My 91 Chrysler New Yorker Salon is having headlight issues. When I pull the headlight knob, my headlights and doors do not open. If I pull the knob and pull the lever for high beams, the doors open with no headlights. If I pull and hold in the high beam lever, I get headlights only til I release the lever. In 2 of the times this happened, The lights finally came on about 15 minutes later. I don't know where to start looking. Thanks for any ideas. Tina.g
