The reasons for abnormal noise in the air conditioner are as follows: 1. During the rotation of the air conditioner, the electromagnetic clutch will experience necessary wear, resulting in noise when using the air conditioner. In this case, replacing the pump head immediately will suffice, as damage to the compressor's bearings can affect the air conditioner's operation. 2. The air conditioner's compressor may have a malfunction. As a high-speed rotating component, the compressor has a relatively high probability of developing issues. 3. The electromagnetic clutch inside the compressor is damaged, or the internal components of the compressor are severely worn. This condition can affect the compressor, especially when the vehicle's generator has insufficient power supply, the air conditioning system's pressure is too high, or the engine is overloaded.

What Are the Common Knowledge of Traffic Rules?

Here is an introduction to the common knowledge of traffic rules for driving tests: Common Knowledge 1: Pedestrians should cross the road using pedestrian crossings; stop at red lights, proceed at green lights, and yellow lights indicate a warning. When the yellow light is on, vehicles and pedestrians are not allowed to proceed, except for vehicles that have already crossed the stop line and pedestrians who have entered the crosswalk, who may continue. When the yellow light is flashing, vehicles and pedestrians must proceed under the principle of ensuring safety. Common Knowledge 2: According to road division, generally, motor vehicles, non-motor vehicles, and pedestrians should travel in their respective lanes. Where there is no division of motor vehicle lanes, non-motor vehicle lanes, or pedestrian walkways, motor vehicles should travel in the middle of the road, while non-motor vehicles and pedestrians should travel on both sides of the road. Common Knowledge 3: Dedicated lanes are set up on roads, allowing only specified vehicles to pass. Other vehicles are not permitted to enter these dedicated lanes without authorization. Common Knowledge 4: Both the driver and passengers of a motorcycle must wear safety helmets as required.

How to Shift Gears Smoothly Without Grinding in FAW J6?

The shifting technique for FAW J6 is to shift gears timely, correctly, smoothly, and quickly. When starting the vehicle, it is generally recommended to use a low gear. Once road conditions permit, promptly shift up to higher gears in sequence. Higher gears are generally more fuel-efficient than lower ones, so it's important to upshift promptly after starting and avoid driving in a gear that's too low for the speed. More details about vehicle gears are as follows: 1. Introduction One: Generally, it is not allowed to forcibly shift into a lower gear when the vehicle is at a high speed. This should only be done in very special circumstances or when the vehicle's brakes suddenly fail and engine braking is necessary. 2. Introduction Two: First gear is used for normal starts or climbing very steep hills, with speeds typically around 10 km/h. Second gear is used for accelerating after starting or for low-speed driving, with speeds typically around 20 km/h. Third gear is used for speeds between 20-40 km/h and is commonly used for city driving. 3. Introduction Three: To engage first gear, move the gear lever to the left and then push forward. For second gear, move the lever to the left and then push down. For third gear, push the lever straight up from the neutral position. For fourth gear, push the lever straight down from the neutral position. For fifth gear, push the lever to the right and then straight up.

What materials are needed for a driver's license replacement and how long does it take?

To replace a driver's license, the original and photocopy of the motor vehicle driver's identity document must be provided. Below are some important notes regarding driver's license replacement: Do not drive during the interim period: If replacing a damaged license, the driver must not operate a motor vehicle with the original license during the interim period before receiving the new one, as this will be considered driving without a license. The original license becomes invalid: After obtaining a replacement license, the original motor vehicle driver's license becomes void. Other documents: Besides loss or damage, another reason for replacement could be the expiration of the license. In this case, the original and photocopy of the physical condition certificate must also be submitted.

Which Lane is the Deceleration Lane on the Highway?

On highways, there are generally three lanes: the left lane is the overtaking lane, the middle lane is the travel lane, and the right lane is the deceleration lane. In the case of four lanes, the left lane is the overtaking lane, the middle two lanes are travel lanes, and the fourth lane is the deceleration lane (or emergency stopping lane). Additional information: Article 78 of the Implementation Regulations of the Road Traffic Safety Law stipulates: 1. Regulation 1: Highways shall indicate the speed limits for each lane, with the maximum speed not exceeding 120 km/h and the minimum speed not less than 60 km/h. 2. Regulation 2: On highways, the maximum speed for small passenger vehicles shall not exceed 120 km/h, for other motor vehicles not exceeding 100 km/h, and for motorcycles not exceeding 80 km/h. 3. Regulation 3: For roads with two lanes in the same direction, the minimum speed for the left lane is 100 km/h; for roads with three or more lanes in the same direction, the minimum speed for the leftmost lane is 110 km/h, and for the middle lane, it is 90 km/h. 4. Regulation 4: If the speed limit indicated by road signs is inconsistent with the above lane speed regulations, drivers shall follow the speed limit indicated by the road signs.
