your cooling fan thermostat is worn out. it is a thermister, which means it varies voltage depending on temperature. the reason it will come on when the air conditioning is on is because the air conditioning circuit contains a high pressure switch on the high pressure side of the air conditioning system which is normally open, meaning it doesn't complete the circuit until high discharge pressure from the condensor closes the contacts in the switch, thus completing the circuit, which sends power to the cooling fans, thus causing them or it to come on and try to "cool" the air flowing through condensor. check with your local auto parts store for availability. ---JT---
