interior lights 2002 T&C lxi
 

What runs the interior lights in my van? I just purchased it and found that I can manually turn on interior lights but opening the door or turning the dial won't turn them on. Also the dash light brightness doesn't change when I turn the dial. The door ajar indicator comes on when any of the doors are opened. Any help would be appreciated.:confused:
Thank you:)
