Re: No Heat?

Joe,
That is true...but if the vacum line to the water valve itself is the 
only culprit as Nick refered to...then it would always be hot air 
blowing. Even though all the vents are by passed, and it passes cold 
air trhough the vents, hot/warm air will always be coming through the 
defoger vents for the windshield. I am not sure if the Delorean is 
set up the same way, but three cars that I have fixed had a 
broken/disconnected vacum line to the water valve and the heat always 
came through the defrost vents even when the heat/AC was off! It was 
allot noticable as you were driving, standing still you would not 
feel it blow at all. 

What you are describing is if something is wrong with the vacum lines 
in the car causing that bypass door to stay in one position...or the 
door is stuck in the AC mode. I hear a vacum test coming on! :-)
