Same gig as mine ('87 Westfalia GL) except it's position 4, I replaced the
switch but, alas, it was no help........looking into this further.

I have a 87 with the overhead system, what exactly controls the fan speed, 
there is a 4 position switch, but I have nothing on 3, I took the switch 
apart and it seems to be functional, is there a relay pack or resistors 
somewhere to check?
