No, the air conditioner cannot cool without starting the car. Below is an explanation regarding the situation when the car air conditioner fails to cool: 1. Compressor operation status: Check if the drive belt is broken or loose. If the drive belt is too loose, it will slip, accelerate wear, and fail to transmit power. Also, check for noise inside the compressor and whether the compressor clutch is slipping. 2. Condenser and fan status: Check if the condenser fins are covered with dust. If the condenser fins are covered with dust, the condenser's efficiency will be greatly reduced. Also, ensure the condenser fan is operating properly. 3. Refrigerant level check: If you see a large number of bubbles through the sight glass, it indicates insufficient refrigerant. If you pour water on the condenser to cool it and still see no foam in the sight window, it indicates excessive refrigerant. Check for oil stains at the connections and seams of each device. Oil stains at the connections or seams indicate refrigerant leakage, and the relevant parts should be tightened or replaced.

Will modifying the central control wiring affect the warranty if issues arise?

Modifying the central control wiring should affect the warranty. This situation will definitely impact future warranty claims because modifying the central control inevitably involves altering related wiring. Therefore, the 4S dealership may refuse to honor the warranty on the grounds of this modification. Below is additional information: 1. Overview of the vehicle warranty: The vehicle warranty means that various components will be replaced free of charge if they are confirmed to be damaged due to quality issues rather than human factors, such as issues with the speedometer or air conditioning. The warranty period or mileage for the vehicle comes from the manufacturer's publicly announced data. Generally, it is two years or 60,000 kilometers, though some manufacturers may offer warranty mechanisms that exceed these terms. 2. Contents of the vehicle warranty: Whether domestically or internationally, the vehicle warranty does not actually mean that every component of the vehicle enjoys the same warranty service. Instead, warranties are provided on a component-by-component basis. Typically, components prone to damage or wear, such as batteries, shock absorbers, wipers, rubber parts, and audio equipment, have shorter warranty periods, while components less prone to damage, such as engine blocks, have longer warranty periods. Some manufacturers may also declare certain components, like tires, as non-warranty items. Different components have different warranty periods, so the so-called vehicle warranty period is more accurately described as the warranty period for "the component with the longest warranty period in the vehicle." Some manufacturers' extended warranties may only apply to a few very durable components, and uninformed consumers often mistakenly believe this means the entire vehicle has an extended warranty.

What are the common failure symptoms of oxygen sensors?

Common failure symptoms of oxygen sensors include: 1. Oxygen sensor poisoning; 2. Carbon deposits forming on the oxygen sensor surface; 3. Ceramic cracking of the oxygen sensor; 4. Burnout of the heater resistance wire; 5. Internal wiring disconnection of the oxygen sensor. The oxygen sensor is installed in the exhaust pipe to detect the oxygen concentration in the exhaust, sending feedback signals to the ECU, which then adjusts the fuel injection volume of the injector to maintain the air-fuel ratio of the mixture near the theoretical value. Cleaning method for oxygen sensors: 1. Remove the oxygen sensor and use a 5% to 10% ferric chloride solution with excess hydrochloric acid; 2. Soak the oxygen sensor in the solution for 10 to 15 minutes before removing it; 3. Rinse with water to ensure the four holes are clear and the internal carrier appears white.
