Fan Function Problem Update - '87 5KCSTQW

["Paul F. Levine" <paulevi@psd.k12.co.us>]

Well, 

Here's where it's at now! In my '87 5KCSTQW this is the situation:

--Fan comes on only high after getting hot (almost 3/4 mark on gauge)
--No sign of medium or low fan speed happening
--No fan with AC
--No after run fan but, yes,I do have after run turbo cooler, and electric 
	coolant pump
--Replaced thermofan switch on radiator with no improvement
--Series resisitor shows open between terminals 1 & 3 and between 2 & 3

I'm assuming I should just replace the series resisitor at this point but 
am concerned that something else might be a fault which might burn it up 
or it's something else (like the relay - which I don't know how to test 
or short)

Any more thoughts?

And by the way, thanks for the help so far...
