The window switch has malfunctioned due to poor contact, causing the windows to frequently fail to operate. More reasons for the power window malfunction in the Besturn B70 are as follows: Wiring issues: The window wiring has malfunctioned, such as a short circuit or open circuit, leading to frequent window operation failures. Window regulator malfunction: The window regulator has malfunctioned, causing the windows to frequently fail to operate. The specific issue can only be determined after inspection. Relevant details about the Besturn B70 are as follows: Dimensions: The all-new 2021 Besturn B70 has a body length of 4810mm, width of 1840mm, height of 1455mm, and a wheelbase of 2800mm. Exterior: The main highlight of the side profile is its fastback design. Additionally, a continuous door frame trim line enhances the side details. It is positioned as a mid-size sedan with ample space. Tires: The photographed Besturn B70 is equipped with 19-inch multi-spoke alloy wheels, which give the car a robust stance. It comes with Linglong tires, sized 225/45R19.

I once encountered a power window malfunction while driving my Bestune B70, which was quite a headache. That time, the passenger side window got stuck in the middle and wouldn't go down. After inspection, it was found that the gears of the window regulator motor were severely worn out, probably due to frequent use on dusty roads. There could be several major reasons for such issues: first, oxidation or dirt buildup on the internal contacts of the switch button leading to poor contact; second, rusting of the lifting mechanism components like the slide rails or cables causing them to jam; third, short circuits or blown fuses, especially in older cars with aging electrical systems. I've learned my lesson and now regularly clean the button area with a cleaner to prevent dust accumulation. I also make sure to close the windows during rain to avoid water damage to the components. If the window suddenly stops working, try gently tapping the door panel to see if it temporarily restores function. If not, it's best to visit a repair shop as soon as possible to avoid delaying the fix like I did.

Does a small cut on the side of the tire have any impact?

A small cut on the side of the tire does have an impact. The solutions for a small cut on the side of the tire are: 1. If the cut has damaged the internal cord fabric or is already broken, it is not recommended to repair it, and the tire needs to be replaced; 2. If the cut has not damaged the cord fabric, the tire can continue to be used, but it is necessary to regularly check whether the wound has expanded or if the cords have been damaged; 3. Regularly check the tire pressure and inflate the tires according to the front and rear tire pressures recommended by the car manufacturer and the tire manufacturer. The tire is one of the important components of a car, as it directly contacts the road surface and works together with the car suspension to cushion the impact during driving, ensuring good ride comfort and smooth driving, as well as good adhesion between the wheels and the road surface, improving the car's traction, braking, and passability, and bearing the weight of the car.

How to Determine if Car Tires Need Replacement

Below are methods to determine if tires need replacement: 1. Check tread wear depth. There are tread wear indicators (approximately 1.6mm high) in the tire grooves. When the tread wears down to the level of these indicators, the tire requires replacement. Under normal usage, tires typically last 50,000-80,000 km. Vehicles reaching this mileage should undergo thorough tire inspection. 2. Examine tread aging condition. Tire aging relates closely to service duration and operating environment. New tires generally last about 6 years, but harsh conditions or prolonged storage accelerate aging, manifested as extensive cracking on treads and sidewalls. Cracked tires require immediate replacement regardless of remaining lifespan, as they significantly increase blowout risks during high-speed driving. 3. Inspect sidewall damage or bulges. While sidewalls rarely sustain damage during normal driving, improper parking or obstacle clearance may cause sidewall scrapes. Damaged sidewalls cannot be repaired and necessitate replacement. Bulges indicate broken fabric plies or steel belts in sidewalls, posing imminent blowout risks that demand immediate tire replacement. 4. Consider replacement after multiple repairs. Vehicles operating in poor conditions frequently suffer punctures. A single tire shouldn't undergo excessive repairs - generally, more than three patches warrant replacement as multiple repairs substantially increase potential risks. 5. Address abnormal wear patterns. Prolonged vehicle use may cause alignment issues leading to uneven wear, cupping, scalloped wear, or out-of-round conditions. Besides degraded driving experience and increased noise, prolonged abnormal wear raises safety risks. Frugal owners may opt for tire rotation to balance wear, but severely worn tires (showing block or scalloped patterns) require prompt replacement.

What is the method to determine if the primer is exposed?

Determining if the primer is exposed involves: gently touching the scratch with your finger; if you can feel a noticeable unevenness, it indicates that the primer is exposed. The automotive primer is the first layer of paint applied directly to the surface-treated base component. It serves as the foundation of the entire coating system. The primer is designed to have excellent adhesion to the substrate and good compatibility with the intermediate or topcoat layers above. Additionally, it must possess strong anti-corrosion, anti-rust, oil resistance, chemical resistance, and water resistance properties. Solvent-based automotive primers primarily use nitrocellulose resin, epoxy resin, alkyd resin, amino resin, or phenolic resin as the base material. Pigments such as iron oxide red, titanium white, carbon black, and other fillers are used. The application methods include spraying and dipping.

What is the method to remove adhesive from car glass?

The methods to remove adhesive from car glass are: 1. Use a cotton swab to apply vinegar on the residual adhesive. After the vinegar and adhesive blend, wipe it off patiently with a cloth; 2. Apply essential balm on the adhesive and scrape it off with a knife; 3. Evenly apply alcohol on the residual adhesive. Once the adhesive is softened by the alcohol, wipe it clean; 4. Spray a specialized heat-insulating cleaner on the residual adhesive, which will melt in a short time, then wipe it clean with a cloth. The maintenance methods for car glass include: 1. Use specialized or suitable wiper blades and replace them in time; 2. Keep the glass surface clean; 3. Use car-specific glass cleaner.

What are the solutions for car engine knocking?

Solutions for car engine knocking include: 1. Reduce the ignition advance angle; 2. Use gasoline with the specified octane rating; 3. Clean the carbon deposits in the combustion chamber; 4. If knocking occurs while going uphill, shift to a lower gear promptly; 5. Do not shift into a forward gear too early when starting the car. Causes of car engine knocking include: 1. Carbon deposits in the combustion chamber; 2. Using gasoline with too low an octane rating; 3. Poor quality gasoline; 4. Incorrect ignition advance angle. Symptoms of car engine knocking include: 1. Knocking suddenly creates shock waves in the cylinder that impact in all directions, causing strong vibrations in the engine's pistons, cylinder walls, connecting rods, crankshaft, etc., and producing irregular metal knocking sounds; 2. Overheating of the cooling system; 3. Incomplete fuel combustion, resulting in black smoke in the exhaust.

What is the appropriate valve clearance for a car engine?

Car engine valve clearance is appropriate between 0.29mm and 0.35mm. Insufficient valve clearance can lead to a decrease in engine power and even cause valve burning. The functions of valves are: specifically responsible for inputting air into the engine and expelling exhaust gases after combustion. They are categorized by engine structure into: 1. Intake valve: draws air into the engine to mix with fuel for combustion; 2. Exhaust valve: expels burnt exhaust gases and dissipates heat. Symptoms of excessive engine valve clearance include: 1. Causing vehicle vibration and failure to start; 2. Reduced pressure in the cylinder, incomplete combustion, prone to carbon deposits; 3. Increased wear on pistons and cylinder liners.
