Heater goes cold

Hi. 997 Carrera 2 S 2008 68k. Gen 2.
 Help After driving for about 50miles the heater go's cold so turn the temp up
do this 2-3 times, 
it go's cold again so now we are at full heat it will stay there and cook you.
Where to look first, lost control over heater temperature,
Poss vacuum leak.

    Charles,
     
    I'm sure that someone with your extensive experience has probably looked at the obvious things, but if your 997.2 has climate control, maybe there's a problem with the cabin temperature monitor? Do you get the same problem when in non-auto temperature mode?

    Yes, as Jeff suggests, Charles, this sound suspiciously like cabin temp monitor not doing it’s job (very common on the 993 too). Worth locating it and getting all the fluff out of it for starters, perhaps?
