1997 Jeep Wrangler Intermittent wiper multi-switch

The intermittent feature on my windshield wipers has stopped working. I replaced the multi-switch and it still does not work. Anyone have a suggestion as to what I can do to get this feature working again?

The delay is a separate input to the wiper motor and there is a 10 amp fuse for the delay.

Mine has quit and I find it’s a question of positioning the switch just right and pushing forward a little. I have a rubber door stop I use to get it just right and stay there.Replacing the switch looks like a pain.
