I'm in the same boat. I believe the answer is one you aren't going to like
though! The blower housing and such all rest in a very hot place, and
basically your 'cool' outside air is just getting heated up by the super
high underhood air temps that our cars suffer from. In my case the heater
valve isn't leaking, and the heater core isn't getting too hot, and the
entire HVAC casing under the cowel is very hot to the touch. Of course even
without coolant flow the heater core will still heat up just by the heat
conductivity of the water and hoses. 2+2 = No refigerant flow means windows
down ;-).
It is also possible that your heater valve is leaking, or that it's being
falsely opened. Try taking cobram's advice and clamping off one of the
heater hoses. I suggest something like this design:
