Heater Advice

["miltdanfoss" <dan.foss@xxxx>]

I have a question I'm hoping can be answered or at least you all can 
steer me in the right direction.

My A/C is out, which may not end up being such a bad thing, since it 
has helped me notice that with the fan on, heat setting to cold, and 
selector in any position, I get cold air out of the vents, but heat 
from under the dash. It is not blowing that I can feel, there is just 
heat emanating from there. It makes the D unbearable to drive without 
A/C here in central Florida. 

However, when I turn off the fan, the temperature with the windows 
open is bearable. Only with fan on does it get real hot in the car.

A friend suggested that my "hot water valve," might not be working. 
This is the valve in the heater core line, with the odd looking 
vacuum operated valve just forward of the engine on the passenger 
side.

Any body have any dealings with this or can offer me advice on how to 
test? I figure I'll need to pull it out, which is a bummer since I 
just got it all bled after I installed my own version of the auto 
bleed (with clear tubing).

Thanks,
