    I have a similar problem in cold weather, but mine is much colder in
northern NH. There is a known Vanagon problem with the AFM, but I
haven't heard anyone relate it to cold weater.
   But I believe in my case a frost film is developing on the resistance
material, and insulating it from the wiper. (This is what I found in a
test in my freezer.)
     When this happens parking with it idling always cures it.
