There are several methods to reduce high pressure in car air conditioning: 1. Excessive refrigerant: Solution: Partially release the refrigerant or recharge it. 2. Excessive compressor oil: Solution: Release all refrigerant, use a machine to extract excess compressor oil, and recharge the refrigerant. 3. Expansion valve or tube opening too small: Solution: Replace the expansion valve or tube, thoroughly clean the air conditioning lines. For systems with a flow controller, replace the flow controller. If the flow controller is on the compressor, replace the compressor. 4. Poor condenser cooling: Solution: Clean surface dirt and lines of the condenser, check the cooling fan (which has high and low-speed settings) for proper high-speed operation. If the condenser is aged and causing poor cooling, replacement is recommended.

How many points are deducted for making a U-turn over double solid lines?

Making a U-turn over solid lines is a traffic violation. According to the "Road Traffic Safety Law," violators will be fined 200 yuan and receive 3 demerit points. Generally, on long roads, white solid lines are present in the middle sections or before intersections. If the lines are yellow dashed or white dashed, U-turns are allowed. However, U-turns are strictly prohibited over any solid lines. Permissible U-turn scenarios: Intersections with U-turn signs allow U-turns: If there is a clear U-turn sign at an intersection, U-turns are permitted. If there is a U-turn traffic light, follow its instructions. If there is no traffic light, proceed with the U-turn only if it does not obstruct other vehicles or pedestrians. Intersections without explicit "No U-turn" or "No Left Turn" signs allow U-turns: If there is no clear prohibition, U-turns are allowed. "No explicit prohibition" means the absence of "No U-turn" or "No Left Turn" signs and no solid lines in the middle of the road. Yellow grid lines also permit U-turns: Yellow grid lines are no-parking zones typically marked at intersections prone to congestion due to temporary stops, important facility entrances, or other designated areas. Stopping on these lines (including waiting for traffic lights) is a violation. Although parking is prohibited in yellow grid zones, U-turns are allowed as long as there are no central barriers. Yellow grid lines without barriers are equivalent to "U-turn permitted." Intersections with U-turn traffic lights: This is straightforward—if there is a U-turn traffic light, follow it. U-turns are allowed only on green. When "No Left Turn" and "U-turn permitted" signs coexist: U-turns are allowed, but left turns are prohibited. Note that "No U-turn" is not the same as "No Left Turn." Precautions when making U-turns at intersections: Check road markings—if they are solid lines, U-turns are prohibited under any circumstances. Continue driving to find a suitable spot. If there is a "No Left Turn" sign, even without a "No U-turn" sign, U-turns are not allowed at that intersection because U-turns inherently involve left-turning movements. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, U-turns are not permitted at that intersection. Always yield to oncoming traffic when making a U-turn. Proceed only if it does not interfere with straight-moving vehicles, or you will bear full responsibility for any accidents. Near intersection stop lines, lanes often have guiding arrows. The leftmost lane may not always have a left-turn arrow—some may have straight arrows. Even without explicit "No U-turn" signs, U-turns are prohibited in such lanes. U-turns must not be made on crosswalks, as this is also a traffic violation.

Solutions for Volkswagen Lavida's Air Conditioning Not Cooling?

There are mainly three solutions for Volkswagen Lavida's air conditioning not cooling, which are: First method: Refill the refrigerant. Second method: Flush the condenser. Third method: Clean or replace the air conditioning filter. Below are the main reasons for Volkswagen Lavida's air conditioning not cooling: 1. Insufficient refrigerant in the air conditioning system pipeline leads to inadequate refrigerant volume, reduced pressure, and diminished heat absorption, resulting in poor cooling performance. 2. A dirty condenser can also cause poor cooling effect. 3. Check the air conditioning filter. If the car hasn't been maintained for a long time, the filter might be too dirty, affecting the air conditioning cooling performance.

Where is the oil check valve located on the Chevrolet Cruze?

The location of the oil check valve varies among different car brands. For the Chevrolet Cruze, the oil check valve is situated behind the car's alternator, on the oil passage leading from the oil filter to the cylinder head, and is mostly found on the oil filter base. Additional information about the Chevrolet Cruze is as follows: 1. Repairing the oil check valve on the Chevrolet Cruze is relatively troublesome, as it first requires the removal of the alternator. 2. The oil check valve is a device in the car's hydraulic system that prevents the reverse flow of oil and can be divided into straight-through check valves and right-angle check valves.

Where is the rearview mirror heating switch on the Buick Verano?

The rearview mirror heating switch on the Buick Verano is located directly above the air conditioning fan speed knob. This switch is labeled "rear." Turning it on activates the heating function for both the upper and lower rearview mirrors as well as the rear window. A yellow light indicates that the heating is on, while the light turning off means the heating is deactivated. The heating function will automatically turn off after a period of use. Rearview mirror heating is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the surface, gradually removing rain or fog, eliminating the need for the driver to frequently wipe the mirrors manually, thereby reducing driving hazards. How to use the rearview mirror heating function: There are generally two ways to activate the rearview mirror heating function. One is combined with the electric rearview mirror adjustment knob—simply rotate the knob to turn it on. The other is located on the air conditioning control panel—pressing the heating button activates the function. No manual angle adjustment is required, as the driver's side has a dedicated adjustment button. Principle of the rearview mirror heating function: After pressing the button, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature within minutes, typically between 35-60 degrees Celsius. The heat is distributed across the left and right rearview mirrors. As the temperature rises and evaporation occurs, water droplets on the mirror surface gradually shrink, and fog slowly dissipates, effectively defrosting and defogging the mirror. However, if the rain is particularly heavy, the effect may diminish and become less noticeable. Precautions for using the rearview mirror heating function: The principle of rearview mirror heating involves electric heating wires embedded in the mirror. These wires consume a significant amount of power. When using this function, ensure the car is running. Avoid activating rearview mirror heating while the vehicle is stationary to prevent draining the car battery, which could lead to insufficient power for starting the engine. Other methods for defogging rearview mirrors include: Opening windows slightly to create air convection between the inside and outside of the car, reducing the temperature difference and gradually eliminating fog. Adjusting the car's air conditioning to the appropriate setting to blow warm air for defogging.
