Heater Problem

[deloreanss@xxxx]

I am having a mysterious problem with my heater. The problem is that there is 
no heat. I am speculating that it could be the hot water valve that allows 
the hot water to flow into the heater core, but I do not know how to test 
this theory. I don't think that it could be the heater core b/c I would think 
that would be evidenced by a leak or something. The only other idea I have is 
that the vacuum actuator that opens the heater flap isn't working, but I 
would think that would be the least likely scenario. Does anyone have any 
ideas?

Thanks,
