Wiper timing

Hi all new to the forum but not new to the idiosyncrasies of the Windstar. Anyway I have an interesting problem and wondering if anyone has any suggestions? I have a 96 Windstar and no matter where I set the wiper switch the delay is the same. It seems to be at the longest delay no matter where it's set. Any ideas?

Hard to believe no one has run across this before. :confused:

I would say it is the multi function switch. that is where the resistor set is for the delay settings

Thanks for the reply yes I was thinking the same but wasn't sure if the control for the delay function was in the switch. I'm leaning in that direction tho because the washer doesn't work either.
