What to Do If the Wuling Hongguang Air Conditioner Is Not Cooling?

The reasons and solutions for the Wuling Hongguang air conditioner not cooling are as follows: 1. Dirty air filter: If the filter is too dirty, it not only causes more impurities to be inhaled into the car, which is harmful to health, but the dirt can also block the air filter, reducing the cooling effect of the air conditioner. It is recommended to replace the air filter every 10,000 kilometers to ensure both the efficiency of the air conditioner and the health of the passengers. 2. Insufficient or leaking refrigerant: Refrigerant, also known as coolant or Freon, is essential for cooling. If the refrigerant is low or insufficient, the cooling effect of the air conditioner will inevitably decline or even stop. This can be easily resolved by refilling the refrigerant at a repair shop. If the air conditioner stops cooling again a few months after refilling (normally, refrigerant should be refilled every 2-3 years), it may indicate a sealing issue in the pipeline, causing the refrigerant to leak too quickly. In this case, professional help from a repair shop is needed. 3. Worn or loose belt: If you hear a 'squeaking' sound when turning on the air conditioner, the lack of cooling might be due to a loose compressor belt. In this situation, the belt of the air conditioner compressor needs to be tightened. Belts, made of rubber, have a limited lifespan and should be replaced if they are too old. 4. Dirty condenser: If the condenser is not cleaned regularly, various impurities can completely cover it, preventing the condenser from dissipating heat properly, which is another reason the air conditioner may not cool effectively.

Can modified LED headlights pass the annual vehicle inspection?

Modifying car headlights to LED is similar to converting to xenon lights, as long as the color temperature, brightness, and beam angle meet the requirements. The annual inspection has the following requirements for lighting: 1. Color temperature: The light color temperature must not exceed 6000K. 2. Brightness: The low beam must not be below 1050 lumens, and the high beam must not be below 1450 lumens. 3. Beam angle: The use of headlights must not affect other road users, and the light height must not be too high. Below are other legal regulations regarding car modifications: 1. The new "Road Traffic Safety Law" clearly stipulates that no unit or individual may assemble a motor vehicle or alter the registered structure, construction, or characteristics of a motor vehicle without authorization. The structure of the vehicle includes the body color, length, width, height (four rigid standards), and the relevant technical parameters of the engine. 2. Before modifying a licensed vehicle, the owner must register and declare the modification to the vehicle management office. The modification technical report must be reviewed and approved by the vehicle management office before the modification can proceed. After the modification is completed, the owner must also complete the modification change procedures at the vehicle management office. 3. Whether a vehicle modification is legal depends on whether the vehicle matches the photo on the vehicle registration certificate and whether it complies with the factory technical parameters. If it does not comply, the vehicle will not pass the annual inspection.

What Causes Jerking Sensation When Braking in an Automatic Transmission?

Here are the detailed reasons: 1. When experiencing jerking while driving, the first step is to determine whether it is caused by an engine malfunction or transmission gear shifting. 2. Jerking caused by an engine malfunction typically occurs when the vehicle is driven at low speeds with steady throttle input, resulting in a surging sensation. Common fault points may include the throttle body, spark plugs, or the vehicle's ignition system. 3. Jerking caused by an automatic transmission malfunction usually manifests as a noticeable impact during gear shifts. While mild jerking during gear changes is normal, severe jerking is abnormal. Common fault points may involve the transmission's shift solenoid valve or control module.

Which wire is the ground wire for the new Polo's taillight?

New Polo taillight ground wire is: The ground wire for the new Polo's taillight is the black wire. Open the taillight circuit board, and the wire that connects to all the bulbs is the ground wire. The ground wire in a car is the negative terminal of the battery connected to the car body, so the entire car is electrified. Electrical devices are installed on the car body, with one end connected to the positive terminal, and the negative terminal is conducted through the car body. The ground wire (negative) is the part connected to the car body. Here is more information: 1. The ground wire in a car refers to a current return line. The power comes out from the positive terminal of the battery, passes through various switches and electrical actuators, and then returns to the negative terminal of the battery through a return wire, forming a cycle that enables the electrical devices to perform various actions and functions. Cars use a single-wire system, meaning most wires carry their own power. 2. The return wires of various electrical actuators do not go directly to the negative terminal of the battery but indirectly return to the negative terminal through the car's own metal body. Any wire connected to the car's metal body can be collectively referred to as a ground wire.
