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-coloured 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, Instrument Panel Fuse Block, and Rear Compartment Fuse Block.

Engine Compartment Fuse Block
To remove the fuse block cover, press the clips on the cover and lift it’s straight up.

Caution
Spilling liquid on any electrical component of the vehicle may damage it. Always keep the covers on any electrical component.

How to Replace 2014 Cadillac SRX fuse

Even though changing a fuse is pretty easy, it’s important to follow safety rules to keep yourself and any electrical parts from getting hurt. This is outline of how to change a fuse:

1. Figure out which fuse is broken
   • The fuse box for your home is generally in the basement, garage, utility room, or close to the electrical panel.
   • You can get to the fuses by taking off the lid of most fuse boxes. Find the spark that went out. When fuses are blown, the wires inside are often broken and the fuse itself looks damaged.
2. Turn off the power:
   • It’s important to turn off the power to the circuit where the fuse is, before changing it. Most of the time, you can do this by turning off the main circuit breaker in your electricity panel.
3. Take out the blown fuse:
   • Carefully grasp the blown fuse and pull it straight out of its hole with a fuse puller or a pair of insulated pliers. Not having a fuse puller? You can use shielded tools instead, but make sure the power is off to avoid getting shocked.
4. Choose a new fuse:
   • Look at the metal band of the blown fuse to see what the amperage value is written on it. To make sure you’re safe, you must change it with a fuse that can handle the same amount of current.
   • You need to make sure you have the right type and size of fuse. Fuses come in different sizes and types, so make sure the one you choose fits the socket correctly.
5. Put in the new fuse:
   • Make sure the new fuse fits firmly into the empty socket before plugging it in.
   • Do not touch the metal parts of the switch with your fingers. If you do, you could get dirt on them and make them not work properly.
6. Turn the power back on:
   • If you took the cover off the fuse box earlier, put it back on after making sure the new fuse is in place.
   • Flip the main circuit breaker or the individual breaker for the circuit you’re working on to turn the power back on.
7. Test the circuit
   • Once the power is back on, test the circuit to make sure everything is working right. 

When working with electrical parts, safety should always come first. If you’re not sure how to change a fuse or feel comfortable doing it yourself, you should get help from a trained electrician.
