What does it mean when the 'auto' light keeps flashing in a Nissan Sylphy?

It may indicate a fault in some circuits of the vehicle's computer system, or the car's onboard computer may be experiencing issues recognizing the anti-theft chip. Below is related content: 1.

I've been driving a Nissan Sylphy for several years, and when the AUTO light keeps flashing, it's usually the air conditioning system sending an alert. The most common issue is a faulty sensor, like a dirty or failed temperature sensor, which prevents the system from automatically adjusting the temperature. It could also be a bug in the electronic control module or poor contact in the relay. Check if the air conditioning fuse is blown—locate the fuse box and inspect the corresponding fuse (usually marked in the manual). If a simple power reset doesn't work, take it to a professional shop to scan for trouble codes. It's not a major issue, but delaying repairs can lead to uneven cooling, making summer drives uncomfortable. I personally clean the sensors regularly to avoid dust buildup. Remember to drive safely—if the flashing light is accompanied by unusual noises, pull over and check.

Buddy, as a fellow Sylphy owner, that AUTO light flashing usually indicates failed AC self-test. Three likely causes: sensor malfunction, control unit glitch, or compressor seizure. My car had this last time - DIY fix: turn off engine, disconnect battery for minutes then reboot, sometimes resets. If persists, consult manual to locate issue, DIY clean sensor (near air vents). Flashing doesn't affect basic driving but disables auto mode, temporarily use manual fan control. Avoid tampering with circuits, find reputable shop - fixes for tens of bucks, hassle-free.

The AUTO light flashing indicates an abnormality in the air conditioning system, which can be distracting or cause discomfort. When the light flashes, the system may not be able to properly adjust temperature or airflow. It is recommended to manually set the air conditioning mode immediately. The cause is often component failures such as sensor errors or control board issues. Have it checked as soon as possible to prevent worsening. Safety first—don't ignore small issues.
