The reasons for no response when pressing the AC button are: 1. Compressor damage; 2. Compressor clutch damage; 3. Partial circuit malfunction. The AC is the air conditioning cooling switch. Pressing the AC button will gradually lower the temperature inside the car. The functions of the car air conditioning system are: 1. Using the continuous transformation and circulation of refrigerant to achieve cooling effects; 2. Drawing in external fresh air for ventilation and air exchange to prevent windshield fogging; 3. Utilizing engine coolant, waste heat, or heat generated by a burner as a heating source, which is then heated by the heater and blown into the car by the blower to raise the temperature and achieve a warming effect.

How to Turn On the Cornering Light?

Cornering lights will automatically turn on when the car is making a turn. Here is some relevant information about cornering lights: 1. Turning on/off: When the driver turns the steering wheel, a separate set of bulbs on one side will light up to help illuminate the blind spot in the curve while driving. Shortly after the steering wheel is straightened, the cornering light on that side will turn off. 2. Auxiliary function: During driving, turning on the front fog lights ensures that the driver can see the road conditions in real time, providing a certain auxiliary function for turning. Front fog lights do not have focused beams; the scattered light has a wider coverage range. Since front fog lights emit scattered light, although they do not illuminate far, their brightness is generally higher, which can significantly affect oncoming vehicles.

What is the function of the auto start-stop feature in the Lavida Plus?

Auto start-stop system can improve fuel economy and reduce exhaust emissions. Introduction to auto start-stop function: By installing an enhanced motor with idle start-stop function on traditional engines, the engine completely shuts off when the vehicle meets idle stop conditions. When the vehicle needs to start moving again, the idle start-stop motor system quickly responds to the driver's start command, rapidly restarting the engine for instant engagement, thereby significantly reducing fuel consumption and exhaust emissions. Introduction to Lavida Plus: The Lavida Plus is a compact sedan under the Volkswagen brand. This model is equipped with three engine options: a 1.2L turbocharged engine, a 1.4L turbocharged engine, and a 1.5L naturally aspirated engine.

Effects of a Loose Motorcycle Chain?

Motorcycle chain looseness can cause the speedometer sensor to malfunction, accelerate wear on the chain and sprocket, and consume engine power. Below are specific details about motorcycle chains: 1. Function of the Chain: The motorcycle chain is the connecting component between the transmission output gear and the driven wheel gear. If too loose, it cannot ensure the transmission ratio and power transfer; if too tight, it is prone to wear and breakage. It is best to promptly inspect and replace a loose chain at a repair shop. 2. Impact of Improper Maintenance: If the chain is not maintained for a long time and the lubrication is poor, it will generate greater friction resistance during operation, resulting in some loss of engine power. Long-term rough operation may also lead to chain loosening or even detachment. Therefore, regular maintenance such as cleaning and lubrication is necessary for the chain.

Why Does the Brake Pump Fail?

Brake pump failure can occur due to the following reasons:1. Quality issues with the brake pump: The brake caliper is not a wear-prone component, and its failure is mostly due to quality defects. Dirty brake fluid can clog the brake lines, increasing pressure on the master cylinder. Over time, this leads to ineffective braking and potential damage to the pump.2. Caliper damage from delayed replacement of brake discs and pads: Continued use of worn-out brake discs and pads beyond their limits can cause caliper damage.3. Poor quality or aged brake fluid: Inferior or deteriorated brake fluid can corrode the master cylinder's sealing diaphragm, leading to poor sealing over time. This results in the inability to maintain oil pressure, ultimately causing pump failure.
