Locate the power distribution panel under the hood near the battery and inside the cabin on the driver’s side to quickly identify protected circuits and prevent electrical faults. These panels group safety links by system: lighting, infotainment, drivetrain controls, and auxiliary modules. Each slot corresponds to a rated current value, typically ranging from 5A for sensors to 40A+ for high-load components like cooling fans.
Under-hood configuration includes high-capacity links responsible for engine control module supply, ABS system, and radiator fan relays. Access requires releasing a plastic cover with clips; inside, markings indicate circuit abbreviations such as ECM, HVAC, and IGN. Cross-check amperage before replacement to avoid overheating or module failure.
Interior panel handles lower-current electronics: dashboard cluster, USB ports, seat adjustment motors, and airbag monitoring circuits. It is positioned behind a trim panel on the side of the dashboard. Use a puller tool stored in the panel itself to remove elements without damaging контакты.
Color coding and numbering follow a standardized scheme: yellow (20A), blue (15A), red (10A), and brown (7.5A). Matching these correctly ensures circuit stability. If a component stops working, inspect the corresponding slot by referencing the legend printed on the panel cover–this reduces diagnostic time significantly.
Practical tip: always disconnect the negative battery terminal before interacting with high-current sections. This prevents accidental short circuits and protects sensitive onboard electronics such as control modules and sensor arrays.

Check the power distribution panel under the hood first for high-load circuits like cooling fans, ABS, and ignition relays; use a multimeter set to continuity mode and verify each link against the legend printed on the cover, matching amperage ratings (10A, 15A, 20A, 30A, 40A) exactly–installing a higher rating risks wiring damage, while a lower one leads to repeated shutdowns. Inside the cabin, the secondary panel near the dashboard side trim handles lighting, infotainment, seat controls, and accessory sockets; remove trim carefully with a plastic tool to avoid clips breaking, and always disconnect the battery before replacing any blown element tied to sensitive electronics such as the BCM or radio unit.
For quick troubleshooting, map symptoms to circuits: no crank often points to starter relay or ignition circuit, dead infotainment suggests a blown low-amperage link in the interior panel, and non-working power seats usually trace back to a 25–30A slot in the cabin unit; use a test light to confirm voltage presence on both terminals of each slot, not just visual inspection, since hairline breaks are common. Label each position after verification with a fine marker on the cover to speed up future diagnostics, and keep spare links of the exact same rating in the glove compartment to avoid roadside delays.
Exact Locations of Interior and Engine Compartment Fuse Boxes in 2020 Cadillac Escalade
Open the driver’s door and inspect the left side of the dashboard: a removable trim panel hides the interior power distribution unit. Use a plastic pry tool to avoid scratching the surface, then pull the cover straight out. Inside, circuits for lighting, infotainment, and seat controls are grouped with clear numbering. For quick identification, match the numbering to the legend printed on the reverse side of the panel cover.
Cabin Panel Position Details
The interior unit is mounted vertically near the steering column, slightly below the air vent. Access requires no tools beyond gentle leverage. Key positioning notes:
- Located behind a snap-in dashboard cover facing the driver’s door
- Positioned above the footwell, left of the steering wheel
- Aligned with the instrument panel edge for direct reach
- Protected by a molded plastic shield with retention clips
Engine Bay Power Center
Lift the hood and move toward the front-right section of the engine compartment. The main electrical center sits adjacent to the battery, enclosed in a sealed black housing with a locking lid. Press the tabs on both sides to release the cover, then lift upward. Inside are high-amperage links for systems like cooling fans, ABS, and ignition. Layout is divided into rows, each marked with embossed labels. Keep moisture out by ensuring the lid snaps tightly after inspection. For orientation:
- Front-right corner relative to the engine
- Next to the battery casing and wiring harness junction
- Covered by a weather-sealed rectangular enclosure
- Accessible without removing surrounding components
