How do i fix the automatic feature on my acura mdx?

the automatic feature of the windshield wipers in my 2005 acura mdx stopped working i assume it is the fuse it says there is a fuse for it in the manual and there is also a diagram next to one of the 4 fuse boxes that i have found that says automatic windshield wiper fuse and there is supposed to be a 5th box with only 3 fuses that has what i am looking for but i cannot find it|||You could always take it to a mechanic or Acura.
