How to Solve Fogging on Side Windows in Rainy Weather?

In rainy weather, fogging on the side windows can be addressed using toothpaste, water repellent, or air conditioning defogging. Here are specific solutions to the fogging issue: On rainy days, evenly apply toothpaste or soap to the car's side window glass. Wait for a while until the applied soap hardens, then wipe it clean with a towel. A wax layer will form on the glass surface, which has excellent water-repellent properties and can effectively prevent fogging or water droplets on the rearview mirror from causing blurred vision. Purchase a specialized water repellent and evenly spray or apply it to the rearview mirror. A protective film will form on the rearview mirror's surface, which also has excellent hydrophobic properties, effectively preventing fogging or water droplets on the rearview mirror and ensuring clear visibility. Turn on the car's air conditioning to cold air and adjust the vents to the front windshield to quickly clear fogging on the glass. If you want to completely eliminate fogging, you can turn on the air conditioning to hot air before starting the car and blow it directly onto the front windshield for 3 minutes. This can fundamentally prevent glass fogging. Air conditioning cooling can also dehumidify and achieve the fastest defogging effect. The driver can turn on the air conditioning's cooling mode and adjust the blowing mode to the windshield setting. In about ten seconds, the fog can disappear.

What Does the Old Car Replacement Subsidy Mean?

Old car replacement subsidy refers to the cash compensation provided to car owners who replace their used cars before purchasing new ones. This subsidy is primarily designed to encourage the recycling of used vehicles, phase out older models, and achieve economic and environmental goals. Below are the specific steps for the replacement subsidy process: 1. Transfer the old car out of the city or send it to a qualified dismantling facility for scrapping. 2. Check relevant information through designated service points or platform information systems and select the reward models listed on the transaction platform. 3. Fill out and submit the application form via the platform information system (or at a service point). The transaction platform will review the owner's information, and after supervision and approval by relevant government departments, the platform will notify the owner of the review results. 4. Approved owners can either print the enterprise reward voucher corresponding to the intended new vehicle from the platform information system or collect it at a service point. 5. The owner presents the enterprise reward voucher to the car dealership to purchase a new vehicle. 6. The dealership uploads the new car purchase information to the transaction platform. 7. The owner submits materials related to the old car elimination and new car replacement at a service point to apply for the government subsidy. After approval, the government subsidy will be transferred to the owner's bank account within N working days.

How to Install Front Car Radar?

The installation method for front car radar: 1. First, mark the installation positions of the four sensors on the front bumper, apply black electrical tape, and then drill holes using the provided drill bit. 2. Remove the plastic cover above the grille, use a wire tool (such as an iron wire) to pull the sensor signal wires into the engine compartment, connect the sensors, and organize the wiring harness. 3. Remove the cover above the accelerator pedal, guide the signal wires of the four sensors from the front of the car into the cabin. Install the radar display near the A-pillar and tuck the wires into the interior seams. 4. Open the glove box cover on the passenger side, locate the ACC fuse interface (can be identified using a test pen), and connect the red wire. 5. Route the red ACC power wire from under the dashboard to the main driver's cabin and connect it to the pink wire of the main unit plug. Connect the black wire to the ground. Locate the brake light wire in the main wiring harness (use a test pen to identify; it lights up when the brake is pressed and turns off when released), and connect it to the white wire of the main unit plug. 6. Plug the connectors of the four sensor signal wires, power wires, and display wires into the main unit, then start the car for debugging. Since the four sensor signal wires are not labeled, each sensor needs to be tested individually to determine the correct order, and the connectors should be reinserted accordingly. 7. After debugging, secure the main unit, restore the interior, and complete the installation.

How to Read an Automotive Air Conditioning Refrigerant Gauge?

Automotive air conditioning refrigerant gauges display pressure readings, which indicate the compressor's discharge pressure (high pressure) and suction pressure (low pressure). These readings help determine whether the system is functioning properly, such as identifying issues like blockages or refrigerant leaks. The gauge typically shows MPa (megapascals) and bar, which are commonly used pressure units in China. 0.1MPa = 1bar = 1 kg/cm². Taking the commonly used R22 refrigerant as an example, under normal operating conditions of the refrigeration system, the low pressure generally ranges between 3-6 bar, and the high pressure between 10-25 bar, depending on the ambient temperature. Precautions for Adding Refrigerant: When adding refrigerant to the air conditioning system, it is crucial to ensure that the piping system has expelled any excess air, moisture, or blockages. After prolonged use, the air conditioning system requires periodic replenishment of Freon. Typically, this task is entrusted to professionals, as they know where to source Freon and the correct method of adding it to the system. If your home air conditioning system has been installed for about five to six years, it is necessary to check the Freon levels. When adding Freon, it is important to add the correct amount. More Freon is not necessarily better; the right amount is crucial. Excessive Freon can impair the system's performance, leading to poor cooling or even a complete lack of cooling.
