Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
Hello, so your concern is that the radiator fan is not turning on when the car gets too hot, but it works when the air conditioning is turned on?
OK, let me look up some things and determine what is happening.
Alright, after looking at the diagrams and considering what you told me it looks to me like the temperature sensor is bad and is commanding the fans on all of the time. Check the connector for corrosion and the wiring for damage, also try unplugging the sensor while the fans are on. If the fans go off, replace the coolant temp sensor. Another thing you may want to check is the radiator fan relay. Swap the relay with another one and see if anything changes.
