Display Goes to Minimum Brightness With Headlights On

Check to see if instrument panel illumination is adjustable with headlight switch rheostat. If adjustable, replace Navigator. If not, check fuses No. 12 and No. 5 (Daytona & LeBaron Convertible/Coupe) or No. 14 and No. 5 (Lancer & LeBaron GTS). If fuses are good, check headlight switch.
