Car air conditioning not being cold enough can be caused by: 1. Lack of refrigerant (Freon); 2. Dirty evaporator core; 3. Malfunction in the air conditioning system; 4. Excessive impurities in the refrigerant or refrigeration oil, leading to clogging; 5. Dirty condenser, reducing heat dissipation capacity; 6. Dirty, odorous, or clogged air filter. Methods to check why the car air conditioning is not cold enough include: 1. Checking if the compressor is working properly; 2. Inspecting the refrigerant lines for leaks or damage; 3. Checking the refrigerant level; 4. Cleaning or replacing the air filter. Car air conditioning refers to: The air conditioning device installed in a car, whose functions are: 1.

I've encountered the issue of the air conditioning not being cold enough while driving several times. Usually, insufficient refrigerant is the main cause, possibly due to a leak in the system, which requires inspection and refilling. A dirty filter can also block airflow, and cleaning the air conditioning filter is simple enough to do yourself. A loose or aging compressor belt can affect cooling efficiency. I've also experienced situations where the fan speed was insufficient, leading to poor heat dissipation and ineffective cooling. It's recommended to first check the filter and refrigerant, as regular maintenance can extend the air conditioning's lifespan. If these measures don't resolve the issue, it's best to visit a professional repair shop as soon as possible—safety first. During hot weather, don't wait for problems to arise before taking action.

How to Restore Misadjusted Headlights?

After the headlights are misadjusted, there are two adjustment screws at the rear of the headlight assembly—one for adjusting height and the other for width. You can use these screws to adjust the left-right and height alignment. If the light beam is not concentrated, you need to adjust it horizontally until it reaches the proper height. Here are the detailed steps: 1. Alignment Check: Park the car 10 meters away from a wall. Measure the distances from the low beam to the central axis, from the high beam to the central axis, and from the low beam to the ground. Then, move closer to the wall and mark these measurements on the wall. Observe whether the light beam deviates left or right or is too high or low. If the center of the headlight beam does not align with the marked points, it indicates misalignment. You can adjust it by turning the width adjustment screw until the beam center aligns with the marks on the wall. 2. Standard Adjustment: Note that the headlight width is usually preset at the factory, and self-adjustment is not recommended. If there is a slight deviation, minor adjustments can be made. For example, you can slightly shift the right beam to the right, which can improve visibility of the right-side road during low-visibility conditions like rain or fog. However, it is more advisable to visit a 4S shop or repair shop for professional adjustment.

Is Points Deducted for Making a U-Turn on a Crosswalk?

U-turns are prohibited on crosswalks, otherwise 2 points will be deducted. Below is an introduction to the handling of traffic violations: 1. Timeframe: The vehicle owner needs to go to the local traffic police station to handle the violation within 15 days after receiving the penalty message. If it exceeds 15 days without handling, a late fee of 3% per day will be charged, but the late fee will not exceed double the original fine amount. Early handling can avoid unnecessary penalties. 2. Confirmation method: The fastest and most effective way to know whether you have violated the traffic rules is to inquire about the violation at the vehicle management office or traffic police station. Important documents such as the driver's license, vehicle license, and ID card must be brought, all three of which are indispensable. It is also advisable to prepare some cash, so that even if a violation record is found, the relevant procedures can be processed immediately.
