    Default Dome lights???...03' Suburban

    For some reason yesterday after a short drive, I came home and when I opended the door to get out, I noticed none of the dome lights came on. However, the perimeter door lights DID and if I manually turned the dome lights on they would work. I also went around and opened each door to check the door contacts, none turned the lights on...it can't be a fuse since the lights do actually turn on.

    I did hear they thing have a Light Control Module, or something to that effect. Any ideas on where this box is located?

    If one of the door contacts is faulty is can "appear" open to the system. As you may know, if you leave a door open, the interior lights shut down. Once shut the interior lights resume normal operation. However if you have a faulty door switch the door appears open all the time. Try disconnecting / reconnecting the battery to reset the controller. If the interior lights resume operation you will need to isolate the offending switch.

    I don't know the location of the module, but check Autozone's website. They have a component locator that may help.

    if that isnt your problem, then you will have to locate the switches controlling your lights, and take an ohmmeter to find which one is faulty. post back with what you find, and we can help you through testing your switches if you need it

    Oh no, the override switch was not pressed.

    I did a little more research, thanks to a nice sticky on this forum, and found the module in question is actually called a Body Control Module and it control the door triggers and dome light supervision. As well, I did find a blown fuse that I previously missed, swapped it and got the dome light back functioning. Looks like it's fixed. Hopefully it doesn't keep blowing fuses...thanks for the help guys!
