The smaller fan is the condenser fan. It should come on when the compressor engages. If it doesn't you will have high head pressure and and cool not cold air.

You might have a blend door problem letting in heat as a mix.

Suggested Repair

Adjust the blend door cable so the blend door closes fully and does not mix hot air with cold air. Also confirm the smaller condenser fan comes on when the compressor engages.

Conversation Summary

The owner of a 1997 Hyundai Elantra reported that the A/C was not cooling despite a full refrigerant reading, a working blend door, and a compressor that engaged immediately. The low-pressure hose was very cold, and the owner asked which of the two radiator fans served the A/C. The expert identified the smaller fan as the condenser fan and said it should run with the compressor, otherwise head pressure would be high and the air only cool. The expert also suggested a blend door might be mixing in heat. The owner later confirmed the blend door cable was not closing the door completely and adjusted it using a Chilton manual, which resolved the mixed hot and cold air.
