Hi, i have a 2008 sti hatch, since the car came back from having the engine forged i have had an issue with the heat in the car,i have noticed tonight though that on the passenger side it blows hot hair and on the drivers side the air is still cold, it doesnt have dual climate control so i have no idea how to rectify the issue , any suggestions would be a great help, i dont know if there are and levers or switches i need to move at all

thanks
