Ric:
I know this sounds *really* basic, almost to the point of insulting 
but DO check the fuse for the fan circuit.  i dealt with overheating 
on my '85 for a couple weeks, condemming the ballast resistors, rad 
sw. etc.  it be the fuse.  even with the fuse blown, the fan would 
come on when the AC switch was on.  however, your reasoning also does 
seem to fit so....  good luck!
