One problem related to headlight switch has been reported for the 1998 Mercury Grand Marquis. The most recently reported issues are listed below.
Light switch fails while lights are on high beam for one to two hours. Has happened four times while driving at 70 mpr on interstate 95. All interior and exterior lights blink off, then back on, then off several times before pulling to side of road. . . Has not happened while using low beams. Strikes fear in me and family each time it happens. . . I understand it common to my yr and make. . . What to do??.
