Failure is mainly caused by prolonged use of the blower and excessive dust accumulation. Here is an introduction to the blower: The function of the blower: It blows the cold air from the air conditioning evaporator or the hot air from the heater core into the car to maintain a balanced temperature inside the vehicle. Classification of blowers: Blowers can be divided into: Roots blowers, blast furnace blowers, magnetic levitation blowers, single-stage high-speed centrifugal blowers, multi-stage centrifugal blowers, and air suspension centrifugal blowers. The blower consists of a motor, air filter, blower body, air chamber, base, and oil drip nozzle.

I still remember how annoying it was when my Mercedes blower regulator failed last time. That day, the car's AC suddenly stopped working, only blowing a tiny bit of air—it was unbearably hot inside. Initial inspection revealed that the aging internal circuitry of the regulator module caused switching failures. Mercedes' premium AC system has high environmental requirements; moisture or dust intrusion can corrode components. After replacing it with an OEM regulator, I realized the cost of neglecting maintenance. Regularly cleaning the AC intake vents and filters to prevent moisture buildup can avoid such failures. If the airflow becomes unstable or makes unusual noises, timely professional inspection is crucial—don’t wait until it completely fails and affects driving comfort. Mercedes repair costs aren’t cheap, but investing in maintenance is more cost-effective.

What is the Assurance tire?

Assurance is a tread pattern series under the Goodyear tire brand, known as 'Anshu Wheel' in Chinese. Below are the relevant details: 1. Classification of Goodyear tires: Goodyear prioritizes safety as its primary pursuit. Its passenger car tires are mainly divided into the Assurance series, Eagle series, Optilife, Excellent TriMax, and Duraplus. 2. Characteristics of Goodyear tires: Goodyear tires are relatively more wear-resistant, hence the tire body is harder, with strong grip and handling performance. They focus on high-end tires, mainly supporting mid-range products of top-tier car brands such as the BMW 5 Series, Mercedes-Benz E-Class, and C-Class. 3. The Assurance series primarily includes three tread patterns: Assurance-Fuel-Max (Anjie), Assurance (Anshu), and Assurance-Triple-Max (Ancheng). Later, Assurance-duraolus2 (Jiucheng) and Assurance-Triple-Max2 (Yicheng) series were developed. These series patterns utilize special ArmorGrip technology, incorporating DuPont Kevlar material, with fuel efficiency and safety as their main performance features.

What does 'folder' mean in a car?

In cars, 'folder' refers to a directory where you can switch between different folders. Some models display it as 'tunefolder', which translates to 'audio folder'. The function of this button is: when more than two song folders are created, pressing the FOLDER down button will automatically jump to the second folder. Here is an introduction to related car buttons: 1. A-OFF: This button turns off the engine auto start-stop function. It should be used in congested areas or waterlogged sections to ensure normal engine output. 2. AUTOHOLD: The auto-hold button, usually located next to the electronic handbrake. When encountering traffic lights or temporary stops, using this button will temporarily auto-stop the engine. Similar to the auto start-stop function, its advantage is that you can release your right foot directly in D gear, especially useful on slopes. To start, lightly press the accelerator, and the parking system will automatically disengage. 3. DUAL-DUAL: The air conditioning zone control button. Pressing this button lights up the indicator, allowing you to set the air conditioning temperature for the driver and passenger areas separately. After adjusting to the desired temperature, turn off this button, and the automatic air conditioning will regulate the temperature according to the set values.

Can the in-car camera monitor the interior situation?

In-car cameras can monitor the interior situation. Below is relevant information about automotive cameras: Cameras: Omnidirectional cameras are equipped with both a camera and a reflector at the top of corner poles. A hemispherical reflector is installed facing downward at the top of the corner pole, and the camera captures images reflected from below upwards. By transmitting the captured images to a screen, it provides a 360-degree view of the vehicle's surroundings at heights lower than the corner pole. Clarity: Clarity is one of the key metrics for evaluating cameras. Generally, products with higher clarity yield better image quality. Cameras with 420-line resolution have become mainstream for rearview cameras, while 380-line models can also be viable if properly adjusted. However, due to variations in chip grades, differences in photosensitive components, and the varying skill levels of technicians, products with the same chip and grade may exhibit different quality effects. Conversely, products with higher clarity often experience some compromise in night vision performance.

What is the handle above the car called?

The handles above the driver's seat and front passenger seat are called roof front handles (left) and roof front handles (right) respectively. Here are the functions of other commonly used features in the car: Multi-function steering wheel: The main function of the multi-function steering wheel is to control phone calls, switch music, activate cruise control and other functions without having to look at the central DVD. The round button in the center of the DVD on the central control panel is the DVD switch, which can turn the DVD on and off. Display screen: The display screen in the instrument panel can show whether the car doors are open, the tire pressure of the four tires, set the time, adjust maintenance information, set the vehicle speed limit and other functions. The USB port on the central control panel supports music playback in MP3 format. The car power socket on the right can be used to charge other external power supplies.

Why is the clutch pedal heavy?

There are several reasons why a car's clutch pedal may feel heavy: 1. Excessive return spring tension: To ensure the clutch pedal returns quickly and accurately to its ready position when released, a return spring is installed. If the heavy pedal sensation occurs after replacing the spring, it's likely due to excessive tension in the clutch pedal return spring. 2. Damaged clutch slave cylinder: Many vehicle clutches use a power-assisted system that normally makes operation easier. However, if the clutch slave cylinder fails, it may result in insufficient assistance, ultimately making the clutch pedal feel very heavy when pressed. 3. Low compressed air pressure: Most of the power driving the clutch booster comes from compressed air in the air reservoir. If the compressed air pressure to the booster is too low, it will cause insufficient assistance. Therefore, when such a fault occurs, the compressed air pressure to the clutch booster should be checked first. 4. Insufficient lubrication: The clutch is actuated by the slave cylinder (commonly called the release cylinder) through a series of mechanical structures to disengage the pressure plate. There are several points in this structure that require lubrication. If lubrication is insufficient, excessive friction can cause the clutch pedal to feel heavy. 5. Overly tight release bearing: If the clearance between the release bearing and the guide sleeve is too small, it will cause excessive friction. The driving force is wasted on the friction between the release bearing and guide sleeve, inevitably making the pedal feel heavy.

Can the car start if it hasn't been flooded?

If the water level is not deep, the engine can start. If the engine is flooded, it won't start. Here is relevant information about ignition: Traditional ignition: The working process of a mechanical ignition system involves the crankshaft driving the distributor shaft to rotate. The cam on the distributor shaft rotates, causing the primary contacts of the ignition coil to connect and disconnect, thereby generating high voltage. This high-voltage ignition current is then distributed to the spark plugs of each cylinder in the required sequence via the rotor on the distributor shaft. The spark plugs emit sparks to ignite the gas in the combustion chamber. Electronic ignition: The electronic ignition system is completely different from the mechanical ignition system. It includes an electronic control device for ignition, which contains ignition control maps (MAP) for various engine operating conditions. A series of sensors, such as the engine speed sensor, intake manifold vacuum sensor (engine load sensor), throttle position sensor, and crankshaft position sensor, are used to determine the engine's operating state.
