Cadillac CTS (2012-2014)

Checking and Replacing Fuses in Cadillac CTS Coupe and Sedan

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:
The underhood fuse block is located on the left side of the engine compartment. Lift the fuse block cover to access the fuses.

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.
