fuse box.


check for power to the bcm at the orange wire, connector c2 pin 12


check at the radio connector c1, pin b1, orange wire for power to the radio.

He said he checked all the fuses. I'm assuming by I/p , you in panel the fuse box on drivers side of the dash. What is the BCM I know what the PCM is ? Just for heck of spray some contact cleaner into the door switch or WD40. Does the doom light come on when u put the key in the ignition?

have already confirmed the master switch won't turn the light on....so whats the door plunger going to do...nothing as its an input to the bcm, not the light itself.





I have to ask about the fuse in question because so many times people say they checked them all only to find out later they were at the wrong fuse panel. this fuse powers the bcm which powers the radio and dome light, both of which are inop.
