["Fan Controller", "Premium Adjustable Fan Controller Push-In Type"] The fan controller module regulates the speed of an electric cooling fan based on coolant temperature, A/C demand, and other inputs, allowing variable-speed operation for improved efficiency. Signs of failure include: a cooling fan that runs at full speed at all times, a fan that fails to activate causing overheating at low speeds, or a fan that operates erratically. Replace a faulty fan controller to restore proper temperature-dependent fan speed control.
