I'm pretty sure that this isn't normal, but i'll ask any way. A few weeks ago, someone was asking about how the heater was blowing cold air and someone suggested turning the nob to somewhere that i can't exactly recall. I just did a search and can't seem to locate that thread, let alone do a search for "heater" (also, not to hijack on my own thread, the search doesn't seem to go back to more than a year, if that anymore). Can anyone tell me what's possibly causing the heater to blow cold air? However, when the mode is set on the "floor" (direction of air flow), the heat does come out. Thanks again.
