Why won't my headlight doors open but my running/parking lights still come on?

What is your question?

I have a 93 Chrysler Fifth Ave New Yorker. When I pull the headlight knob out the headlight doors don't open at all but the running lights still come on. I can push on top of the covers and they flip so I don't think they are stuck closed. The headlights aren't on behind the doors either when I pull the knob out. Any idea of what this could be and what I need to do?
