1996 Ford Windstar

Electrical problem
1996 Ford Windstar 6 cyl Automatic 200, 00 miles

I would like to know if you can help me figure out my van. The interior lights will not go off even when all doors are closed. It also only locks when it wants to such as when you put it in park instead of when you put it in gear like it is supposed to. That is if it even locks at all. The lights will go off eventually once you start driving but if you are not driving they do not wanna turn off. My door open light stays on most of the time also and we have checked all door latches.
