Cooling fans may not turn off due to several reasons, such as a malfunctioning temperature sensor that incorrectly signals the need for cooling, or a problem with the fan control module that fails to respond to the system's requirements. Additionally, continuous operation can occur if the system is still overheating or if there is an issue with the thermostat. It's also possible that the fans are operating as designed, especially in high-load conditions. Checking for error codes and inspecting the relevant components can help diagnose the issue.

Why do fans turn on and off while 98 Subaru is off?
In a 1998 Subaru, fans may turn on and off while the vehicle is off due to the coolant temperature sensor or engine control unit (ECU) activating the cooling fans to prevent overheating. This can happen if the coolant temperature is still elevated after the engine is turned off. Additionally, a malfunctioning relay or electrical issue could cause the fans to operate unexpectedly. It's advisable to check the electrical system and cooling components if this behavior is persistent.
