Fuses And Circuit Breakers - Cadillac CT4 2023 Owner's Manual

314 Vehicle Care
3. Use the fuse puller to remove the fuse
from the top or side, as shown above.
4. If the fuse must be replaced
immediately, borrow a replacement fuse
with the same amperage from the fuse
block. Choose a vehicle feature that is
not needed to safely operate the vehicle.
Repeat Steps 2-3.
5. Insert the replacement fuse into the
empty slot of the blown fuse.
At the next opportunity, see your dealer to
replace the blown fuse.
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.
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 windshield 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 windshield, 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 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.

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.
