Problem solved (I think)
Behind head light found green 3 wire resistor with a burnt wire. The
ceramic crumbled when I removed it.  Was able to get the last 2 digits
off it for the parts man. $42
Yes I have A.C.
The real problem I had was I couldn't reconcile the schmatic(years 90+
(with out resistors)) with the real thing.  after much frustration,
paged through Bentley and found my 90(built in nov.89) in the 86-89, 450
watt fan schematic. It must have been a running change.
I'm sure the fan will run on low speed now.  Hopefully nothing is wrong
with the motor/bearings.  It runs great on high.

That's kind of strange, because my old 2WD 1986,
no AC, had a 2 speed fan, but no resistor at all!
Go figure?
