The reasons for a burning smell from the car AC after starting the engine are: 1. The air intake of the AC is blocked, preventing the hot air inside from being blown out and causing the heat to accumulate, which burns the plastic components; 2. Aging wiring, where the circuit gets scorched by heat during electric heating, or plastic components shifting internally, leading to overheating. Maintenance methods for car AC: 1. Regularly check the refrigerant and compressor oil; 2. Clean the surface of the condenser; 3. Clean the surface of the evaporator. The functions of car AC are: 1. To adjust and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to an optimal state, providing a comfortable environment for passengers and reducing travel fatigue; 2. To create favorable working conditions for the driver, serving as a crucial ventilation device for ensuring safe driving.

Will a car take in water if it passes through a deep water section without stalling?

If a car passes through a deep water section without stalling, it indicates that no water has entered the vehicle. The engine is a fully sealed environment, and the only possible entry points for water are the air intake and exhaust ports. The exhaust port does not take in water during operation. Therefore, as long as the air intake is higher than the water level, no water will enter. If water enters the engine, the car will stall. If the car does not stall, it means no water has entered the vehicle. Precautions: When driving through water, it is essential to proceed slowly. If the water level rises above the exhaust pipe, maintaining a low gear and high RPM will prevent the vehicle from stalling. However, rushing through the water may cause water to enter the front exhaust ports, leading to stalling. Drive slowly in deep water. During heavy rain, turn on the front and rear fog lights because the dispersed light from the front fog lights is not dazzling and effectively alerts other vehicles to yield. Hazard lights should only be used in special situations because when they are on, the turn signals become ineffective. If you need to turn, following vehicles may not understand your intention in time, increasing the risk of an accident. On rainy days, the temperature outside is usually lower than inside the car, causing the windshield to fog up and obstruct the driver's view. In this case, turning on the air conditioner's cold air can help clear the fog.
