Where is the car fuse located?

The car generally has two fuses. One is located inside the engine compartment and is responsible for the normal operation of the vehicle's external electrical components, such as headlights, horn, engine control unit (ECU), air conditioning compressor, windshield washer motor, and other circuits for safety protection. The other is located on the left side of the steering wheel or inside the glove box, responsible for the normal operation of the vehicle's internal electrical components, such as power windows, cigarette lighter, power seats, and airbags. The fuse, also known as a circuit breaker, primarily functions to blow and cut off the circuit when the current is abnormal or exceeds twice its rated current, thereby protecting the circuit. Fuses have two important parameters: one is the rated current, and the other is the rated voltage. When replacing a fuse, it is essential to select the corresponding specifications based on the fuse's current and voltage ratings.

Is it necessary to apply film on the front windshield of a sedan?

Applying film on the front windshield of a sedan is generally unnecessary unless the windshield has sustained certain damages or cracks, in which case applying film may indeed be necessary. If the windshield cracks, the car window film can act as an adhesive, holding the shattered glass together and reducing the severity of injuries to the driver. However, under normal circumstances, a windshield would not be driven with existing damages. Potential drawbacks of applying film include: it may obstruct the driver's vision, cause reflections on the car body that affect the visibility of vehicles behind, and increase the likelihood of rear-end collisions. If a metallic film is applied, it may also interfere with ETC and GPS signals and cause issues like high reflectivity.

How to Solve Loud Car Engine Noise?

Solutions for loud car engine noise: 1. Poor fuel quality causing loud engine noise: When low-quality fuel is used, the combustion inside the engine deteriorates, leading to strong vibrations and noise during operation. The solution is to promptly switch to high-quality fuel. 2. Loose plastic parts in the engine compartment causing noise: If inspection confirms that the noise is coming from plastic components, tightening them can resolve the issue. 3. Loose engine mounts causing loud engine noise: Engines are typically supported and fixed by engine mounts, which can age and loosen over time, leading to noise during operation. Inspecting and tightening the engine's mounting components can alleviate the noise. 4. Loud engine noise during cold starts: When a vehicle has been parked for an extended period, all the lubricating oil flows back to the oil pan, preventing the engine from receiving adequate lubrication. This is a normal phenomenon.

Does the ETC device require wiring?

There are two power supply methods for ETC devices. One is the solar-powered ETC electronic tag, which can automatically charge without wiring. The other is the ETC electronic tag that requires additional power supply (such as cigarette lighter power supply or battery power supply). The cigarette lighter power supply requires wiring, while the battery power supply does not require wiring. The battery has a validity period of 3 years, and a new battery can be replaced after 3 years. The wiring method for cigarette lighter power supply: 1. Take out the ETC device and stick it to the upper middle part of the front windshield with 3M adhesive; 2. Reserve 5 to 10 cm of the ETC device's power supply connection cable, and insert the cable into the gap of the top trim panel; 3. At the turning point, a plastic pry bar can be used to insert the connection cable, extending along the sealing strip all the way to the passenger foot space; 4. Lift the passenger foot mat and hide the connection cable under the mat; 5. Plug the connection cable into the cigarette lighter to obtain power, and the ETC installation is completed.

What measures should be taken in case of brake failure?

After the brake system fails, you should downshift to use engine braking to slow down. If the speed still cannot be reduced, you can try to slow down by rubbing against the wall or railing on the side of the road. If this is necessary, ensure the safety of other pedestrians and vehicles. Do not use the handbrake in case of brake failure: If the brake system fails, do not use the handbrake, as this may directly cause the car to lose control. Composition of the brake system: The brake system is very important for a car. It mainly consists of a vacuum booster pump, master cylinder, wheel cylinder, brake pads, and brake discs.

What Are the Reasons for a Car Not Starting in Cold Weather?

The reasons for a car not starting in cold weather: 1. Insufficient battery power: In low temperatures, the car's power consumption increases, and the battery capacity decreases. You can go to a specialized shop to recharge the battery or replace it with a new one in time; 2. Restricted oil flow: In winter, the viscosity of the engine oil increases, making it difficult to flow, which increases the engine resistance and makes it hard to start the car. You can place the car in a warm environment, and after a while, it can start normally. A complete solution requires professional winter maintenance and changing to the appropriate engine oil; 3. Frozen exhaust pipe, carbon buildup in the electronic throttle: The condition of a frozen exhaust pipe mainly occurs when the car is used infrequently. The water vapor from engine combustion freezes on the exhaust pipe, and short-distance driving is not enough to melt this ice. After one night, more ice forms, and over time, it will affect the vehicle's starting and exhaust. The solution is to drive at high speed to use stronger exhaust force to promptly remove the accumulated water in the exhaust pipe.
