My son has 2006 Subaru Impreza that has a manual air conditioner. There is the lever that switches from inside to outside air. It is broken and stuck (I can shove a key or something in there to move it but it doesn't even move half way) it is stuck on inside recirculation. Does anyone have any videos/pictures or a walkthrough on how to fix this so it slides? I am not so concerned about the lever being fixed but want to move it so it doesn't fog up the inside. Picture below is an example (and mine is stuck on the other side). I have searched but cannot find anything specific to an Impreza. I think its behind the glove box somewhere but how much do I need to tear apart to fix this?
