Hey guys, with summer coming up I've been using my AC system a bit more and as I was driving my passenger said it wasn't blowing cold on them. I put my hand next to the vent and it was blowing semi cool air when my side (the driver's side) was blowing super cold air. I have a 2013 Lancer SE and it doesn't have dual AC controls. So I have no idea what would cause this to happen. Any ideas?
