What is the reason for uneven cooling in the Nissan Sylphy's air conditioning system?

Nissan Sylphy car air conditioning system experiencing uneven cooling (one side cold while the other not) generally has the following causes: Air vent issues: Damage to one of the air vent servo motors, resulting in one side of the air conditioning not cooling; check the direction of the left and right air vents, observe the servo motor controlling the airflow direction on the right side, and see if the motor rotates accordingly. Air valve plate issues: Inspect whether the air door has malfunctioned. If the air valve plate is stuck, it will hinder the rotation of the valve plate, directly affecting the airflow output. Air duct blockage: Blockage in one side of the air duct, causing uneven cooling in the air conditioning system. Dual-zone control function activated: If it is an automatic air conditioning system, the dual-zone control function might be activated; simply deactivate the dual-zone air conditioning function.

What Are the Causes of Low Car Idle Speed?

The causes of low car idle speed are: 1. Fuel accumulation or carbon buildup in the throttle body; 2. Dirty intake manifold; 3. Weak spark due to faulty spark plugs; 4. Malfunctioning idle control valve; 5. Poor atomization or clogging of the fuel injector; 6. Changes in oil viscosity. The solutions for low car idle speed are: 1. Check the throttle body for fuel accumulation or carbon buildup; 2. Clean the intake manifold; 3. Inspect the condition of the spark plugs; 4. Check if the idle control valve is malfunctioning; 5. Examine the fuel injector for issues; 6. Replace the engine oil promptly. The causes of high car idle speed are: 1. Idle switch not closing; 2. Faulty idle control valve; 3. Air leak in the intake pipe; 4. Incorrect valve timing; 5. Fuel injector dripping or clogging; 6. Blocked exhaust system; 7. EGR valve opening during idle conditions.

Is It Normal for Water to Drain from a Car's Exhaust Pipe?

It is normal for water to drain from a car's exhaust pipe, indicating that the engine is operating properly, with complete combustion and effective atomization. The exhaust pipe consists of a front exhaust pipe and a rear exhaust pipe, and its functions include: 1. Vibration and noise reduction; 2. Facilitating installation; 3. Extending the lifespan of the exhaust muffler system. The maintenance methods for the exhaust pipe are: 1. Waterproofing: When driving in the rain or going for a car wash, be careful to prevent water from entering the muffler, which can cause rust and affect the exhaust pipe's performance; 2. Rust prevention: Remove the muffler, block the drainage hole, add rust-proof oil, and ensure it spreads evenly inside the cylinder before reinstalling the muffler; 3. Cleaning: The exhaust pipe is often exposed to the outside, similar to the interior of the car, and accumulated dirt can hinder its normal function, so regular cleaning is essential.

What are the reasons why a dash cam cannot start?

The reasons why a dash cam cannot start may include a depleted or damaged battery, or a faulty power supply circuit. If the dash cam can power on using an external power source, such as through the cigarette lighter socket or a mobile phone charger connected to mains power, then it can be confirmed that the built-in battery of the dash cam is damaged or the voltage is too low, causing the failure to start. The solution is to power the dash cam using an external power source or replace the built-in battery. If there is a broken circuit in the power supply circuit on the dash cam's motherboard, it can prevent normal power supply. Since dash cams usually operate in high-temperature environments, it is necessary to consider whether components on the circuit board have become loose due to soldering issues. The solution is to first remove the SD card or TF card and press the power button to check if the device can start. If it still does not start, check the side of the device for a "RESET" hole and gently press it with a soft object, then press the power button again to see if it starts. If the dash cam starts normally, it indicates an issue with the card. In this case, format the card.
