Hi,

Ok, the verdict.

BLower motor checked out ok.
I removed the blower switch and found the grounding of the 12V source  
(center terminal)
I took Daves guidance and jumpered the actual 12v source coming to  
the switch and that powered the blower fine.  So the switch was toast.

now for the uncharted territory.........

Out of pure determination i spread the four prongs on the back of the  
switch and dismantled it.
i found inside the tabs which were arching from age and wear.
i polished it all with emery cloth (and a shot or two of  
electromotive)  reassembled and was in business.  blower works great!
even have all three positions (talk about modern conveniences!)

 Now its on to find which vaccum line is leaking because heat , cool  
and defrost all work just that when you actuate the control switch  
you have to rotate the vacuum pots by hand.
any tips from the forum on where to start?
i know it could be many places , maybe even the switch itself?

thanks again.
