okay, CEG: Does the clock spring feed the wipers, too?
as another option:
Check in your owners manual (if you have one) for which fuse operates the wipers.. the fuse box is located underneath the dash, on the driver's side, right about where your knee is, when you are sitting in the seat. There is a little lever that you pull down to get the fuse box to swing open (downward) for access...
a bad wiper motor could make it not work in any mode, as well. The wiper motor is, obviously, underneath the plastic cowl that runs the length of the windshield, on the outside. Removal of the windshield wipers themselves are required to remove the cowl.
