Common reasons for the Mercedes-Benz car air conditioner not blowing air include blower motor failure and cabin air filter failure. Below is an analysis of the causes: 1. Blower motor failure: As the core component determining whether the air conditioner blows air, if the blower motor fails, it will definitely stop blowing air. Possible causes of blower motor failure include overheating damage to internal coils or capacitor failure. Owners can check for faults by turning the air conditioner's fan speed and air volume to maximum and listening for the blower motor's sound. 2. Cabin air filter failure: Clogging of the cabin air filter is the most common situation causing the air conditioner to stop blowing air. Outside air passes through the cabin air filter before entering the vehicle interior, during which it also traps many airborne particles, making it prone to clogging. The cabin air filter can be removed for inspection. If not excessively dirty, cleaning the debris with an air gun and reinstalling it may help check the air vent issue.

How to Check Tire Pressure Monitoring in the Car?

Tire pressure monitoring is displayed on the trip computer or the central control screen, appearing in the corresponding position each time the vehicle is powered on. The pressure sensors of the tire pressure monitoring system are installed inside or outside the tires, transmitting signals to the receiver, which then directly provides the tire pressure values on the in-car display. Below is an introduction to tire pressure monitoring in the car: 1. Indirect Tire Pressure Monitoring System: This is a simpler tire pressure monitoring system that utilizes the existing ABS sensing function to compare the rotation counts of the tires. 2. Direct Tire Pressure Monitoring System: This system uses pressure sensors installed in each tire to directly measure the tire pressure, transmitting the pressure information from inside the tire to a central receiver module via wireless transmitters, then displaying the tire pressure data for each tire. When the tire pressure is too low or there is a leak, the system will automatically issue an alert.

Is it better to register the car by yourself or let the 4S shop do it?

It is better to register the car by yourself. There are mainly the following situations for car registration: 1. Registering at the 4S shop: The 4S shop needs to arrange special personnel to register the car, and these services are not free, they all require costs. So while enjoying the convenience, you need to pay enough fees. Entrusting the 4S shop to handle the new car registration, you only need to submit the required documents to the 4S shop, and basically don’t have to worry about anything else, just wait quietly for the satisfactory result. 2. Registering by yourself: If you go to the vehicle management office to register by yourself, you have more freedom in choosing the license plate number, and you may choose a license plate number that you like more.
