Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
Bulb

electrical system overload.

Number
When the current electrical load is
921
too heavy, the circuit breaker opens
and closes, protecting the circuit
168
until the current load returns to
normal or the problem is fixed. This
3157K LL
greatly reduces the chance of circuit
overload and fire caused by
electrical problems.
GM P/N
Fuses and circuit breakers protect
25874489
power devices in the vehicle.
Replace a bad fuse with a new one
of the identical size and rating.
If there is a problem on the road and
a fuse needs to be replaced, the
same amperage fuse can be
borrowed. Choose some feature of
the vehicle that is not needed to use
and replace it as soon as possible.

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.

Windshield Wipers

If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.
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 windshield before using the
windshield wipers.
If the overload is caused by an
electrical problem and not snow or
ice, be sure to get it fixed.
