Open the driver-side lower dash panel to access the main electrical distribution unit; it is mounted above the footwell and protected by a snap-on plastic cover that can be removed without tools.
Use the printed reference chart on the inside of the cover to match slot numbers with systems such as lighting, audio, seat controls, and onboard electronics, allowing precise identification of each circuit.
If a component stops working, remove the protective link with the built-in puller and inspect it closely; a broken internal strip or darkened housing confirms failure and requires replacement with the same amperage value.
A second power distribution section is located under the hood near the battery; this unit handles high-load circuits including cooling fans and main supply lines, and should be checked if cabin circuits remain functional.
2010 Acura MDX Fuse Box Diagram Locations and Circuit Mapping Guide
Access the main cabin electrical panel under the driver-side dashboard; remove the lower cover to reveal a grid of numbered slots assigned to specific systems.
The layout separates circuits by function: lower positions typically control lighting and basic electronics, mid-range slots handle audio, climate control, and seat adjustment, while upper numbers connect to control modules and onboard systems.
Each slot is rated by amperage, commonly 7.5A, 10A, 15A, 20A, and 30A, with higher ratings supporting components like power seats or window motors; always match the rating exactly when replacing a blown element.
The engine compartment contains a second distribution center near the battery, where high-load circuits such as cooling fans, ABS, and charging systems are protected by larger capacity links.
Use the reference chart attached to the panel cover to match slot numbers with circuit functions, reducing time spent searching for the correct position during troubleshooting.
Test both contact points on each slot using a multimeter; voltage present on only one side indicates a failed link that must be replaced to restore operation.
Exact Fuse Box Locations in 2010 Acura MDX and Access Instructions
Open the driver-side lower dash panel and locate the main electrical block above the footwell; pull the plastic cover outward from the bottom edge to expose the slot array.
A secondary panel is installed under the hood near the battery; release the retaining clips on the lid and lift it upward to access high-current links connected to major systems such as cooling fans and braking electronics.
An additional small panel may be positioned on the passenger side near the kick panel; remove the trim carefully by pulling it straight out to reach auxiliary circuits tied to interior lighting and accessory controls.
