Check the cover label inside the power distribution panel and match each slot number before removing any protective link. This crossover uses two main units: one in the engine compartment for high-load circuits and another inside the cabin for electronic systems.
The engine bay module contains larger current protectors rated 30A to 80A, supporting systems like cooling fan, ABS pump, and main power supply. Inside the vehicle, smaller blade-type elements rated 5A to 25A control infotainment, interior lighting, seat heaters, and control modules.
Use a multimeter in continuity mode to confirm whether a link has failed instead of relying on visual inspection. Hairline breaks are often hard to see, especially in low-amperage components, which leads to misdiagnosis.
Relays placed рядом with these panels handle switching for fuel delivery, starter operation, and climate control. Incorrect placement or failure can cause intermittent power loss, delayed engine start, or non-working accessories.

Match each slot number on the cover chart with the corresponding circuit before removing any protective element, since this model uses multiple panels with different layouts for engine systems and interior electronics. The engine compartment unit contains high-current links rated 30A to 80A for radiator fan, ABS, and power distribution, while the interior panel handles lower ratings such as 5A to 25A for infotainment, lighting, and control modules.
Relays placed рядом with these panels manage switching for starter motor, fuel pump, and climate system; incorrect positioning leads to no-start conditions or intermittent operation. Use a multimeter to verify continuity across each link and check relay terminals for proper voltage supply before replacing parts.
Exact fuse box locations in 2020 Kia Sorento under hood and cabin area
Open the hood and locate the main power distribution unit next to the battery on the driver side, covered by a rectangular plastic lid with locking tabs. This enclosure contains high-current protection links and switching components for engine-related systems.
Release the side clips carefully and lift the cover straight up to avoid breaking the hinges. Inside, you will see grouped cartridge-style inserts and relays arranged in rows, with identification markings printed on the underside of the lid.
Engine compartment unit position details
- Mounted near the battery for minimal voltage drop
- Close to the fender wall on the driver side
- Protected by a sealed plastic housing against moisture
- Includes high-amperage circuits for cooling, ABS, and ignition
Move inside the vehicle and check the passenger side dashboard area, where the secondary panel is installed behind a removable trim cover. Access requires opening the glove compartment or removing a small side panel depending on trim level.
Interior panel access points
- Open passenger door fully
- Locate side trim near dashboard edge
- Pull cover gently to expose the panel
- Use a flashlight to read slot markings clearly
This interior unit contains low-amperage blade-style inserts for electronics such as infotainment, interior lighting, and driver assistance modules. The layout is compact, so careful handling prevents damage to surrounding wiring.
Keep both covers secured after inspection, since loose panels allow dust and moisture to reach contacts, which can lead to corrosion and unstable electrical connections over time.
