Why is the cold air from a diesel car's air conditioner not cold?

The reasons why the cold air from a diesel car's air conditioner is not cold are as follows: 1. Too much refrigerant: This leads to a decrease in cooling efficiency. 2. Too little refrigerant: Insufficient refrigerant causes the condenser to become dirty, and a loose compressor drive belt can also result in the air conditioner not cooling properly. 3. Excessive impurities: If there are too many impurities in the refrigerant and the refrigeration oil, minor blockages can occur, leading to insufficient cooling capacity. If there is excessive dirt in the refrigerant and refrigeration oil throughout the entire air conditioning system, it will inevitably clog the filter screen of the filter, reducing the cooling passage capacity and increasing resistance. This also means less refrigerant flows to the expansion valve, resulting in insufficient cooling capacity.

In Subject 4, does the left yield to the right or the right yield to the left?

Right-turning vehicles yield to left-turning vehicles. Below are some rules regarding vehicle yielding: 1. When both vehicles are going straight, yield to the right: At an intersection where both vehicles intend to proceed straight without traffic signals, simultaneous straight movement is highly dangerous. Thus, the 'yield to the right' principle is established, requiring the vehicle to yield to the right-side vehicle going straight. This rule applies not only at intersections but also when vehicles from both sides merge into the same lane, where the right-side vehicle should be allowed to change lanes first. 2. Right-turning vehicles yield to straight-going vehicles: To ensure traffic efficiency, right-turning vehicles must yield to straight-going vehicles. At intersections without traffic signals, both left-turning and right-turning vehicles must yield to straight-going vehicles.

What to Do When the Car Tail Light is Cracked?

If the car tail light is broken, it needs to be replaced immediately. The replacement steps are as follows: 1. Disconnect the power: For safety, always disconnect the power first. Open the car's trunk lid and cut off the vehicle's power to ensure no electrical operation afterward. 2. Remove the dust cover on the back of the tail light: This is a necessary step for tail light replacement. Remove the dust cover to facilitate the replacement process. 3. Perform the replacement: Before replacing the tail light, identify the specific light that needs to be replaced. Press and hold the rotating handle at the back of the light and unscrew it. Then, install the new light, paying attention to the model and color. 4. Reinstall the tail light and dust cover: After installing the new tail light, reattach the dust cover.

What Causes Water Leakage Under the Co-Driver Seat in a Car?

Water leakage under the co-driver seat in a car is likely caused by a door leak. Below are related explanations regarding water leakage under the co-driver seat: Solutions: If you hear obvious water sloshing sounds when opening/closing the door or while driving, it indicates water accumulation inside the door. In this case, simply use a thin wire or small screwdriver to unclog the drainage holes—this can be easily done yourself. Detailed scenarios of leakage: If the window regulator has been replaced, it may be due to improper adhesion of the door waterproof membrane after the replacement, as the membrane needs to be peeled off during the regulator replacement process. If the waterproof membrane is not properly sealed, heavy rain can cause water to enter the cabin. You can either reseal it yourself or replace the waterproof membrane.
