Why does the Cruze's fan start running immediately upon ignition?
1 Answers
The reasons why the Cruze's fan starts running immediately upon ignition are as follows: The air conditioning was not turned off: There is no issue with the car's cooling system; it's just that the air conditioning was not turned off during the last shutdown. When the car is started again, the air conditioning operates, causing the fan to run to facilitate the condenser's operation. A malfunctioning water temperature sensor: This leads to the engine's computer failing to detect the water temperature signal, causing the engine to enter a fault mode. Fault mode refers to an emergency state of the engine itself, where when an important sensor or component signal is missing, the engine's computer ensures the engine can continue to operate by working according to a preset mode.
