There are fuse box diagrams on the 'net but am not sure whether the Royal Exceed's fuse box layout is the same.
I emptied the front washer tank, brown gunk came out of it. I also used the max setting of my garden hose and sent it through the pipe leading to the headlights, more gunk came out (and when the spray went all over the place I realized I might have thought of a better way to do this).
Anyway the pipes are working fine, the tank is clean, but the pump for the headlight sprayers doesn't seem to be doing anything. It either seized up or a fuse is blown somewhere.
