Why Saturn coolant fans run constantly?

Saturn coolant fans may run constantly due to a faulty thermostat that is stuck in an open position, causing the engine to overheat. Additionally, issues with the coolant temperature sensor or a malfunctioning engine control module (ECM) can lead to the fans running continuously. It's also possible that there is a wiring issue or a relay stuck in the "on" position, causing the fans to operate without the proper signals. Regular diagnostics can help identify the specific cause of this problem.
