Headlights (appear to be low beam) remain ON despite headlight switch in OFF position. (Other positions work ,e.g., fog lights.) High beam indicator illuminated. Flicking high beam or trying to turn them off has no effect. Automatic shut-off occurs after 10 minutes or so. But open door or put key in ignition switch starts the cycle all over again. Suspect headlight switch OFF contact has failed. To check it I have to remove panel its mounted to. Am reluctant to force plastic panel. How do I remove it? Yes, I know that disconnecting battery shuts lights off but it starts all over again as soon as battery is reconnected.
