First suspect for that condition is the a/c low speed aux fans/circuit and the two most probable causes for that system failure are the fuse or a slightly low refrigerant condition.

The easy test for this circuit is to put the key on and jumper the two spade connectors at the end of the high pressure sensor wire .... at the a/c reciever/drier..this is the sensor with the 6" pigtail wire leads . IF the fan comes On w/jumper, the4 circuit is verified and the suspect is low refrig....if No, then the suspect is the low fan relay/fuse/ or Resistor, with the fuse being the first suspect ..
