Help me understand something. For some reason my heat will not blow hot air unless I am driving. Even then It's not that hot. I'm guessing that it has something to do with pressure in the system, but I'm not sure. What suggestions do you have as to what causes this?

my guess is that it just blows in hot air from the engine compartment, so when your engine gets hot, so does the heat. at least thats what mine does.

Are you not getting any air flow when you are sitting still. If not your fan is not working.
