Wiper Fluid / Clock Work Intermittent

I have a 2004 Kia Sedona. The clock on the overhead console and the wiper fluid pump are both working only intermittently and they alternate working. In other words, when one works the other does not. My mechanic has checked it and has not found anything obvious. Before we spend more time and money on it I am looking for any ideas or experience with this issue. Anyone?

Do they share the same fuse???
