When I turn on the heat in my impreza the air is only warm on the driver side, the passenger side is still cool/cold. Weird thing is I'm pretty sure the A/C is still working on both sides, but its hard to tell seeing how it's 30 degrees outside.

I've been looking for part diagrams so I can narrow down what would cause this, but no luck. Anybody know what might cause this or know where I could find a good heating/cooling system diagram?

Well, I didnt have this issue, but when i took off the vents and the big cover that goes around the radio and vents, I noticed that the passenger side vents were not connected correctly, and caused less air flow to travel at the passenger side. So this may be an issue, and the gap may be big enough to push cold air into the passanger and hot air into the dashboard,
