Locate both electrical panels before checking any power issue–one is positioned in the engine compartment near the battery, while the second is installed inside the cabin under the dashboard on the driver side. Each panel distributes current to specific systems such as lighting, ignition, and onboard electronics.
Use the printed layout on the cover to match slot numbers with components. Lower-rated inserts like 10A or 15A typically protect sensors, audio system, and control modules, while higher ratings such as 20A to 40A supply motors, cooling fans, and power-operated features.
Inspect each insert visually and verify with a multimeter if needed. A broken internal strip indicates failure, but continuity testing confirms it. Always replace with the same amperage value to prevent overheating or wiring damage.
Check relay units located in the same panel if a system stops working without a damaged insert, since these components manage switching for high-load circuits. Swapping with an identical relay helps identify faults quickly.

Check the cabin electrical panel under the driver side dashboard first, where low-amperage slots handle lighting, radio, and accessory circuits; use the lid label to match each slot with its assigned system before replacing any blown link.
The engine bay power distribution unit sits near the battery and contains high-current protection elements for cooling fans, ABS, and charging system; inspect larger rated inserts (30A–60A) and confirm continuity with a multimeter rather than visual inspection alone.
Inside the passenger compartment, the layout is arranged in rows with clear numbering; match each position to systems such as power windows, interior lamps, and ECU feed lines to isolate faults quickly.
Under the hood, relay modules are integrated into the same housing as the main protection panel; identify relay positions controlling ignition, fuel pump, and radiator fans, as faults here may mimic wiring issues.
Use amperage markings stamped on each component to avoid installing a higher-rated replacement, which may damage wiring; typical ratings range from 10A for electronics to 50A for major systems.
Exact locations of interior and engine compartment fuse panels in 2007 Matrix
Locate the cabin panel beneath the dashboard on the driver side, directly above the footwell; remove the small plastic cover by pulling it toward you to access the low-current protection slots tied to interior electronics.
The inner compartment layout is positioned slightly left of the steering column, close to the kick panel, making it reachable without tools; a flashlight helps identify slot numbering and printed labels on the rear side of the cover.
Typical circuits in this area include:
- audio system and clock memory
- power mirrors and windows
- interior lighting and accessory ports
- engine control module feed lines
Move to the engine compartment and find the main power distribution unit near the battery on the driver side; it is enclosed in a rectangular black housing with a snap-on lid that seals tightly against moisture.
Release the cover clips by pressing inward, then lift upward; inside, you will see larger amperage elements and relay blocks arranged in a grid pattern for quick identification.
Key components in this area include:
- cooling fan protection rated around 30A to 40A
- anti-lock braking system circuits
- charging system link connected to the alternator
- ignition and starter relay positions
Check the underside of the lid for a printed layout that maps each slot and relay; align the orientation of the cover with the installed components to avoid confusion while tracing electrical paths.
