Electrical System
High Voltage Devices and Wiring
Warning
Exposure to high voltage can cause shock, burns, and even death. The high-voltage components in the vehicle can only be serviced by technicians with special training.
High-voltage components are identified by labels. Do not remove, open, take apart, or modify these components. High voltage cable or wiring has orange covering or labels. Do not probe, tamper with, cut, or modify high-voltage cables or wiring.
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.
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.
To check a fuse, look at the band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a fuse of identical size and rating.
Replacing a Blown Fuse
- Turn off the ignition.
- Locate the fuse puller in the engine compartment fuse block.
- Use the fuse puller to remove the fuse from the top or side, as shown above.
- If the fuse must be replaced immediately, borrow a replacement fuse with the same amperage from the fuse block. Choose a vehicle feature that is not needed to safely operate the vehicle. Repeat Steps 2-3.
- Insert the replacement fuse into the empty slot of the blown fuse.
At the next opportunity, see your dealer to replace the blown fuse.
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. The wiper function is available immediately after the wiper switch is set to off, and back to on. To protect the wiper motor from overheating, the wipers may slow down when the windshield is dry for a long period. If a period of dry operation, or little moisture, exceeds 10 minutes, the wipers may switch to intermittent operation, and remain there. When moisture is again detected on the windshield, wiper operation will return to the operator-selected speed.
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.
Danger
Fuses and circuit breakers are marked with their ampere rating. Do not exceed the specified amperage rating when replacing fuses and circuit breakers. The use of an oversized fuse or circuit breaker can result in a vehicle fire. You and others could be seriously injured or killed.
Warning
Installation or use of fuses that do not meet GM’s original fuse specifications is dangerous. The fuses could fail, and result in a fire. You or others could be injured or killed, and the vehicle could be damaged.
The fuses and circuit breakers protect the electrical system from short circuits, greatly reducing the chance of electrical damage or fire.

Here’s how to locate and replace a blown fuse in your 2026 Cadillac VISTIQ:
Materials:
- The new fuse of the correct amperage.
- Fuse puller or needle-nose pliers.
Step-by-Step Fuse Replacement Guide
- Identify the right fuse box
-
Engine bay (power distribution center – PDC) under the hood
-
Instrument panel (behind passenger‑side glovebox)
-
Luggage compartment, driver‑side
-
- Turn off the vehicle
-
Shift to P (Park), exit the vehicle, and ensure everything is powered down.
-
Let high-voltage systems fully power down before proceeding
-
- Access the fuse box
-
Under-hood: remove the cover from the PDC.
-
Instrument panel: open glovebox, detach its stops, then pull out the cover.
-
Cargo area: pop off the side cover.
-
- Check the fuse diagram
-
The fuse box cover contains a printed diagram.
-
For internal box, fuses are labeled like “APO” (power outlets), “USB”, etc.
-
Identify the faulty fuse by function (e.g., horn, USB).
-
- Remove the blown fuse
-
Use the plastic fuse puller (usually clipped inside the box) or needle-nose pliers.
-
A blown fuse has a broken metal strip or discoloration.
-
- Install a new fuse
-
Insert a replacement fuse of identical amp rating (e.g., 10 A).
-
Press straight in – should fit snugly.
-
- Test before reassembly
- Power on the vehicle and verify the device (horn, lights, outlets) works correctly.
- Replace the cover
- Snap the fuse box cover back securely after testing.
Tips for a smooth process
-
Always replace a blown fuse with one that has the exact amperage.
-
Keep a few spare fuses (commonly 10 A, 15 A, 20 A) in your glove box for quick fixes.
