From the Original Post:
[in Manual Mode] "65=LOW corresponds to no heat added"
This statement doesn't seem to be true on my car. Once the engine has really completely warmed up, with the fan on outside air and the dial set to 65, the air coming in the vents is noticably warmer than the air coming in through the windows. I know it might not be possible to bring air in through the engine compartment without transfering some heat to it, but it seems like the air is being warmed quite a bit. In my previous car the air coming in through the vents was pretty close to outside temperature even with a hot engine.
Has anyone else noticed this on their car?
BTW, mine is an '05 Outback XT, but I'm assuming that this issue would be the same for the Legacy.
