AC stands for the activation of the compressor, which is used for cooling. If the compressor is not turned on, only the fan will start. If the compressor can be activated but the AC switch cannot be turned on, then the AC indicator light is likely damaged. Here are the letter markings on the car air conditioning system: 1. AC: The A/C button is the switch for the air conditioning compressor. Only when the compressor is turned on can the air conditioning provide cooling. When the A/C light is on, it means the compressor is working, and the car's air conditioning can cool. 2. MAX: When the MAX function is activated, the car's air conditioning will operate at full capacity, with the fan at maximum speed. This function is only available in some models with automatic air conditioning. Pressing MAX will make the air conditioning compressor and fan use maximum output to quickly reach the set temperature. 3. FRONT button: This is the front window defrost switch. When turned on, the air vent will blow air toward the front windshield. 4. REAR button: This is the rear window defrost switch. When turned on, the rear windshield's electric heating wire will heat up.

What Causes the Noise When the Air Conditioner is Idling?

The reasons for the noise when the air conditioner is idling include ignition system failure; poor quality engine oil; excessive carbon buildup or aging of the engine; abnormal fuel supply pressure or incorrect readings from the intake pressure sensor. Cleaning carbon deposits from the fuel injectors: Since the combustion chamber is prone to carbon buildup, which can cause difficulty in starting, carbon deposits on the fuel injectors can also lead to clogged fuel passages, distorted fuel injection, and poor atomization, naturally increasing fuel consumption. When selecting engine oil: It is necessary to strictly follow the engine oil grade specified in the car's user manual. If the same grade is not available, a higher-grade oil can be used, but a lower-grade oil should not be substituted.

Is it acceptable to park an automatic transmission car in neutral (N) and then turn off the engine?

It is not advisable to park an automatic transmission car in neutral (N) and then turn off the engine. The N gear is the neutral position, which can be used for brief parking. Automatic transmissions do not require the driver to manually shift gears; the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. The correct parking procedure is as follows: 1. Press the brake to come to a complete stop; 2. Shift the gear from D (drive) to N (neutral); 3. Engage the handbrake and turn off the engine; 4. Release the foot brake, but do not turn off the power, to ensure the car is completely stabilized by the handbrake; 5. Press the foot brake again and shift the gear from N to P (park); 6. Release the foot brake; 7. Turn the key back, switch off the power, and remove the key.
