Yeh, I could see that plastic elbow but could barely reach it with my 
fingertips. I might have been able to pull the elbow out with the aid 
of a long needlenose pliers but was afraid something would break (*). 
I do think that refastening the blower housing might solve the 
problem--even though that hose is still plugged and may overflow. If 
it overflows, the excess condensate should probably just drain down 
into the big (rain) drain, but some of it had been able to seep under 
the gasket. Anyway, that's my story and I'm sticking to it.  :-)

(*) If it ain't broke, don't break it!
