I just checked my blower strip fuse. It's just in front of the large fuse box (headlight side), the unit is screwed into the shock tower. It has two cables running into it, one in the front and one in the back. The cover flips up from the long side.

Hope this description helps. If the fuse is okay look at my post regarding testing of blower.
