The reasons why the BMW 525 air conditioning is not cooling are as follows: 1. Refrigerant issue: Sometimes, the reason for the car air conditioning not cooling is a problem with the refrigerant in the car's air conditioning system. 2. Filter blockage: Sometimes, excessive impurities in the refrigerant and refrigeration oil of the car air conditioning can also cause the filter screen to become blocked, reducing the cooling effect, increasing resistance, and decreasing the flow of refrigerant to the expansion valve, leading to the car air conditioning not cooling. 3. Saturated dryer tank: There is a dryer tank in the car air conditioning refrigeration system, whose main task is to absorb moisture in the refrigerant and prevent excessive moisture in the refrigerant from reducing the cooling capacity. When the desiccant in the dryer tank is saturated, moisture can no longer be filtered out. 4. Compressor drive belt too loose: Sometimes, the car air conditioning does not cool because the compressor's drive belt is too loose, or it may be due to a decrease in the condenser's heat dissipation capacity, leading to a reduction in the air conditioning cooling capacity.

What is the function of an automotive power distribution box?

The function of an automotive power distribution box is to facilitate assembly and troubleshooting during repairs. The automotive power distribution box is essentially the car's fuse box, which is located in different positions depending on the vehicle. Different electrical loads such as ignition circuits, headlights, parking lights, horns, and air conditioning use fuses of different colors and specifications for distinction. The reasons for blown fuses in the automotive power distribution box include: 1. Installation of higher-wattage car bulbs; 2. Addition of a multi-way adapter to the car's cigarette lighter socket, leading to simultaneous use of multiple auxiliary devices; 3. Excessive installation of electrical equipment, with poorly insulated wiring causing oxidation at the connections; 4. Direct rinsing of the engine compartment with tap water causing short circuits; 5. Aging wire insulation and exposed metal wires leading to short circuits; 6. Incorrectly connecting a high-power dual-cylinder electric air pump to the cigarette lighter socket for use.

Which lane to take at the highway entrance?

At the highway entrance, take the right lane and turn on the left turn signal. Direction indicator signs are set up on ordinary roads connected to highway ramps to guide vehicles entering the highway; in addition to entrance distance warning signs, there are also entrance direction warning signs, entrance warning signs, direction warning signs, and main intersection signs. Entrance distance warning signs are placed 1km and 500m away from the highway intersection; some may also have axle weight restriction signs, placed 200m away from the highway intersection; entrance direction warning signs are set up at the highway intersection; entrance warning signs are placed near the starting point of the highway acceleration lane. The ramp is part of the highway. Driving in the wrong direction or making a U-turn on the highway, according to the "Road Traffic Safety Law Implementation Regulations" and related regulations, will result in a 12-point penalty. Stopping, making U-turns, reversing, or driving in the wrong direction on the highway can lead to unimaginable consequences in the event of an accident. Therefore, driving in the wrong direction on the highway is prohibited, and failure to comply will result in corresponding penalties.

Is it allowed to exceed the speed limit on highways?

Exceeding the speed limit on highways is not allowed. According to traffic laws, vehicles exceeding the speed limit by less than 10% will not be penalized; exceeding by 10% to less than 20% will result in a fine and 3 penalty points; exceeding by 20% to less than 30% will result in a fine and 6 penalty points, etc. Speed limits vary for different sections of the highway, with the maximum speed limit being 120 kilometers per hour. Additionally, drivers must adhere to the speed limit signs posted on the actual road. In adverse weather conditions such as snow, ice, rain, or fog, where the road surface is slippery and visibility is poor, drivers should reduce their speed, increase the following distance, avoid unnecessary lane changes, and drive with caution. If feeling slightly fatigued, they should immediately proceed to the nearest service area or exit the highway to rest. Night driving poses additional challenges due to poor visibility, requiring heightened concentration. In low-temperature or snowy conditions, drivers should reduce speed to guard against black ice, maintain a safe following distance of at least 100 meters from other vehicles, continuously monitor the road ahead, and make timely and correct judgments.

Can Motorcycles Ride on Highways?

Motorcycles are allowed on highways, but not all cities permit motorcycles to travel on highways. It depends on local regulations. If the local area does not allow motorcycles on highways, motorcycles are not permitted to force their way onto the highway. Once such behavior occurs, the motorcycle will be blacklisted. When riding on highways, the maximum speed for motorcycles cannot exceed 80km/h, and the minimum speed cannot be lower than 60km/h. Within this speed range, there is only a fluctuation of 20km/h, making it easy to exceed the speed limit or fall below the minimum speed requirement if not careful. Driving a motorcycle requires complete documentation and full equipment. To ride a motorcycle on the highway, you must carry your driver's license, vehicle registration, helmet, etc. Additionally, passengers are not allowed on the back seat of the motorcycle. Riding on the highway without even the most basic helmet is extremely dangerous. Therefore, full gear is essential when riding on highways. Moreover, always prioritize safety when riding on highways—avoid the fast lane, stick to the rightmost lane, and refrain from reckless overtaking.

What is the minimum speed limit on highways?

Highways have a minimum speed limit of 60 km/h. Different lanes on highways have varying speed limits: for two lanes in the same direction, the left lane has a minimum speed of 100 km/h while the right lane maintains 60 km/h; for three lanes in the same direction, the far-left lane requires a minimum of 110 km/h, the middle lane 90 km/h, and the far-right lane 60 km/h. Notably, driving below 60 km/h will result in a 3-point penalty. Contrary to popular belief, driving too slowly on highways isn't necessarily safer. When multiple vehicles travel at low speeds, overall traffic flow slows down. Therefore, establishing minimum speed limits helps minimize speed differentials between vehicles, encouraging consistent speeds among consecutive cars. This reduces unnecessary lane changes and overtaking, ultimately decreasing accident risks. The minimum speed regulation ensures smooth and safe highway operations. Drivers must strictly adhere to lane discipline on highways. Expressways are divided into bidirectional configurations with 4, 6, or 8 lanes. Motorists must maintain their designated lanes without crossing dividing lines or making unauthorized lane changes, and should never straddle lane markings.

What Needs to Be Checked Before Driving on the Highway?

Before driving on the highway, you need to check the vehicle's exterior, fluid safety, "four pressures" safety, and the braking system. A comprehensive inspection of the vehicle is necessary to ensure it is in good condition and can safely reach the destination. Check the vehicle's exterior: Observe whether the vehicle's lights and various signal lights are functioning properly. On the highway, lights are crucial as they serve as a means of communication between vehicles on the road. "Five fluids" safety check: The five fluids refer to engine oil, transmission oil, power steering oil, brake fluid, and fuel. "Four pressures" safety check: The four pressures refer to oil pressure, voltage, tire pressure, and air pressure. Braking system check: If the thickness is found to be close to or less than the minimum thickness specified by the manufacturer, it should be replaced immediately. While checking the brake pads, also inspect the wear on the brake discs or brake drums. If dents appear on the contact surface, resurfacing ("glazing") of the disc or drum is necessary to ensure proper contact area with the brake pads and improve braking force.
