My Car Fan Keeps Running Even When the Car Is Off: What May Be the Problem?
If your car fan continues to operate even after you've turned off the engine, it could indicate various underlying issues:
- Faulty Fan Switch: The fan switch may be defective, causing it to remain on regardless of the engine's status.
- Overheating Sensor Malfunction: A faulty sensor can trigger the fan to stay on even when the engine is cool, potentially indicating issues with the cooling system.
- Electrical Issues: Short circuits or loose connections in the electrical wiring can result in the fan running continuously.
- Damaged Fan Motor: A failing or worn-out fan motor may struggle to turn off, leading to persistent operation even when the car is off.
- HVAC System Problems: Issues with the heating, ventilation, and air conditioning system, such as a stuck relay, can cause the fan to remain on when it shouldn't.
