The car A/C button is the switch for the car air conditioning cooling function. When this button is pressed, the compressor of the car air conditioning system will start working, and the air blown out by the blower will be cold. For example, during hot summer days when you need to lower the temperature inside the car, press this button and then turn the temperature selector switch to the blue section, and cold air will start blowing out. Reasons why car air conditioning may not blow air: Blower failure: The car blower is a crucial component for air output in the car air conditioning system. If the air conditioning compressor fails during use, the car air conditioning will definitely not blow air. Clogged air filter: The air filter is a significant and common reason for the air conditioning not blowing air. During operation, the car air conditioning system absorbs many impurities from the air. Control system failure: It could be due to a malfunction in the air vent, air conditioning computer, or control switch. Generally, control system switches do not fail often. It is recommended that car owners visit a 4S shop for inspection, as this will make the troubleshooting process simpler.

What does it mean when the engine light is flashing yellow in a car?

When the engine light in a car is flashing yellow, it indicates that there is a problem with the car's engine. There are many reasons why the engine fault light may come on, such as poor fuel quality leading to incomplete combustion, oxygen sensor malfunction, air flow sensor failure, spark plug carbon buildup, engine knocking, coolant temperature sensor damage, or the car's computer failing to retrieve engine data. It could also be due to poor engine maintenance causing the engine fault light to illuminate. The vehicle body has more than 10 sensors, any of which could trigger the fault light. Only a computer diagnostic can pinpoint the exact cause of the issue. It is recommended that the owner take the car to a 4S shop for inspection and repair as soon as possible.

How many ignition coils should be replaced at once?

How many ignition coils should be replaced at once depends on the situation: 1. If the ignition coil needs to be replaced due to natural aging failure, and only one has failed, but the others may also be nearing the end of their lifespan, all four should be replaced together; 2. If the ignition coils have not been used for long and one or two have failed while the others are still functioning properly, only the faulty ignition coils need to be replaced. Symptoms of a damaged ignition coil include: decreased engine power, increased fuel consumption, leading to engine misfire. Reasons why ignition coils are prone to damage include: 1. Excessive power generation, causing the ignition coil to be overloaded; 2. Excessive spark plug gap; 3. Poor quality gasoline; 4. Incorrect cylinder compression ratio; 5. Program failure in the computer board.

Can an ETC card be used on another car?

ETC cannot be used when changing cars: ETC is dedicated to a specific vehicle. If both the vehicle and license plate are changed, the owner should first go to the bank to unbind the original ETC-linked bank card. If the new car needs to use ETC, a new ETC pass card must be applied for. When passing through the highway, if the license plate number does not match the information in the card or the tag, passage will not be allowed; moreover, it will be added to the ETC blacklist of the issuing bank. The owner's original ID card and the original vehicle registration certificate must be taken to the ETC service outlet of the issuing bank to remove the ETC blacklist. If the car is changed but the license plate remains the same, simply take the ETC device to the service outlet, have the bank update the license plate number, engine number, and other information, and then reinstall it. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, the owner must provide the original and photocopies of their valid ID card and vehicle registration certificate. If the application is made by a non-owner, the agent's valid ID card must also be provided. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. A bank card for deducting highway toll fees is also required. Applicants must be between 18 and 60 years old, and the vehicle must be registered under their name. Below are the precautions for installing ETC: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have a large rearward tilt angle on the windshield, which can reduce the driver's field of vision. If ETC is installed without considering this, it may increase the driver's blind spots. Install it behind the rearview mirror on the right side to avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back that can charge itself. Therefore, during installation, avoid the blackened areas on the windshield and positions that may block the solar panel. Do not remove it arbitrarily once installed: The button in the middle of the adhesive is an anti-tamper lever connected to a switch. After installation, the windshield will press the anti-tamper lever in. If the tag is removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. In such cases, you will need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device. Things to note when using ETC: The ETC transaction sensing range is 8 meters. To prevent the ETC device of the car in front from malfunctioning, maintain a distance of at least 10 meters from the car in front to avoid automatic toll payment for the wrong vehicle. The ETC lane recognizes vehicles at a speed of 20 km/h. If the speed is too fast, the vehicle device information may not be read, resulting in failed toll deduction. When using a debit card linked to ETC, insufficient balance will also cause toll deduction to fail.
