Here are the reasons and solutions for a car electric fan not working: 1. Water temperature not reaching the required level: Most car radiator fans operate based on electronic temperature control, so the fan will only start working normally when the internal water temperature reaches the specified level. If the temperature is too low, the radiator fan will not rotate. 2. Relay malfunction: If the water temperature meets the requirements but the car radiator fan still does not work, the issue might be with the fan's relay. A faulty relay can prevent the radiator fan from operating. The solution is to replace the damaged relay. 3. Thermostat switch problem: If the above two issues are not present, it's necessary to check the thermostat switch, as it can also affect the operation of the car radiator fan. The solution is to replace the faulty thermostat switch.

What Causes the Car Tire Pressure Warning?

The car tire pressure warning is triggered when the pressure in the four tires falls outside the normal range, usually due to slow leaks, punctures causing underinflation, or overinflation. Methods to reset the tire pressure warning include: 1. Visit a 4S shop and have technicians use professional diagnostic tools to reset it; 2. Press and hold the tire pressure monitoring button to reset. Tire pressure refers to the air pressure inside the tires, which is essentially the 'blood pressure' of a car. The level of tire pressure plays a crucial role in the vehicle's performance and power. Nowadays, many tires are filled with gases other than air, and these tires have stricter pressure requirements. For tires filled with air, pressure adjustments may be needed with seasonal changes, and tire pressure is closely linked to vehicle performance, such as comfort and load capacity, as well as affecting tire lifespan.

Why does a sedan's brakes make noise?

Car brakes making abnormal noises can be attributed to the following reasons: 1. The car is new or has just had new brake pads installed, which is a normal phenomenon. 2. Rust on brake discs or pads: After parking for a long time, especially in humid weather or after rain, some rust or dirt may appear on the brake discs or pads. In this case, you can apply butter or special lubricating oil at the connection between the brake pads and the brake calipers. 3. Excessive wear of brake discs and pads: Both brake discs and pads are high-wear items. Every time you brake, these two components rub against each other, leading to natural wear over time. When the wear becomes excessive, abnormal noises may occur, so regular inspection and replacement are necessary.

How soon can I reschedule after failing Subject 2?

After failing Subject 2, you must wait at least 10 days before rescheduling. Below are the specific details regarding Subject 2 rescheduling: 1. According to Article 44 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," each subject can be taken once, with one retake allowed if failed. If you do not take the retake or fail it again, the current examination ends. Applicants must reschedule the exam, but Subject 2 and Subject 3 exams must be scheduled at least 10 days later. If you fail the Subject 3 safety and civilized driving knowledge test, the previously passed road driving skills test scores remain valid. 2. Within the validity period of the driving study certificate, the number of rescheduling attempts for Subject 2 and Subject 3 road driving skills tests must not exceed five. If you fail the fifth rescheduled exam, all previously passed subjects will be invalidated.

How to Remove Dirt from White Car Paint?

White car paint dirt removal methods are introduced as follows: 1. Asphalt: If a large amount of asphalt is adhered to the car body, it can be cleaned with a tar remover. Remember to wear gloves when using the tar remover. 2. Bird droppings and other impurities: For vehicles frequently parked under trees, they are bound to be attacked by bird droppings or tree sap and other impurities. If the stains on the car body are substances like bird droppings, they can be soaked with car shampoo or glass cleaner, and after softening, they can be easily removed. 3. Iron powder: If the stains on the car body are dense iron powder, the above cleaners cannot remove them. Only by using special clay bars or stain removal cloths, and slowly grinding them after washing the car body, can they be removed. (Excessive use of clay bars/cloths may cause the paint surface to lose luster and become dull, so after use, it is advisable to apply a layer of wax to the car body.)

How to Determine if the Drive Shaft Bearing is Faulty?

Here are the methods to determine if the drive shaft is damaged: 1. Damage, wear, deformation, or loss of dynamic balance in the drive shaft can cause abnormal noises and vibrations while driving. 2. During driving, noises may occur when starting or accelerating sharply, accompanied by a feeling of loose components. Below is an analysis of the causes of drive shaft failure: 1. Loose connections (or connecting bolts) at the flange joints of the drive shaft. 2. Loose fixing bolts of the intermediate support bracket of the drive shaft, resulting in excessive clearance between the intermediate support and the intermediate drive shaft journal. 3. Disintegration of the intermediate support bearing of the drive shaft, damage to the bearing raceway, poor bearing lubrication, or excessive wear leading to looseness. 4. Misalignment of the intermediate support bracket installation position, improper adjustment of bearing preload, damage to the rubber spacer ring, or incorrect tightening torque of the intermediate support bracket fixing bolts (either too tight or too loose) causing bracket misalignment, leading to abnormal noises.

How to Use the Foot Brake in an Automatic Transmission Car

Here are the steps to use the foot brake in an automatic transmission car: 1. After the vehicle comes to a complete stop, shift the transmission to the Neutral (N) position. 2. Press down the parking foot brake (this will engage the parking brake) and turn off the engine. 3. After pressing the automatic transmission foot brake, shift the transmission from the N position to the Park (P) position. The method to activate the automatic transmission foot brake is as follows: 1. When starting, first press the brake pedal with your right foot, shift the transmission to the N position, and start the engine. 2. After the engine starts, press the parking foot brake again with your left foot. This will release the parking brake, and the parking foot brake will return to its original position under spring force. 3. Shift the transmission from the N position to the Drive (D) position and slowly release the brake. The vehicle can now move forward.
