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.

Thank you very much for your assistance I located the problem it was the blend door, the blend door cable was not closing the door completely and it was as you said mixing hot air with cold air I followed the red and blue air temp knob and located the cable I then manually adjusted the cable as instructed in my Chiltons repair manual #32102 page 6-21 my wife will now give me my truck back : D : lol: 8) 8) 8) 8)
