I have something gone really whacky with my wipers. When they are off they are like they are on intermentant 1. I did get them to to stop by putting them on Intermentant 1. I replaced the wiper motor thinking that maybe the circuit board in it was bad...............guess not. Now they will not shut off. In the off position they are like Intermentant 1 and Intermentant 1 is normal. Does anyone have any idea what it could be??

 

Typical Ford "GHOST" wipers. You most likely have a failing/failed Multi-Function switch. This is the whole turnsignal/wiper unit. Fairly easy to replace.
