Fuse Box Location
Passenger Compartment Fuse Box
Inside the car, the fuse and relay box is located at the bottom of the instrument panel behind a plastic protective cover.
You must take off the door seal next to the panel in order to reach it. Next, take off the instrument panel’s left end cover. We take off the cover by inserting a screwdriver into the opening. Using a cross-head screwdriver, remove the three screws. Next, we take the big trim from the hooks on the left and drag it under the steering column from the right. We put things together in reverse order. Remember to unplug the speaker and button connectors.
And also through the protective cover, if there is one on the panel.
The block itself looks something like this.
Engine Compartment Fuse Box
There are 2 fuse boxes installed under the hood of the car.
Fuse and Relay Box
The fuse and relay box is located on the left side, next to the battery, and is covered by a protective cover.
