I had the leak into the passenger footwell which my Ford dealer fixed under
warranty. I recently removed the black plastic cover over the air intake
housing to see what the he had done, expecting to see that sealant had been
applied. Their fix was a suprise: they simply inserted a piece of plastic
coated cardboard (the kind use in car widows to show the price.) over the
air intake housing. They had duct-taped two pieces together and shoved in
in so that it formed an arc over the housing, so that the water runs off of
the top and air can get in on the sides. I doubt that this is what is in
the TSB, but it works.
