This happens when the right or left temperature blend door actuator goes out. This guide can show you how a typical system works and where the actuators are located. I have included diagrams for your car below.

This could be a blend door issue if you have dual zone temperature control. If this is single zone then most likely the arm that connects the two doors has fallen off or broke.

Here s a guide that will help with this:
