My car sat for a few months and now the rear AC blows warm air while the front blows cold. Rear blower still works but doesn't blow cold. What needs to be fixed? Is it a faulty duo valve in the engine bay?

I'm in Texas and I need every bit of this AC system to blow as cold as possible to keep up with high 90s temperatures.

2006 S65 AMG w/ 90k miles for reference.
