272 VEHICLE CARE
Headlamp Wiring
An electrical overload may cause the
lamps to go on and off, or in some
cases to remain off. Have the
headlamp wiring checked right away if
the lamps go on and off or remain off.
Windscreen Wipers
If the wiper motor overheats due to
heavy snow or ice, the windscreen
wipers will stop. Wiper function is
available immediately after the wiper
switch is set to off, and back to on.
To protect the wiper motor from
overheating, the wipers may slow
down when the windscreen is dry for
a long period of time. If a period of
dry operation, or little moisture,
exceeds 10 minutes, the wipers may
switch to intermittent operation, and
remain there. When moisture is again
detected on the windscreen, wiper
operation will return to the operator
selected speed.
Although the circuit is protected from
electrical overload, overload due to
heavy snow or ice may cause wiper
linkage damage. Always clear ice and
heavy snow from the windscreen
before using the windscreen wipers.
If the overload is caused by an
electrical problem and not snow or
ice, be sure to get it fixed.

Fuses and Circuit Breakers

The wiring circuits in the vehicle are
protected from short circuits by a
combination of fuses and circuit
breakers. This greatly reduces the
chance of damage caused by electrical
problems.
To check a fuse, look at the
silver-coloured band inside the fuse.
If the band is broken or melted,
replace the fuse. Be sure to replace a
bad fuse with a new one of the
identical size and rating.
Fuses of the same amperage can be
temporarily borrowed from another
fuse location, if a fuse goes out.
Replace the fuse as soon as possible.
To identify and check fuses, circuit
breakers, and relays, see Engine
Compartment Fuse Block 0 272,
Instrument Panel Fuse Block 0 275, and
Rear Compartment Fuse Block 0 278.

Engine Compartment Fuse

Block

The underbonnet fuse block is on the
passenger side of the engine
