I have a 2015 Fusion titanium wipers are only working on high No low No medium and can not spray washer fluid. I have changed the switch on the column twice with Duralast brand from auto zone. going to try one from Ford Dealer. but I'm trying to find the ground wire to the wipers to check that and see if its good. is there anything else it could be.

just trying to see if anyone has this problem with the carpet. it wont stay up under the sill. Ford says that its bc the carpets cut short. Im just wondering if anyone has a fix.
