Find fuse box and relay locations for the 2021-2024 Cadillac Escalade with detailed diagrams. Ensure reliable performance of critical electrical systems.
The 2021-2024 Cadillac Escalade (T1XL) embodies luxury in a full-size SUV, featuring a bold exterior and a spacious, upscale interior. Known for its iconic design, the Escalade comes in both standard and extended ESV body styles, providing ample space for passengers and cargo. With cutting-edge technology, including advanced driver-assistance systems and a premium infotainment setup, the Escalade delivers a high-end experience.
To power its numerous electronic features, the Escalade relies on a well-organized electrical system, including multiple fuse boxes and relays. The main fuse box is located in the engine compartment, while additional fuse boxes can be found under the dash and in the cargo area. These fuse boxes protect circuits for essential systems like lighting, climate control, and driver-assistance features. Relays, responsible for controlling high-power components such as the fuel pump and cooling fans, are housed near the fuse boxes. Regular inspection of these components ensures the Escalade’s technology functions reliably.

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.

Location of Fuse Boxes
Engine Compartment Fuse Block:
The engine compartment fuse block is in the engine compartment, on the passenger side of the vehicle. Lift the cover to access the fuse block.
Instrument Panel Fuse Block:
The right instrument panel fuse block access door is on the passenger side edge of the instrument panel. Pull off the cover to access the fuse block. A fuse puller is available on the right instrument panel end cap. There are relays on the back of the fuse block. To access, press the tabs and remove the fuse block.
Rear Compartment Fuse Block:
The rear compartment fuse block is behind the access panel on the left side of the compartment. Pull the panel out by grabbing the finger access slot at the rear edge.
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.
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.
