Lincoln Navigator headlights dim and interior lights malfunctioning with intermittent high beam issues on Lincoln Navigator

Some Lincoln Navigator owners report experiencing issues with dimming headlights, malfunctioning interior lights, and intermittent high beam problems. These concerns may stem from problems with the main headlight switch, which can cause both dimming and high beam issues if not properly addressed. Additionally, some owners have noted that their interior lights remain on even when all doors are closed, suggesting potential faults in the lighting system, particularly in the wiring located in the rubber boot between the body and the liftgate. Furthermore, intermittent high beam issues might indicate underlying electrical component or wiring problems. It is advisable for owners to inspect these areas and consult a professional for a thorough diagnosis and repair if the problems persist.
