SOURCE: No front heat

Are you sure the temperature door is moving ? I have seen the door break or the actuator not move. It is either the door or the actuator.

I am having/had the same problem. My rear heater has not worked the last 2 winters, still trying to figure that one out. But I think I solved the front heat problem myself. The heater was blowing cold air while idling and hot air when the car was moving.

I jacked up the front of the vehicle, took the cap off of the reserve tank for the radiator, turned the car on and ran the heat (AC off) for 15 minutes. This is supposed to release any air bubbles in the coolant system and I did see air bubbles emerge as I was watching (this might be normal occurance, I'm far from a mechanical expert). Anyway, this did not immediately solve the problem, still blowing cold air as it sat there idling after 15 minutes. Dejected, I put the cap back on, lowered the vehicle and resigned myself to taking it to a dealer.

But a funny thing happened the next day, the coolant level was a lower (no leaks on the floor) so I filled up, and sure enough, when I started the car and let it warm up a little, hot air started coming out of the heater!!!

As far as my wife knows, I fixed the problem for the price of a bottle of coolant, so I am a hero...but at first I thought it didn't work. Here we are a month later and still blowing warm air and haven't had to replace any more coolant...the internet is a wonderful thing!

Hope this works for you, and I hope I can figure out my rear heater problem as well.

Yes the o5 outback has a cabin air filter and it is located behind the glove box. You have to remove the glove box, once you get it out of the way you will need to remove the 4 metal clips that hold it in place and make sure you put the filters in with the arrows pointing in the right direction for air flow. Other wise you will have restriction through the vents

SOURCE: driver's side air blowing warm, won't change

Sounds like there is a crack in the vent that leads to the drivers side, and hot air from the engine is leaking through.
