Can Cars Be Modified?

Cars can be modified, but it should be noted that no unit or individual is allowed to assemble motor vehicles or arbitrarily alter the registered structure, construction, or characteristics of a motor vehicle, including changing the vehicle model, engine number, frame number, or vehicle identification code. Installing windshields, water tanks, toolboxes, spare tire racks, front and rear anti-collision devices, or adding interior decorations to a motor vehicle requires applying for modification registration. According to motor vehicle registration regulations: If the modifications do not affect safety or the identification of the license plate, the owner does not need to apply for modification registration. Examples include small and micro passenger cars adding front and rear anti-collision devices, or freight vehicles installing windshields, water tanks, toolboxes, spare tire racks, etc., as well as adding interior decorations. When modifying a car, pay attention to the following points: Do not blindly pursue expensive parts: In fact, parts should be selected based on the actual condition of the vehicle. Do not blindly pursue excessive audio functions: Some believe that additional car audio features, such as wireless remote controls or multi-disc changers, are better. However, the audio head unit is the core determinant of sound quality, while speakers, crossovers, amplifiers, and enclosures are crucial for good sound. Other auxiliary features offer little actual improvement in sound quality. Do not overemphasize soundproofing: Some demand extreme soundproofing, even to the point of not hearing the engine. However, if the driver cannot hear road or powertrain sounds, they lose critical feedback on road and vehicle conditions, compromising safety. Do not blindly pursue visual effects: Installing oversized exhaust pipes or spoilers for appearance may be meaningless for small-displacement vehicles. Some even remove bumpers and replace them with decorative components. In a collision, the lack of bumper protection can cause severe damage to both the car and passengers.

What Causes the Failure of Car Power Window Switches?

Car power window switch failure can be caused by aging and deformation of the glass sealing strip, dirt or foreign objects in the window lifting guide rail, motor malfunction, low battery power, or window regulator failure. Issues with the glass sealing strip: Aging, excessive dirt, or deformation of the glass sealing strip (including inner trim strips) can create resistance when raising or lowering the window. Generally, if the strip is aged or deformed, it is best to replace it with a new one, or simply clean it. Solution: Spray some dashboard wax or apply talcum powder (for lubrication) on the glass sealing strip, which usually yields good results. Dirty window lifting guide rail: If the window lifting guide rail is too dirty, it can also cause lubrication issues. Solution: Clean the window lifting guide rail and apply lubricating grease to eliminate the problem. Low battery power may also lead to difficulty or failure in window operation. When raising or lowering the window with the engine off, the power is drawn from the battery. If the battery is low on charge, window operation may become difficult. Window regulator failure: Window regulator malfunction, improper glass sealing strip, including guide rail failure, cable failure, or slider failure, etc. Solution: The only remedy is to replace the window regulator.

Can car wash shops inflate tires?

Generally, most car shops can provide inflation services, but it's better to go to a professional tire shop for inflation as the air pressure will be more accurate. Many car wash shops have inaccurate pressure gauges. Below is some information about car tire pressure: Introduction: Tire pressure, strictly speaking, refers to the air pressure inside the tire. High tire pressure: This reduces the contact area between the tire and the ground, leading to poorer tire grip, longer braking distances, and compromised driving safety. Low tire pressure: This causes excessive wear on certain parts of the tire, shortening its lifespan, and can easily lead to bending and breaking of the tire sidewall, resulting in a blowout accident.
