In this article, you will find information about the fuses of the Cadillac XT6 (models 2020, 2021, 2022, 2023, and 2024), including diagrams of the fuse boxes, a list of fuses and relays, their designation, and the location of the fuse blocks within the vehicle.
Checking and Replacing Fuses in Cadillac XT6
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. To check a fuse, look at the band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a fuse of the identical size and rating.
Caution!
Do not exceed the specified amperage rating when replacing fuses and circuit breakers. Use of an oversized fuse or circuit breaker can result in a vehicle fire.
Location of Fuse Boxes
Engine Compartment Fuse Block: The underhood fuse block is in the engine compartment, on the driver side of the vehicle. To remove the fuse block cover, press the clips on the cover and lift it straight up. Do not pull the engine compartment fuse block lever, since it is intended only for service purposes. If pulled, vehicle malfunction may occur.
Instrument Panel Fuse Block: The instrument panel fuse block is in the center console between the driver and passenger seats. To access the fuses, open the fuse panel door, or remove the panel from the passenger side by pulling it out, or see your dealer.
Rear Compartment Fuse Block: The rear compartment fuse block is in the cargo area, on the driver side of the vehicle behind the lower trim panel. To access the fuses in the Rear Electrical Center, remove the center cargo bin, then small side bin. The label for this fuse block is in the spare tire area, on the foam under the cargo floor.
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.
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.
