In this article, you will find information about the fuses of the Cadillac XT4 (models 2019, 2020, 2021, 2022, and 2023), 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 XT4
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 silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Replace a bad fuse with a new one of the identical size and rating.
Caution!
- Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component.
- 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 on the driver side of the instrument panel, between the steering wheel and the door. To access the fuses, remove the panel, starting at the top. Once clips are disengaged, the tabs along the bottom of the door can be disengaged from the instrument panel to remove the door.
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.
