I was curious if all the interior lights be turned off when you have the doors open?

My PT Cruiser has a dimmer switch that you can turn all the way down and the all the interior lights(dome, doors) are off when the door is open. This is handy when I'm cleaning the car and don't want to run the battery down with the doors open.

I see an"OFF" on the light control arm on the steering column but the door lights are still on when the door is opened.

Any ideas?
