2023 Chevrolet Tahoe Fuses And Fuse Box | How to Fix Blown Fuse
Like every other car, the 2023 Chevrolet Tahoe has a fuse box to guard against overloads and short circuits on its electrical systems. A blown fuse may be the cause of a specific electrical component in your Tahoe ceasing to function. Because they are made to “blow” or break when they sense an electrical overload, fuses shield the linked systems from harm. Any owner of a car can do the comparatively simple task of fixing a blown fuse in their Tahoe. Finding the fuse box, identifying the blown fuse, and replacing it with a new one with the same amperage rating are the steps involved in doing this. To determine the precise position of the fuse box and a description of the functions that each fuse regulates, it is imperative that you refer to the owner’s manual for your car. You can make sure that the electrical systems in your 2023 Chevrolet Tahoe are operating smoothly and effectively by following these easy steps. Always remember to operate safely and cautiously when handling the electrical parts of your car.
Headlamp Aiming
Front Headlamp Aiming
The headlamp aim has been preset and should need no further adjustment. If the vehicle is damaged in a crash, the headlamp aim may be affected. If an adjustment to the headlamps is necessary, see your dealer.
Bulb Replacement
For the proper type of replacement bulbs, or any bulb changing procedure not listed in this section, contact your dealer.
Caution
Do not replace incandescent bulbs with aftermarket LED replacement bulbs. This can cause damage to the vehicle electrical system.
LED Lighting
This vehicle has several LED lamps. For replacement of any LED lighting assembly, contact your dealer.
Taillamps, Turn Signal, Stop lamps, and Back-Up Lamps
Base Level Taillamp Assembly
-
Stop Lamp
-
Turn Signal Lamp
-
Back-Up Lamp
It is recommended to replace the grommets when replacing a bulb. See your dealer.
To replace one of these bulbs:
- Open the liftgate.
- Remove the middle trim piece by pulling towards the centre of the vehicle to disengage the clips.
- Remove the lower taillamp closeout cover from the taillamp assembly by pulling rearward from the top and bottom to disengage the clips.
- Remove the two rear lamp assembly screws.
-
Pull the rear lamp assembly rearward to remove it from the vehicle.
-
Turn the bulb socket counterclockwise.
-
Pull the bulb straight out from the socket.
-
Replace the bulb and reverse Steps 1–6 to reinstall.
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 the wires that provide the power to the devices in your 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 vehicle.
- Locate the fuse puller on the instrument panel end cap. See the Instrument Panel 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, spare fuses are also provided on the instrument panel end cap or 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 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.
Danger
Fuses and circuit breakers are marked with their ampere rating. Do not exceed the specified amperage rating when replacing fuses and circuit breakers. 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.
Engine Compartment Fuse Block
The engine compartment fuse block is in the engine compartment, on the driver side of the vehicle.
Lift the cover to access the fuse block.
Caution
Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component.

FAQs
The fuse box in a 2023 Chevrolet Tahoe is typically located in the engine compartment or the interior cabin, depending on the specific model and
trim level.
There may be multiple fuse boxes in the 2023 Chevrolet Tahoe, including one in the engine compartment and one in the interior cabin.
Fuses in the Tahoe protect electrical components by breaking the circuit when an electrical overload or short circuit occurs, preventing damage.
A blown fuse can often be identified by a visibly broken or melted filament inside the fuse, or by using a multimeter to check for continuity.
You may need a fuse puller, a flashlight, and replacement fuses of the same amperage rating.
Replacement fuses are typically available at auto parts stores or can be purchased online.
Fuses come in various amperage ratings, which indicate the amount of current they can handle before breaking the circuit. It’s essential to replace a blown fuse with one of the same amperage rating.
Insert the fuse puller over the blown fuse, squeeze the handles together, and gently pull the fuse out of its socket.
It’s not recommended to use a higher amperage fuse as it can lead to electrical system damage or fires. Always replace with the same amperage fuse.
If a replacement fuse continues to blow, it indicates an underlying electrical problem that should be diagnosed and repaired by a professional mechanic.
Once you’ve replaced the blown fuse with a new one, the circuit should automatically reset, restoring power to the affected electrical component.
It’s safer to disconnect the vehicle’s battery when working with fuses to prevent accidental electrical shorts.
Yes, you can often find a fuse diagram in your vehicle’s owner’s manual or by searching online for a Tahoe fuse box diagram specific to your model year.
Common electrical issues can vary, but blown fuses are relatively common and can affect various electrical components.
To prevent blown fuses, avoid overloading electrical circuits, ensure all accessories are properly connected, and periodically inspect your vehicle’s electrical systems.
