The main fuse boxes in a 2018 Honda CR-V are located in the engine compartment and inside the driver's side footwell; some trims also include a fuse box in the cargo area. This guide lays out where to look and how to identify the correct fuses for common systems.
Engine compartment fuse box
The primary engine bay fuse box sits on the left side of the engine compartment, near the firewall. The lid or cover panel includes a diagram listing each fuse and its amperage, which helps you identify the circuit you’re working on.
Access and identification
To access it, release the latch on the cover and lift the panel. Use the diagram on the inside of the cover to locate the fuse corresponding to the malfunctioning system (for example, powertrain, cooling fans, or ABS). After identifying the fuse, you may remove it with a fuse puller or a small pair of pliers to inspect or replace it.
Interior fuse box
The interior fuse box is located under the driver’s side dash, typically behind a removable cover near the knee area. This panel protects circuits used by interior electronics and comfort systems.
Access and identification
Remove the interior cover to view the fuse map. Fuses here typically control the instrument cluster, infotainment system, climate control, power windows, door locks, and related components. Always confirm the exact layout with the stamped diagram on the cover, as configurations can vary by trim level.
Cargo area fuse box (if equipped)
On some 2018 CR-V trims, there is a third fuse box located in the rear cargo area, usually on the left side behind a panel. This box protects rear-area electronics and any cargo-related outlets.
Access and identification
Open the cargo-area panel to reveal the fuse map. The fuses here typically service items such as rear power outlets, lighting in the cargo space, and other trunk-area accessories. As with the other boxes, rely on the diagram printed on the cover for proper fuse identification and amperage.
How to identify and replace fuses safely
If a component stops working, check its corresponding fuse using the box diagrams. Always replace a blown fuse with one of the same amperage rating and never bypass fuses to avoid electrical damage.
To replace a fuse, you can follow these steps:
- Turn off the ignition and remove the key; park safely before touching the fuse boxes.
- Open the appropriate fuse box and locate the suspect fuse using the diagram on the cover.
- Carefully pull the fuse out with a fuse puller or plastic tweezers to inspect it.
- If the metal strip inside is broken or the fuse is visibly blown, replace it with a fuse of the same amperage rating.
- Reinstall the fuse fully and close the box; test the affected system.
If a replacement fuse blows again shortly after installation, this may indicate an underlying electrical fault or short, and you should seek professional automotive service to diagnose the circuit.
Summary
For a 2018 Honda CR-V, start with the engine compartment fuse box on the driver's side, then check the interior fuse box under the driver’s dash, and, if your model includes it, the cargo-area fuse box behind a panel. Use the diagrams on each box to identify circuits and ensure you replace fuses with matching amperage ratings. When in doubt, consult the owner’s manual or a qualified technician for precise, model-specific wiring diagrams.
