Some Electrical Help Please...

Operation as follows.
Door open, headlight switch OFF, NO dome light operation.

Depress dome light switch with finger to simulate door closed, headlight switch still OFF, turn switch all the way counter clock wise, dome light comes on.

Turn switch one click clockwise to turn dome light off and it turns off. Remove finger from switch, still off. Turn headlights on, dome light comes on. Turns off when switch is depressed.
It sounds to me like the ground from the headlight switch is going to the The door switch ground when it should be just going to ground...
