Ac problem on 93 Camry on 1993 Toyota Camry

Hi, I have a 93 Camry. When I run the AC all the vents blow air but only one vent blows cool. What could be the problem?

The system could be low on refrigerant, or there could be a problem with the system that controls the temperature and air flow through the vents.
