The radiator fan never comes on. I checked the radiator fan relay, and it works fine and there is no fuse as far as I'm aware of. The A/C also cuts out after 3-5 minutes of car running. No codes related to that came up! Already replaced thermostat and also a fan shroud assembly along with a radiator fan module. The problem still persists. I've checked active grille shutters, and they are in open positions after the car has reached normal operating temp. I don't think it's the coolant temp sensor as it is indicating the temperature just fine and I believe the fan stays running constantly when the coolant temp sensor goes bad? No coolant leaks are present either and it is not missing any coolant. At this point I am thinking bad water pump or bad/clogged radiator, however coolant doesn't appear to be dirty or contaminated. Please let me know what you think. Thank you very much.
