check the fuses..
its rubbish!!
check the fuses
Check the battery. Seems odd but give it a jump and it should start.
Likely, check the fuse panel for blown fuses. if this doesnt solve the problem you likely have a short in the wiring under the dash. you also should check the bulbs for the interior lights, its also possible you have them switched to off, where they wont come on at all. check the one in the center of the vehicle to see if it has a switch, if it does make sure its set to DOOR, check the fuses and bulbs, then if these are all set and it doesnt work have a mechanic check your wiring.
Have you tried turning the knob that turns your head lamps on? Sometimes that will turn your interior lights back on. Also, you might check the fuse box that is located under the dash on the drivers side, there may be a fuse blown.
The IOD fuse feeds the interior lights, radio, and other interior items.

Have you tried pushing the button to the left of the steering wheel? the one that shuts the lights off when they are on. if that doesnt work, if you have an aftermarket radio, and the adapter for the security, that might be why.
