2013 Cadillac CTS Fuse Replacement | Fuse Diagram and Relay Guide
In 2013, the Cadillac CTS Fuse Replacement is an important step to make sure the electrical system of the car works right. To keep the car running well, you need to understand the Fuse Diagram and Relay Guide. The main switch box under the hood is an important part of how the car works. If you know how to take it out and put it back in, you can fix problems like the engine not starting at random. To make sure the new front fuses and parts work right, you need to pay close attention to the details and follow the steps exactly as written. Relays, circuit breakers, and fuse blocks are all important parts of the electrical system that may need to be replaced to keep the Cadillac CTS working well.

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 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 you can.
To identify and check fuses, circuit breakers, and relays, see Engine Compartment Fuse Block (CTS-V Wagon) on page 10‑46 or Engine Compartment Fuse Block (CTS Coupe and Sedan) on page 10‑35 or Engine Compartment Fuse Block (CTS-V Coupe and Sedan) on page 10‑39 or Engine Compartment Fuse Block (CTS Wagon) on pages 10‑42 and Rear Compartment Fuse Block (CTS Wagon) on pages 10‑54 or Rear Compartment Fuse Block (CTS-V Wagon) on page 10‑56 or Rear Compartment Fuse Block (CTS Coupe and Sedan) on page 10‑49 or Rear Compartment Fuse Block (CTS-V Coupe and Sedan) on page 10‑52.
Engine Compartment Fuse Block (CTS Coupe and Sedan)
The underhood fuse block is on the left side of the engine compartment.
Lift the fuse block cover to access the fuses.
The vehicle may not be equipped with all of the fuses and relays shown.
Notice: Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component.
