What Causes Wind Noise from Car Windows Without Actual Air Leakage?

Wind noise from car windows without actual air leakage can be attributed to the following reasons: Loose Door Seals: It is highly likely that the wind noise is caused by loose door seals. For this issue, it is recommended to thoroughly inspect the sealing performance of the door rubber seals to check for any deformation or improper installation that might compromise the seal. Such issues can be addressed with free repairs during the vehicle's warranty period. Therefore, it is advisable to promptly visit a 4S dealership for further on-site inspection and diagnosis by a technician. Solution: Lower the window glass and press down on the upper right corner of the seal near the door frame. A small hole will appear, and this is where the wind enters, causing the wind noise. Roll 3M double-sided tape into small xylitol-sized pieces and gradually fill the hole until it is completely packed. This should resolve the issue.

What is the reason for not hearing the fuel pump sound when turning the key?

The reasons for not hearing the fuel pump sound when turning the key are as follows: Fuel pump damage: The fuel pump is damaged. The fuel pump does not start, and no oil pressure is established. During secondary ignition, the crankshaft sensor forcibly starts the pump. The function of the fuel pump is to draw gasoline from the fuel tank and press it through the pipeline and fuel filter to the float chamber of the carburetor. Insufficient fuel: First, check whether the fuel level is sufficient and see if the fuel pump can draw fuel. If the fuel level is sufficient, check the fuel pump fuse. If the fuse is not broken, it is recommended to go to a 4S service station to check the fuel line, not the clogged fuel filter.

What is the problem when the rear car cannot stop?

The reason why the rear car cannot stop may be due to a lack of necessary maintenance of the braking system, or mechanical failure caused by improper operation. Brief introduction to the causes of brake failure: There are many reasons for brake failure. First, it could be due to a lack of necessary maintenance of the braking system, such as excessive impurities in the brake master cylinder, poor sealing, failure of the vacuum booster, dirty brake fluid or the formation of vapor locks when different types of brake fluid are mixed and heated, leakage in the brake master cylinder or wheel cylinders, or air leaks in the air reservoir or pipeline connections. Second, improper operation may lead to mechanical failure, such as prolonged downhill driving causing the brake pads to overheat, carbonization of the brake drums, and complete loss of braking function. Third, severe overloading increases the vehicle's inertia due to gravitational acceleration, directly resulting in brake failure. How to handle brake failure while driving: Control the direction according to the road conditions and speed, disengage the high gear, and quickly rev the engine once to shift from high gear to low gear. This will create significant engine braking resistance, rapidly reducing the vehicle's speed. Additionally, while shifting to low gear, use the handbrake in combination, but be careful not to pull it too tightly or too slowly. Pulling it too tightly may cause the brake disc to "lock up," potentially damaging the transmission components and losing braking ability. Pulling it too slowly may cause excessive wear and overheating of the brake disc, rendering it ineffective. Use the vehicle's rigid parts, such as the bumper or body, to rub or collide with natural obstacles on the roadside (rocks, large trees, or slopes) to force a stop and minimize accident losses.

What are the reasons for a heavy steering wheel in the Teana?

The reasons for a heavy steering wheel in the Teana are as follows: Power steering pump failure: When the pump pressure of the power steering pump fails to meet the standard value, the steering wheel will feel heavy during use. It is necessary to inspect the flow control valve. If there is leakage in the flow control valve or safety valve during driving, it can be repaired by grinding. Then, check whether the spring of the safety valve has failed. Steering gear failure: When the hydraulic pressure of the steering gear is low, the steering will feel heavy. If the steering wheel becomes heavy due to the hydraulic pressure of the steering gear, it is necessary to seek professional repair from a specialized manufacturer. It is not recommended for the car owner to handle it themselves. Lack of oil or air in the power steering system: When there is air in the car's steering system, not only will the steering feel heavy, but there will also be noise during steering. This needs to be addressed promptly to avoid greater losses. Clogged return oil filter in the oil reservoir: If the return oil filter in the oil reservoir is not maintained or replaced for a long time, it can easily become clogged, leading to poor circulation of the power steering oil and a heavy steering wheel.

What Are the Procedures for Professional Car Washing?

Professional car washing consists of four procedures. Vacuuming and tidying up interior items: The first step of cleaning should be to remove dust from the interior of the car, sweep away large debris, and then use a vacuum cleaner to suck up dust from the carpets and gaps between seats. Cleaning the control compartment: The dashboard and steering wheel are mostly made of plastic and leather, which easily attract dust but are also relatively easy to clean. It is important to note that since the dashboard is exposed to sunlight for long periods, it is prone to aging and becoming brittle. Therefore, it is best to choose a high-quality dashboard wax to spray, then wipe it clean with a dry cloth to properly protect the dashboard. Cleaning the air conditioning ducts: Remove the air conditioning vents, insert the thin tube of the air conditioning cleaner into the ducts, and spray an appropriate amount of cleaner. Then close the vents, turn on the air conditioning's internal circulation, start the engine, and let it idle for about 10 minutes. Also, clean the air conditioning filter. Cleaning the seats: When cleaning seats made of velvet or other fabric materials, spray high-efficiency foam cleaner onto the stains, let it sit for a while, and after the foam is completely absorbed, wipe carefully with a clean dry towel repeatedly until the stains are removed.

What Are the Reasons for a Car Being Locked and Unable to Start?

The reasons for a car being locked and unable to start are as follows: Steering Wheel Lock: It is common for car owners to report that their car won't start, and the key won't turn. In such cases, it is necessary to check whether the steering wheel was straightened when parking. If the steering wheel is at a slightly larger angle (e.g., more than 30 degrees), the steering wheel will automatically lock as an anti-theft measure. At this point, the key may not turn, and the car won't start. The solution is simple: just turn the steering wheel forcefully while turning the key to unlock the steering wheel. Not in P Gear: If the car can be started in D gear or R gear, the sudden movement of the vehicle during ignition poses a significant safety hazard. Therefore, for automatic transmission vehicles (AT, CVT, AMT), manufacturers preset this mode and repeatedly emphasize in the manual: ensure the gear is in P position when starting. However, modern cars will remind the driver through the central dashboard if the gear is not in P when parking, sometimes accompanied by a beep, so the likelihood of this happening is very low. It usually occurs when the driver hastily turns off the engine in D gear and leaves the car, only to overlook this issue when getting back in.
