In this article, you will find information about the fuses of the Cadillac XTS (models 2013, 2014, 2015, 2016, and 2017), 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 XTS
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.
Location of Fuse Boxes
Engine Compartment Fuse Block: To remove the fuse block cover, squeeze the three retaining clips on the cover and lift it straight up.
Instrument Panel Fuse Block: The instrument panel fuse block is in the instrument panel, on the driver side of the vehicle. To access the fuses, open the fuse panel door by pulling down at the top. Press in on the sides of the door to release it from the instrument panel. Pull the door toward you to release it from the hinge.
Rear Compartment Fuse Block: The rear compartment fuse block is on the left side of the trunk behind a cover.
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. If the overload is caused by an electrical problem and not snow or ice, be sure to get it fixed.
