The heater valve is probably not working correctly. It is a vacuum-
applied function to turn it off so a vacuum leak should leave it 
turned on and you should have heat. I have experienced two typical 
problems here. The mechanical heater door that moves air across the 
heater core is not adjusted properly - they can be tricky to adjust 
and get ALL the air to go across the core, OR, the heater valve is 
faulty. I never thought the heater in my car worked effectively. 
This last year I changed the heater valve and upon inspection of the 
old valve I discovered that the valve itself was either assembled 
incorrectly or the shaft had moved on the open-close arm; in any 
case, the valve was basically closed all the time. I have good heat 
now. I just drove it yesterday in 30 degree weather, worked fine. 
So, the heaters work if you get the stuff to work correctly.
