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.
2012 Cadillac SRX 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 you can. To identify and check fuses, circuit breakers, and relays, see Engine Compartment Fuse Block on pages 10‑42 and Rear Compartment Fuse Block on pages 10‑46.
Engine Compartment Fuse Block
To remove the fuse block cover, press the 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.

How to Replace Fuse in 2012 Cadillac SRX
Materials Needed:
- Replacement fuse(s) of the appropriate amperage rating: It’s essential to have replacement fuses on hand that match the amperage rating of the blown fuse you’re replacing.
- Fuse puller or a pair of needle-nose pliers: A fuse puller is a handy tool designed specifically for removing fuses from the fuse box safely. If you don’t have a fuse puller, a pair of needle-nose pliers can also be used, but be careful not to damage the fuse or the fuse box when removing and inserting fuses.
Instructions:
- Locate the Fuse Box: The fuse box in the 2012 Cadillac SRX is typically located in one of two places: either under the dashboard on the driver’s side or in the engine compartment near the battery.
- Identify the Blown Fuse: Before removing any fuses, it’s crucial to identify the one that needs replacing. Look for fuses with visible signs of damage, such as a burnt or broken metal strip.
- Turn Off the Ignition: To avoid the risk of electrical shock or damage, turn off the ignition and remove the key from the ignition switch before proceeding.
- Use the Fuse Puller: If your vehicle is equipped with a fuse puller, use it to grasp and gently pull out the blown fuse. If a fuse puller is not available, a pair of needle-nose pliers can be used instead. Be sure to grip the fuse firmly but not too forcefully to avoid damaging it or the fuse box.
- Insert the Replacement Fuse: Take a replacement fuse of the same amperage rating as the one you removed. Carefully insert it into the empty fuse slot, making sure it fits snugly and securely.
- Test the Circuit: Once the replacement fuse is installed, turn the ignition back on and test the circuit associated with the fuse to ensure that the problem has been resolved. If the circuit is still not functioning properly, double-check the fuse and its installation.
- Replace Fuse Box Cover: Once you’ve confirmed that the replacement fuse has resolved the issue, replace the fuse box cover and ensure it is securely fastened to prevent dust and moisture from entering the fuse box.
Tips:
- Always use replacement fuses of the same amperage rating as the original ones to avoid causing electrical damage to your vehicle.
- Regularly inspect your vehicle’s fuses for signs of wear or damage, especially if you experience recurring electrical problems.
- Consider keeping a spare fuse kit in your vehicle for emergencies, especially during long trips or in remote areas where access to replacement fuses may be limited.
