If the compressor is working and there's enough refrigerant in the system, it could be the inner doors aren't opening. Dust and humidity can cause dirt to cake on the edges of the doors gluing them into place.

Specifically, the mixer door is probably stuck. The motor for this door is on the upper side of the chamber from where the blower resistor pack is. That resistor pack resides in the bottom of the heating and cooling unit (it's a single unit).

I'm not sure if a product like this (it's an Australian store, I know, but you might find something similar locally) would work - if it doesn't, you may have to disassemble the unit.
