Why does my cooling fan run all the time in my jeep?

If your Jeep's cooling fan runs continuously, it could be due to a faulty temperature sensor, a malfunctioning fan relay, or an issue with the engine's cooling system, such as low coolant levels or a stuck thermostat. Additionally, the fan may be programmed to operate continuously in certain conditions, such as high temperatures or heavy load situations, to prevent overheating. It's advisable to have the vehicle checked by a mechanic to diagnose the exact cause.
