Black plastic cowling below the wipers...
My wiper cowl was coming up on the drivers side aswell and the dealer put a F*CKING screw threw it to keep it in place!! Me not noticing at the time when i had warranty didnt think twice about it it thinking i got it fixed but now that i have no warranty it really pisses me off because they half assed it and didnt even attempt to replace it.
I took mine in a few weeks ago for the same thing. They said Ford has a clip for the fix. Mine is fine now.. no screw. guess I should look under the hood and see if I can see what they did.
