Windshield wiper's fuse location needed

Fuses rarely blow for no reason. Were the wipers blocked with snow or ice or did they just stop working? Do the washers still work, just not the wipers?
There are a couple of possible fuses depending on the option level of your car. The upper level vehicles have a wiper fuse (number 20) under the hood in the fuse and relay box B on the left of the engine compartment. Shown in first picture. The lower level cars don't have an individual wiper fuse, they instead have power coming directly from the vehicles electronic control module and only have control fuses (numbers 8 and 10) in fuse box C located at the end of the dash inside the car.
