    WE HAD TWEETER INSTALL THE RADIO AND CIRCUIT CITY INSTALL AN ALARM, NOW THE INTERIOR LIGHTS DON’T WORK. WHEN WE ASK EITHER PLACE THE BLAME THE OTHER.
    RADIO WAS A ALPINE WITH iPOD INTERFACE AND THE ALARM WAS PYTHON WITH THE AUTO DOOR LOCKS.

    Mike,

    The first thing we would suggest is that you pull and check every interior and exterior fuse to make sure they are good. If any of them are bad, replace it with a new one. If they are all good and you still have this problem, let us know by replying here and we’ll proceed to the next step.
