The interior lights wont turn off even when the car is off. What should I do?

Battery can still be dead, but have enough power to power the interior lights. Won't have enough juice to crank.

Probably bad headlamp switch. You do know most have a position which turns the interior lights on even with the doors closed, don't you? If you have this turned off, but lights stay on, replace the switch.

If your interior lights are not turning off, you probably have the override switch turned on. This is located in front headliner area and has a light icon on it. This switch forces the interior lights on, even when all of your doors are shut, or if you are driving.

Check the fuse

Even though all of the interior lights up there still isnt enough cranking amps to strart you vehicle.

Obviously you've checked light switch dial or whatever to make sure it wasn't inadvertently turn on by someone. There should be a small button like or pin like switch on door posts (where doors meet body), that turns interior lights on & off as door opens & closes. You should be able to push them in with your finger or thumb. Try one door at a time, and push it in as far as you can & see if interior lights go out, even momentarily. You may have pin style switch near hinges, so look there too. Let us/me know what happens, if anything.

Providing your switch isn't turned on?? it is probably something to do with the switch in the door jam. It might be loose or just not doing it's job anymore. Sometimes even electric door locks can cause problems with interior lights. It can be a nightmare! Good luck.

u might have locked the steering wheel which wont let the ingnition turn.
