The fuse boxes are located in two places: the engine compartment under the hood and inside the cabin behind the glove box.
In the 2008 Honda Odyssey, the under-hood fuse box (also called the fuse/relay box) provides power to major engine and electrical systems, while the interior fuse box covers most passenger electronics and convenience features. This guide walks through where to find both boxes and how to use the fuse diagrams typically printed on their covers.
Under-hood fuse/relay box
Open the hood and look for a black plastic fuse/relay box mounted in the engine bay, usually on the driver’s side near the front or near the strut tower. The box cover features a diagram showing which fuse or relay protects each circuit. If you’re replacing a fuse, pull the old fuse straight out and snap in a new one with the same amperage rating.
- Fuses and relays that power the engine management system, fuel system, and essential engine sensors
- Fuses for ignition, main power supply, and electronic control modules
- Fuses for lighting (headlights, turn signals) and cooling fans
- Fuses for ABS, traction control, and other safety-related systems
- Fuses for accessory power feeds (other high-drain components may be protected here)
In most cases, the fuse/relay box cover includes a map identifying each circuit by number and function. If a circuit blows, replace it with a fuse of the same amperage and check nearby wiring for damage. If the fuse repeatedly blows, there may be a short or faulty component that requires professional diagnosis.
Access and safety tips for the engine bay box
Disconnecting the battery isn’t typically required to replace a fuse, but exercise caution around hot components and moving parts. Wear eye protection, use insulated pliers if needed, and ensure you’re using the exact amperage rating specified on the fuse map.
Interior fuse box
The interior fuse box is located inside the cabin, typically behind the glove box or on the side of the dash on the passenger side. Access usually involves opening or lowering the glove box and removing a small panel or the fuse box cover to reveal the fuses and their designations. The interior box handles fuses for the stereo, HVAC controls, power windows, door locks, and other cabin electronics.
- Fuses for the radio, climate control panel, and infotainment features
- Fuses for interior lighting, dash lights, and instrument cluster illumination
- Fuses for power windows, power door locks, and other convenience features
- Fuses for accessory outlets and miscellaneous electrical circuits
Like the engine bay box, the interior fuse box cover includes a diagram listing fuse numbers and their corresponding circuits. If a circuit stops working, check the affected fuse first, using the same amperage rating as indicated on the cover. If the fuse blows again after replacement, there may be an underlying electrical issue that requires a professional inspection.
Access and safety tips for the interior box
Support the glove box or panel securely when removing the cover to avoid damage. Keep track of which fuse corresponds to which circuit, and avoid using higher-amp fuses to compensate for a faulty device, as that can cause wiring damage or fire risk.
Summary
For a 2008 Honda Odyssey, there are two fuse boxes to know: one in the engine compartment under the hood and another inside the cabin behind the glove box. The engine bay box powers essential engine and safety systems, while the interior box handles most cabin electronics. Always refer to the fuse diagrams on the covers for exact fuse numbers and functions, replace blown fuses with the same amperage, and consult a mechanic if a fuse continues to blow.
Where are the fuses on a Honda Odyssey?
Passenger Compartment – Fuse Box A Location: Under the dashboard on the driver's side. (Fuse locations shown on the side panel label.) 2. Passenger Compartment – Fuse Box B Location: Under the dashboard on the driver's side, near Fuse Box A.

So for the second one you'll need to open the hood of the car by pulling obviously this hood release here and the footwell off the driver's. Side then go in the front of the vehicle. Open the hood.
Where is the secondary fuse box located?
The secondary under-hood fuse box is next to the battery. To open it, push the tabs as shown. If something electrical in your vehicle stops working, check for a blown fuse first. Determine from the chart on pages and , or the diagram on the fuse box lid, which fuse or fuses control that device.

And it will just slide out. And then you will have the access to all of the fuses. Okay now the second fuse box will be just on the opposite.
