So our 2014 Hyundai Tucson (GDi) cooling fan doesn't seem to come on when it's hot or when the ac is on. The ac only blows cold when the car is moving and the car sometimes overheats when idling. I had a can of AC Pro on hand that has a pressure gauge on the low side. The pressure read High when I connected the AC Pro and ran the AC so I DID NOT put any freon in. That's also when I noticed that the fan was not running.
I looked at the C/FAN Hi relay and it did not have any corrosion on the terminals or heating. The relay tests good both the solenoid and the switching. There is power to the relay solenoid when the AC is running. There is no power to the switched contacts for that relay. The fan motor runs if I supply it power.
Any ideas of what I can check??
Is there a separate engine compartment condenser fan relay other than the relays listed on this diagram?
PS: The ac system is constantly cycling the compressor on 10 seconds off 30 seconds.
