Where is the fuse box on an Acura MDX?
The Acura MDX typically uses two main fuse boxes: one under the hood in the engine compartment and one inside the cabin under the driver's side dash. The exact layout can vary by model year, so check your owner's manual for year-specific diagrams and fuse ratings.
Two primary fuse box locations and how to access them
Here’s a practical guide to locating and using each fuse box. Each box is clearly labeled with a diagram showing fuse designations and amperage ratings.
Under-hood fuse/relay box (engine compartment)
The engine compartment houses the main fuse/relay box in a black plastic housing with a removable lid. The lid typically features a diagram that indicates which fuse protects each system. Access involves lifting the latch or clips to remove the cover, then inspecting or replacing fuses as needed.
Before the list, note: This box protects critical systems such as engine control, powertrain, and primary electrical components. Always replace a blown fuse with one of the same amperage rating and reseal the box to protect against moisture.
- Locate the engine compartment fuse box in the engine bay and lift the cover to remove it.
- Refer to the fuse/relay diagram on the inside of the lid to identify the circuit you’re inspecting.
- Use the included fuse puller or a non-conductive tool to remove a blown fuse and replace it with a fuse of the same amperage.
- Reinstall the lid securely to preserve protection against dirt and moisture.
In case of persistent electrical issues after replacing a fuse, consult the owner's manual or a dealership for a thorough diagnostic.
Interior cabin fuse box (driver’s side dash)
The interior cabin fuse box is located under the driver's side dash, typically near the left footwell. It is accessed by removing a small panel; the cover on the panel includes a diagram listing the fuses and their corresponding circuits.
Before the list, another note: This box covers fuses for interior electronics, lighting, windows, infotainment, and other cabin systems. Handle the panel gently to avoid damaging the clips or wires, and always match fuse amperage when replacing.
- Open the access panel under the dashboard on the driver's side to reveal the fuse box.
- Consult the diagram on the inside of the cover to locate the target circuit.
- Remove the blown fuse with the fuse puller and replace it with a fuse of the identical amperage rating.
- Close the panel once the fuse replacement or inspection is complete.
If you’re unsure which fuse corresponds to a circuit, or if a replacement fuse continues to blow, seek guidance from the owner’s manual or a certified Acura technician.
Summary
In short, the Acura MDX generally has two fuse boxes: one under the hood in the engine compartment and one inside the cabin under the driver's side dash. Each box is clearly labeled with diagrams to identify fuses, and replacements should use the same amperage rating. Always refer to your specific model year’s manual for exact fuse assignments and locations.
