It is just under the dash behind a removable panel. Look below your headlight switch on the driver side just inside the car. Right under there is the storate bin area. There is a panel there that simply pulls out. The fuse box is behind and the diragram for which fuse is which is on the back of the panel.Note that if your look up under the dash you can see the fuse box. If you can't immedialty find the panel to remove. Look straight up under the dash in that spot and you will see the fuse box. The panel is directly in front of the fuse panel.

Its under dash on the left side of the steering column mounted in fuse box.
