Good information yes, and it's been talked about here before. Folks can search out their problem and save money.
Last year a bunch of these failed; it was assumed the salty roads up north contributed to the failure. Ford mounted them up against that rail by the spare tire, and many think water, mud, and salt from the roads gets between the module and rail, making it corrode and rust out (the metal backing. The fix was discussed and found to be a good solution: install a few washers between the module mounting holes and the rail to allow about a quarter inch or so of space. This way the module back will not trap water, mud, or whatever. Another possible fix is to use some silicone around the edge to keep the water, mud, and grim out.
Also, if your dealer is out of the F150 part, the Mercury part is exchangable; some of the parts guys don't know this.
This was all discussed here last year.
Give an answer, they learn for the day; suggest a search, they learn for a lifetime.
