	Just revisiting this issue.  I had assumed it was likely a faulty temp 
flap servo, but when I dug into it, the servo was moving freely as I 
cycled from "Lo" to "Hi".

	I *did* notice that while the lower heater hose feeding the heater 
core, the upper return hose was, at best, luke warm.  Good photo here:

	I did bring up the CC codes, and all I got was a "15.7 Air Flow Flap, 
sporadic block".

	Now what is odd, is every now and then, I will get full heat.  Seems 
like once the car is up to temp, if I shut it down, and restart, I then 
have heat.

	Any idea what I should look at next, what channels on the CC head I 
should be looking at for insights?

	Thanks!
