One problem related to exterior lighting has been reported for the 1998 Lincoln Navigator. The most recently reported issues are listed below.
Started with the light in vechical staying on for hours at a time causing a loud noise under hood. While driving and picking up my girlfriend, we were scared by the sudden acceleration of my vechical. We hit another car causing our heads to hit the dash board. The car wouldn't stop so after we hit a car while on breaks, I through car in park and that just made car engine roar even louder causing engine to go into danger mood. Turned car off and started back up it was still roaring but then calm down to normal.
