Windshield wipers on 1990 36 SP

[Dave]

Hi all. I am sitting in office park on the side of the road in Raleigh
NC on the way home from a weeklong trip. I can't get the wipers on, I
don't recall if I have even tried to use them since I bought the coach
in January. I checked the fuses in the front outside access panel,
they check good. Any other ideas. Looks like we may overnite here if
the rain does not let up.
Thanks,
Dave
