Check the interior power distribution panel on the passenger side dashboard first, as most lighting, infotainment, and accessory issues originate there. Use a multimeter to verify voltage and continuity before removing any protective element.
This sedan uses multiple distribution units, including a cabin panel and an engine compartment module. The interior unit handles low-amperage circuits such as dashboard electronics and climate control, while the engine-side module supports higher load systems like cooling fans and ignition components. Each slot is labeled with a number and amperage rating, which must match the installed component.
Common faults include oxidized контакts, loose seating, and heat damage on frequently used circuits. Inspect terminals for discoloration, melting, or weak contact points, especially in power outlet and lighting circuits that operate regularly.
Access typically requires removing a plastic cover secured by clips. Once opened, compare the slot numbering with a verified layout reference to identify each circuit path and avoid disconnecting active control modules unintentionally.
2015 Malibu Fuse Diagram Layout and Circuit Identification

Match each numbered slot in the interior and engine compartment power panels with its assigned circuit using a verified layout reference, focusing first on systems that have stopped responding such as lighting, power outlets, or climate controls.
The cabin panel typically contains low to mid-amperage elements ranging from 5A to 25A, while the engine compartment unit handles higher loads such as cooling fans and control modules with ratings above 30A. Identify circuits by combining slot number, amperage rating, and wire color; thicker red cables indicate constant battery supply, while thinner wires carry switched current. Use a multimeter to confirm continuity across each protective element, since internal breaks are not always visible, and ensure each installed component matches the specified rating to prevent overheating and wiring damage.
Interior and Engine Bay Fuse Panel Locations in 2015 Malibu
Open the passenger-side dashboard end panel to access the interior power distribution unit, which is positioned behind a removable cover near the glove compartment.
Pull the cover outward to release the retaining clips; no tools are required. Inside, a compact panel with numbered slots controls cabin электроцепи such as lighting, infotainment, and climate systems.
The engine compartment distribution module is located near the battery and enclosed in a sealed housing. Press the side latches and lift the cover to expose high-amperage components and relays responsible for cooling fans, ignition systems, and control modules.
Check the under-hood unit first when multiple major systems fail simultaneously, as it handles higher electrical loads and shared power lines across several components.
After inspection, ensure all covers are securely reinstalled to protect контакts from moisture and maintain stable electrical connections.
