Happend to me. Just replaced the switch and good to go again.
the faster 4th position does not work.
If it comes to that, where can I get one? Is it still available at ford?
Well it could be that you have stuff clogging your vents, and maybe the speed change isn't noticeable because the fan is already supplying more air than the ducts can handle. I just pulled the fan on Lady Moose last weekend, and removed enough mouse nest material (made out of the bottom of my seats, and floor mat! ) to fill a 2 gallon bucket.
