I'm new to this forum but wanted to say that my wipers have started to do the same thing and not turn off.... very annoying... We bought ours as certified pre-owned and opted for the extended bumper to bumper warranty, will this be covered by this warranty? If not I see the part is Motorcraft SW-7037. Will replacing this do the trick and make the wipers stop doing whatever they want? How hard is to replace this switch, does anyone know is someone has done a write up on how to replace this?
