What Causes the Unpleasant Odor When Turning on the Car Air Conditioning?

Car air conditioning may emit an unpleasant odor due to prolonged failure to replace the air filter, uncleaned evaporator box, or foreign objects in the ventilation ducts. Failure to Replace the Air Filter: If the filter is not cleaned or replaced for an extended period, it can accumulate significant dust and debris, leading to odor emission. Foreign Objects in Ventilation Ducts: If the car has not been used for some time, small insects or other animals may enter the ventilation ducts. Additionally, if the habit of using the external circulation mode during high-speed driving exists, numerous insects might collide into the ducts. Over time, these foreign objects and dust in the ducts can produce unpleasant smells. Uncleaned Evaporator Box: While most impurities filtered by the evaporator box are expelled through the air conditioning drain pipe, some may mix with condensed water and remain on the evaporator's surface, fostering mold growth and resulting in odors. Solutions for Unpleasant Odor When Using Car Air Conditioning: Check the Air Filter: The car air filter is typically located behind the glove compartment on the passenger side. Some models allow removal of the glove compartment panel by pressing inward, while others may require simple tools. Once the glove compartment is removed, the air filter becomes visible. If the filter appears dirty, replace it by removing the old one and installing the new filter in the same manner. Clean Ventilation Ducts: Turn the air conditioning system to maximum airflow, turn off the AC button, switch to external circulation, and spray air conditioning cleaner directly into the air filter. After spraying the required amount, keep the car doors open and let the system run for a while. Performing this under direct sunlight is recommended, as heat and UV rays provide additional sterilization. Seek Professional Deep Cleaning: If the odor persists, the issue may stem from excessively dirty ventilation ducts or evaporator box, which cannot be resolved with simple cleaning. Since certain areas of the ducts and the evaporator box are difficult to access with standard tools, professional auto repair shops may need specialized equipment like endoscopes for thorough cleaning. Therefore, it is advisable to visit a 4S shop or repair center for comprehensive maintenance to fully resolve the issue.

What should you pay attention to when picking up a new car?

Things to pay attention to when picking up a new car include: 1. Check whether the vehicle identification number (VIN) matches the invoice. The original invoice is required when officially registering the car at the vehicle management office. If the original invoice does not match the VIN, you cannot proceed with the formal license plate selection. Therefore, it is essential to verify the invoice and VIN when picking up the car. 2. Check the car body for scratches. During the process from the factory to the 4S store, new cars may inevitably suffer some scratches. So, when picking up the car, be sure to inspect the four doors of the car, including the roof, etc., carefully for any significant scratches. If there are large scratches, you can request the 4S store to replace the vehicle. 3. Check if the onboard tools are complete. When picking up the car, you should also thoroughly inspect the onboard tools, such as the spare tire, jack, tire-changing tools, and warning triangle. These tools are crucial for daily car use, so make sure they are all in place. 4. Check if the car maintenance manual is complete. The first car maintenance is free and relies on the car maintenance manual. If the manual is missing, you will have to pay for the first maintenance yourself. 5. Check if the invoice and other original documents are complete. After picking up the car, there are two important tasks: paying the purchase tax and registering the car. Paying the purchase tax requires the original tax payment form, while registering the car requires the original invoice, the original certificate of conformity, and the original registration form. All these documents are provided by the 4S store. If any original document is missing, you cannot obtain the official license plate.

Can ETC be used if the card is forgotten to be inserted?

The ETC device cannot be used without the card. According to the "Rules for the Use of Non-Stop Rapid Passage System," the ETC card must be inserted into the OBU device for normal operation; otherwise, user information cannot be read. If the card is removed, you can use the manual lane and have the staff swipe the card. When the ETC card is inserted into the OBU device, there will be a prompt sound, indicating that the device is activated. Without the card inserted, the device remains in a dormant state and cannot recognize vehicle information at toll stations. Therefore, ETC cannot be used if the card is removed. ETC is a non-stop electronic toll collection system, also known as an automatic road toll system. It is a specialized method for toll roads, commonly seen on highways, toll bridges or tunnels, and certain urban road sections to alleviate traffic congestion. ETC Deduction Principle: Highways have one or more ETC lanes. Through microwave short-range communication between the vehicle's electronic tag (installed on the windshield) and the microwave antenna in the ETC lane, the system uses computer networking technology to settle payments with banks, allowing vehicles to pass toll stations without stopping. This is based on the principle of "pass first, deduct later." Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues. Green and eco-friendly: Reduces noise and exhaust emissions by eliminating stops at toll stations. Cost-saving: Reduces vehicle wear and fuel consumption by minimizing frequent starts and stops. Improved efficiency: ETC lanes can theoretically increase passing efficiency by 2-3 times, making traditional ETC faster and more advanced. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will significantly increase." It also set a target of "achieving a 50% ETC usage rate for road passenger vehicles by 2020" in the main indicators of comprehensive transportation development. More future possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, efforts will be made to promote ETC use for trucks and explore deeper integration of ETC systems with smart transportation directions such as vehicle-to-vehicle communication and vehicle-road coordination. This will provide comprehensive travel services for vehicle owners, meaning more application scenarios will support ETC.
