1998 Deville Windshield Wipers

I occasionally drive my grandparents '98 Deville, with 69K. I was driving in some light rain last evening and the windshield wipers just quit. Have worked fine up to this point with no issuess. Curious if it may be a fuse or if a motor, does it just quit all at once. Anyone have any ideas and where is the fuse panel and is there a fuse labled wipers?????

Fuse locations are in the owners manual. If you don't have one, you can download one here....

If it's not that then it's likely to be the connection at the motor, the motor itself, or the linkage(s) to the wiper arms.
