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
The wiring circuits in the vehicle are protected from short circuits by
fuses. This greatly reduces the chance of fires caused by electrical problems.
Look at the silver-coloured band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you 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.
Engine Compartment Fuse Block
The engine compartment fuse block is in the engine compartment, on the driver’s side of the vehicle.
Lift the cover to access the fuse block.
Caution
Spilling liquid on any electrical component of the vehicle may damage it. Always keep the covers on any electrical component.
A fuse puller is available in the left instrument panel fuse block.

How to Replace Fuse
The process of changing the fuses in a 2015 Cadillac Escalade is not too complicated. Here’s a basic guide on changing fuses:
- Find the Fuse Box:
- The engine compartment or the interior of the 2015 Cadillac Escalade is typically where you can find the fuse box. Under the hood, next to the battery, or inside the kick panel on the driver’s or passenger’s side are typical places.
- Turn Off the Ignition:
- Turn off the ignition and any other electrical devices connected to the fuse you are changing before you begin.
- Remove the Fuse:
- Grab the fuse and pull it out using a fuse puller tool or a pair of needle-nose pliers. Make sure you have a firm grip on the fuse and pull it straight out.
- Inspect the Fuse:
- Verify the integrity of the metal strip inside the fuse. If the metal strip breaks, the fuse is probably blown and has to be changed.
- Choose a New Fuse:
- Make sure the replacement fuse has the same amp rating as the one you took out. Usually, the fuse’s top has printing that indicates the amp rating. It is essential to use a fuse with the right rating to avoid electrical problems and vehicle damage.
- Place the New Fuse Here
- Make sure the new fuse is firmly seated by pushing it into the vacant slot. It should be a tight fit.
- Test the Component:
- After turning on the ignition, make sure the system or component connected to the replaced fuse is operating properly by testing it.
- Replace the Fuse Box Cover:
- If a fuse box cover needs to be taken off, firmly replace it.
