wipers won't turn off Wipers In off position , but keep on slowest delay setting. 6 hours driving home from Florida with the freaking wipers going every 20 sec. I pulled fuse, it helps in short term, seems to reset . After wiper used again, problem returns. Dealer wants $300 to replace multifunction switch. May just order one on-line and try to replace myself. Ford says they have never heard of this before, but I have found others on line.
