hello everyone. im in desperate needs of some help trying to find out why my cooling fans dont turn on. i have a 93 legend that keeps overheating. reason is because the fans dont kick on. engine temp gets past half way mark and still fans dont turn on. only time they turn on is when i turn ac on. but even then they cycle off and on and my car will eventually overheat. so far i have checked both relays that are by the upper radiator hose, fuses and relay by rear passanger side of the engine bay. i dont know what else i should check. i dont want to just jump it to were they are constantly running. can someone tell me what all components are related to the radiator fans?
