Great news! I have a mechanic I work with and he does many British cars. Many 
times they arrive with a "problem" and as soon as he starts to look at the 
"problem", it's fixed! Don't know why or how, but it's working! Around the shop 
we call this "FM". Loosely translated it means: F**king Magic!
   Glad to hear you're up and running again and if my heater motor ever 
needs attention, I like your idea of closing off the top vents, thanks for the 
suggestion.

About an hour ago I popped the spring clips off of the heater face-plate which 
gave me access to the back of the rheostat switch. I first verified that there 
was power to the switch and then jumped across the two posts with a 
screwdriver. The heater motor came on full blast, telling me that the problem 
was in the switch, which had felt a bit odd when I initially encountered the 
problem a few days ago as the "detent-like feel" when turning the fan on was 
missing. Though I assumed I had identified the problem as being in the switch I 
nevertheless turned the control knob just to see how it felt and--wonder of 
wonders--the fan motor immediately came on. What's more it responded perfectly 
to the rheostat, going from full blast to low just as it always had. 


I am 100% certain that I had the ignition switch on and the heater power lead 
connected with an intact fuse and I can only say that this is a typical Healey 
deal, and now that the car has my attention I am sure that should I simply 
close the heater up the switch will probably act up at some point in the 
future. I'm going to investigate whether I can source a replacement switch, 
either Lucas or not. I'll also take the opportunity to repaint the front plate 
in black crackle and I am going to close off the top opening that supplies 
heated air to the two vents in back of the windshield, which seems like a waste 
of hot air.

Thanks all for your patience and advise and I hope this gives some of you who 
have experienced similar situations a laugh.
