Why Can't the Rear Car Door Be Opened from the Inside?

Car rear doors may fail to open due to reasons such as the child lock being activated, malfunctioning of the door lock cable, or deformation of the door hinge and lock post. Below is an analysis of the reasons why a car's rear door might not open: 1. Child lock is activated: Most vehicle rear doors are equipped with a child lock, marked by a child symbol near the door edge. If accidentally activated and the door is closed, the door will not open. 2. Malfunctioning door lock cable: A faulty cable directly affects the lock mechanism's ability to open. In such cases, replacing the door lock cable is necessary to restore door functionality. 3. Deformation of door hinge or lock post: External force can cause the door hinge or lock post to deform, another common reason for door malfunction. Addressing this issue requires dismantling the door and hinge to replace them with new components, ensuring the door operates normally.

Which areas should not be washed when cleaning a car?

When washing a car, avoid spraying water into the engine compartment, visible electrical component sockets, and the exhaust pipe. Below are some tips for car cleaning: 1. Dust removal: First, lay the seats flat and cover them with a towel or seat cover. Then, use a high-power vacuum cleaner and brushes to clean the interior ceiling extensively, removing surface dust and dirt that can easily fall off. 2. Stubborn stain removal: Spray neutral foam cleaner onto the fabric of the interior ceiling, wait a few minutes, and then use a specialized soft cleaning brush or a well-wrung car-cleaning cloth to repeatedly wipe the area.

Why Do Small Car Brake Pads Get Hot?

Here are the reasons why small car brake pads get hot: 1. Internal reason: The heating of brake pads is due to the work done by the brake pads to overcome friction, which increases the internal energy and temperature of the brake pads. This is a way to change the internal energy of an object through work. The braking process converts the mechanical energy of the moving vehicle into heat energy through friction. 2. External reason: Frequent braking causes the brake pads to heat up due to friction, which reduces the strength, stiffness, and hardness of the brake pads and increases plasticity. At higher temperatures, applying the brakes puts the brake pads under constant stress. Even if the stress is less than the yield point at that temperature, the material will slowly undergo plastic deformation. At normal temperatures, if the stress value is less than the yield strength, the deformation of the material will disappear after the force is removed. Only when the stress value is greater than the yield strength will the material undergo plastic deformation, and the deformation that occurs at this time will not disappear after the force is removed.

Is it mandatory to service new cars at 4S dealerships?

New cars are not required to be serviced at 4S dealerships; they can also be serviced at repair shops. Below is relevant information about car maintenance: 1. Brake fluid maintenance: The maintenance cycle for brake fluid is 2 years or 40,000 kilometers. Brake fluid is fundamental to ensuring the braking system functions properly, so the requirements are quite stringent. Most cars today use DOT4-grade brake fluid. Different grades of brake fluid should not be mixed. 2. Engine oil maintenance: If the car engine is the heart of the car, then engine oil is the lifeblood of the car. Generally, the maintenance interval for most cars is 5,000 kilometers or six months, whichever comes first (e.g., Hyundai, Toyota). Some vehicles have a maintenance interval of 10,000 kilometers or one year, whichever comes first (e.g., BMW, Mercedes-Benz), and others may have intervals of up to 15,000 kilometers (e.g., Peugeot). It is best to refer to the maintenance manual for specific maintenance intervals and durations.

Will non-functioning fog lights affect the annual vehicle inspection?

Non-functioning fog lights will not affect the annual vehicle inspection. This is because fog lights are not checked during the inspection, and some vehicles do not even come equipped with fog lights as they are not a standard feature. Below are detailed methods for defogging your car: 1. Open the windows for air circulation: If the fog inside the car is not too heavy, you can slightly open both side windows to allow air to flow between the inside and outside of the car. This reduces the temperature difference and gradually dissipates the fog. 2. Use the air conditioning system: Using the air conditioning system to defog is the most common method. Almost all cars today have air vents located under the front windshield. Simply adjust the air conditioning to the appropriate setting to blow air and remove the fog. 3. Use a defogging spray: Special defogging sprays are widely available at auto parts stores, supermarkets, and other locations. Spray the defogger onto the inner surface of the car windows and wipe it clean. In addition to removing dirt from the glass, it also forms a protective film that prevents moisture from condensing into fog on the glass.
