1995 Chrysler LHS with electrical problems

I have a 1995 Chrysler LHS and my interior lights has problems. This is what it is doing first when I get out of car and shut door the lights will not turn off now if I get back in car and start my engine then shut door they will shut off then I have to turn engine off then remove key then get back out of car and shut door then they will shut off. Now I have already checked the switches on each door and they are good plus my message center shows all door are shut when they are shut and when I open one it shows they are open so I do not believe it has anything to do with door switches. Do you have any suggestions as to what my problem may be?
