I'm not sure about the fuse box layout on that model, but I do have a tip for finding fuse related problems. Get a cheap test light and connect the alligator clip to the negative battery terminal. Roll the key to the RUN position ( do not start). Look carefully at the fuses while they are plugged in. You should see a little silver tab on both sides of the top of each fuse. Touch one with the probe of your test light. It should light up. Now touch the other side. If it doesn't light up on both, the fuse is blown. If it doesn't light up on either side, then there is no power getting to the fuse and you'll have to do more digging, but it may be normal. Some circuits are only energized under specific conditions.
