Is it normal for the car's fan to keep running when the air conditioning is on?
2 Answers
It is normal because when the air conditioning is turned on, the air conditioning compressor starts working and requires the fan to dissipate heat. Below is relevant information: 1. Introduction: Automotive air conditioning refers to the air conditioning device installed in a car, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. 2. Structure: It generally includes cooling devices, heating devices, and ventilation devices. This combined system makes full use of the limited space inside the car, has a simple structure, and is easy to operate, making it a popular modern automotive air conditioning system internationally.
I'm the kind of person who pays close attention to details while driving. It's actually quite common for the fan to keep running when the AC is on. The AC cooling requires the compressor to work, and that thing gets really hot. The fan has to keep spinning to dissipate heat and prevent the engine from overheating or seizing. Especially during hot summer days, if you're on a long drive or stuck in traffic, the fan noise might be louder, which is completely normal by design. But if the fan keeps spinning wildly after the AC is turned off, or if you smell burning or see the engine temperature gauge skyrocketing, there might be an issue—like a faulty temperature sensor or electrical circuit problem. I recommend keeping an eye (or ear) on changes in fan noise—don't ignore small signs. Get the fan system checked regularly at a repair shop. Spending a little money now can buy you safety and peace of mind later.
