Why does the A/C only blow warm air on driver side and cold air on passenger side?

What is your question?

When I turn the air conditioning on in my 2013 chevy cruze it only blows warm air from the vents on the driver side and cold air from the vents on the passenger side. I replaced the passenger compartment air filter and it still does the same thing. It just started doing it this week.

What makes this problem better or worse?

Nothing

How long has your 2013 Chevrolet Cruze had this problem?

A week
