Hello and welcome to just answer. The fans are controlled by the AC pressure transducer on the high side line. If the pressure is low (low refrigerant level) or the transducer fails then they will not come on. First verify that there is the proper amount of refrigerant in the system. if so, then suspect the pressure transducer and have it replaced. It simply threads onto the port. No need to discharge the system when replacing it because there is a Schrader valve in the port.
