Car air conditioning's internal and external circulation modes can be switched by pressing the circulation mode button on the control panel. Use internal circulation mode when driving in congested urban roads, and switch to external circulation mode for long-distance or highway driving. Car air conditioning refers to the air conditioning device installed in vehicles, which can cool, heat, ventilate and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue and improving driving safety. The car air conditioning system mainly consists of compressor, electronically controlled clutch, condenser, evaporator, expansion valve, receiver-drier, pipelines, condenser fan, vacuum solenoid valve, idle speed controller and control system.

Reasons for the adblue light: adblue refers to automotive urea, vehicle urea, or automotive environmental urea, which is generally made from water and urea. It can effectively reduce the nitrogen oxide content in vehicle exhaust and lower air pollution caused by NOx. When the adblue light is on, it indicates a shortage of automotive urea fluid, and it needs to be replenished. The adblue light serves as a reminder for the car owner to add diesel exhaust fluid. 2. The role of automotive urea: Automotive urea is a necessary consumable in SCR technology, composed of 32.5% high-purity urea and 67.5% deionized water. adblue can effectively reduce the nitrogen oxide content in vehicle exhaust and lower air pollution caused by NOx.

What is the difference between application in progress and acceptance in progress?

Application in progress and acceptance in progress have the following differences: 1. Application in progress: This means the application has not yet been scheduled. Generally, the review time for scheduling the third subject (road test) takes 5-10 days. If you are in a first-tier city where there are many applicants, the time may be extended, and you will be notified at the latest 3-5 days before the exam. 2. Acceptance in progress: This indicates that the application has been scheduled and is under review, awaiting results. A successful scheduling will be notified via SMS. If you receive the SMS, you can take the test on the same day. Additionally, you can directly call the local vehicle management office to confirm whether the test has been successfully scheduled.

Why does the brake light keep burning out?

Brake lights frequently burning out is primarily caused by burrs left on the circuit board during manufacturing that weren't properly cleaned. These imperfect contact points generate heat and deform when current continuously passes through, increasing the contact area until it's large enough to pass sufficient current to blow the fuse. Below is an expanded explanation: 1. Brake light overview: Brake light switches vary by vehicle model and typically function by completing/interrupting circuits to send electrical signals that activate related systems or control power to the brake lights. 2. Symptoms of faulty brake lights: A damaged brake light switch may cause symptoms like constantly illuminated lights, non-functioning lights, or intermittent operation. In severe cases, the vehicle's computer may mistakenly interpret braking when none is occurring, leading to increased fuel consumption and cruise control failure.
