If fuses burn out
Burned-out or“blown-out”fuses or circuit breaker tripping (if equipped)
usually indicate an electrical short circuit, although a fuse may
occasionally fail from vibration. Insert a second fuse or reset the breaker
(if equipped). If this fuse immediately burns out or the breaker (if
equipped) trips and you cannot locate the fuse, return your vehicle to
your dealer for a circuit check.
If lamp bulbs burn out
Repeated lamp burn-out usually indicates a loose connection, either at
the lamp socket, the system ground or a malfunctioning voltage
regulator. If examination does not indicate the cause of the trouble,
return your vehicle to your dealer for inspection.
If headlamps flash on and off
If headlamps flash on and off at regular intervals, the system circuit
breaker (if equipped) is operating, indicating a short circuit or overload.
Take your vehicle to your dealer for a circuit check.
