6-56 Headlamp Wiring
The headlamp wiring has an individual fuse which is
powered by a MaxiFuse
. An electrical overload will
cause the lamps to go on and off, or in some cases to
remain off. If this happens, have the headlamp wiring
checked right away.
Windshield Wiper Fuses
The windshield wiper motor is powered by a
MaxiFuse
. If the motor overheats due to heavy snow,
etc., the wipers will stop until the motor cools. If the
overload is caused by some electrical problem, be sure
to have it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load is too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is fixed or goes away.
MaxiFuse
/Relay Center
The MaxiFuses and relays are located next to the engine
compartment fuse block on the driver's side of the
engine. To access the compartment fuse block, remove
the shroud cover. If a MaxiFuse should blow, have your
vehicle serviced by your dealer immediately.
