Hello, thank you for writing in. When diagnosing a fan problem like this you must consider that the fans are technically working. They are simply not being switched on when they are supposed to. You may be looking at a coolant or a coolant temperature sensor issue. Since you have replaced the thermostat and the temperature sensor already, you want to focus on their circuit. If the coolant temperature sensor has failed again, it is likely a wiring problem with the circuit causing it to fail prematurely. If all seems well, make sure that the thermostat is working correctly and that the coolant is flowing properly through the system to begin with.
