Find the fuse box and relay locations for the Chevrolet Tahoe/Suburban 2021-2024. Detailed diagrams to ensure smooth and reliable electrical system operation.
The Chevrolet Tahoe and Suburban 2021-2024 are full-size SUVs that embody strength, luxury, and versatility. The Tahoe offers seating for up to nine passengers, while the Suburban provides even more interior space and cargo capacity. Both models feature a bold design, powerful engine options, and advanced technology to meet the needs of families, adventurers, and professionals alike. With their robust towing capabilities and smooth driving dynamics, they remain popular for both urban and off-road use.
For efficient operation of the electrical systems in these vehicles, the fuse box and relay are integral. The fuse box in both the Tahoe and Suburban is located under the hood, usually near the driver’s side, with additional fuse panels found inside the cabin, near the dashboard or under the glove compartment. These components control crucial systems such as the lighting, air conditioning, and infotainment system. Relays are responsible for higher-power systems like the starter and fuel pump. Regular inspection and maintenance of the fuse box and relay are essential for ensuring uninterrupted performance of all vehicle systems.

WARNING
- Never replace a fuse with one that has a higher amperage rating.
- A fuse with a too-high amperage could damage the electrical part and cause a fire.
- On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
- If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
- Terminal and harness assignments for individual connectors will vary depending on vehicle equipment level, model, and market.

Instrument Panel Fuse Block:
The fuse block for the instrument panel can be located at the side of the instrument panel near the passenger’s seat. By pulling off the cover, you will have access to the fuse block. A fuse puller is stored on the right side of the instrument panel cap, which you can use for removing the fuses. Furthermore, the relays are situated at the back of the fuse block. Access to these relays can be gained by pressing the tabs and removing the fuse block altogether.
Engine Compartment Fuse Block:
The fuse block for the engine compartment is located in the engine bay, on the driver’s side of the car. To gain access to the fuse block, lift the cover.
Rear Compartment Fuse Block:
To access the rear compartment fuse block, move to the left side of the car’s compartment. There exists a panel in front of the fuse block; should you require access, gently pull the panel outward using the finger access slot found on the rear edge of the panel.
