Poor Defroster Air Flow - any experience

I had the same problem as Kevin on my FIRST flight up north a few years ago. Damn cold with no heat at 10,000' in December!!! It was an improperly connected duct, and an unpleased spousal unit and toddler contingency - if you hear what I'm saying.

Since then, I've not had any problems, and always fly with blankets and a space heater as back ups - but have not used them in necessity . . . .

I believe the true experts on this should be, at a minimum, Larry and Gerry.

Gents? Any problems or suggestions?
