Is 'no' on or off for car air conditioning?
2 Answers
no is neither on nor off. The on position for the switch is 'on', and the off position is 'off'. Here is an introduction to air conditioning related content: 1. Operation: Press the ac button, and the refrigeration system of the air conditioning compressor will start working. 2. Location: The car ac button is located below the display screen. Here is some extended information about the related content: 1. Function: Adjust and control the temperature, humidity, air cleanliness, and air flow state inside the car compartment. 2. Components of the car air conditioning refrigeration system: compressor, condenser, liquid storage dryer, expansion valve, evaporator, and blower.
Having driven for so many years, I find that air conditioning button symbols can be quite confusing. Generally speaking, the "ON" marking on a car's AC panel indicates the system is active, while "OFF" means it's turned off. Last time a friend rode in my car, she actually thought "NO" meant on—probably a case of misreading the letters due to light refraction. Most modern vehicles follow international standards, though some older models might use indicator lights instead: illuminated means on, and unlit means off. I recommend paying attention to the sound of airflow and temperature changes at the vents when the AC starts—this way you can judge its status without even looking at the buttons. If you're really unsure, checking the icon prompts on the instrument cluster display is always helpful.
