My air vents blow out air. That's it. They do it well, too. Two weeks ago, when I turned it to high heat, the air was HOT.
But now it's just air.
The AC doesn't work either, but I know where that problem comes from. But what would cause the heat to cut out? I thought the hot air was just fanned in from the engine, so it should be heated automatically...this seems strange to me.
EDIT: I drive a 97 Subaru Legacy; I know nothing else. :)
