There aren't hoses involved, but a blend door box controlled by electric motors. You need to research blend door motors and blend door repair kits, or find an indy. This is a very common issues with 9-5's but lots of other cars as well. Start with Auto and OFF held down at the same time to get a diagnostic code out of your ACC unit, then start googling that code.
Good luck, welcome to TSL.
