Electrical System
Electrical System Overload
The vehicle has fuses and circuit breakers to protect against an electrical system overload.
When the current electrical load is too heavy, the circuit breaker opens and closes, protecting the circuit until the current load returns to normal or the problem is fixed. This greatly reduces the chance of circuit overload and fire caused by electrical problems.
Fuses and circuit breakers protect 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. 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.
To check a fuse, look at the silver-colored 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,

FAQs
In the passenger compartment of the 2017 Cadillac CT6, the fuse box is usually either beneath the steering column or on the dashboard on the driver’s side.
Check the fuse visually. A burned or shattered metal strip within the fuse indicates that it has blown.
To find out the right fuse size and amperage rating for each circuit in your 2017 Cadillac CT6, see the owner’s handbook or the fuse box lid.
To securely remove the blown fuse, you might require a fuse puller tool or a pair of needle-nose pliers.
Before attempting to repair the blown fuse, buy replacement fuses from an auto parts store with the same amperage rating.
Fuses usually blow because of an electrical overload or short circuit. Look for any malfunctioning parts or circuitry that might be the source of the problem.
No, it isn’t advised. Fusing something with a higher amp rating than what is recommended can harm the electrical system or possibly start a fire.
Carefully pry the fuse out of its socket with a pair of needle-nose pliers or a fuse puller tool. Don’t use too much force to stop damage.
This can point to a more serious underlying electrical problem. It is recommended that the car be inspected by a licensed mechanic.
To avoid electrical shocks or harm to the electrical system, make sure the vehicle’s ignition is off before changing fuses.
Regularly checking the fuses is a smart practice, particularly if you’ve just replaced a defective fuse or are having electrical problems.
