Fuse Diagram and Relay: 2013 Cadillac XTS Fuses Guide
The 2013 Cadillac XTS has a complex fuse diagram and switch system that is very important for controlling the electrical parts of the car. In the event of an electrical overload or fault, this system will protect the car’s connections from damage. To fix electrical problems in the car, you need to know how to read the switch diagram. As safety measures, fuses break the connection when there is too much current flow, keeping the parts from getting damaged. On the other hand, relays are electrically managed switches that let a low-power signal run a high-power circuit. These parts of the 2013 Cadillac XTS work together to make sure that different systems, like the windows, lights, and more, work smoothly. To make sure the car’s electrical features work perfectly, you need to keep it in good shape and know how the fuse diagram and relay system work. The more you know about these parts, the easier it will be to find and fix electricity problems.

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 features of the vehicle that are not needed to use and replace them 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 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. 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, see Engine Compartment Fuse Block on pages 10‑26, Instrument Panel Fuse Block on page 10‑30, and Rear Compartment Fuse Block on page 10‑32.
Engine Compartment Fuse Block
To remove the fuse block cover, squeeze the three retaining clips on the cover and lift it straight up. Notice: Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component.
