It is caused by the continuous closure of the wiper relay. This relay is located inside the wiper combination switch and requires replacement of the combination switch. Here is some relevant information about wipers: Function of wipers: Wipers, also known as windshield wipers or water wipers, are devices used to remove raindrops and dust attached to the vehicle's windshield, thereby improving the driver's visibility and enhancing driving safety. Due to legal requirements, almost all cars worldwide are equipped with wipers. Working principle of wipers: They use a DC permanent magnet motor. The wiper motor installed on the front windshield is generally integrated with the worm gear mechanical part. The function of the worm gear mechanism is to reduce speed and increase torque. Its output shaft drives a four-bar linkage mechanism, which converts continuous rotational motion into left-right oscillating motion.

What are the reasons for the overflow of the expansion tank?

The reasons for the overflow of the expansion tank: 1. When the engine temperature is too high, the coolant will boil and overflow from the expansion tank cap due to excessive pressure. The cause of the high engine temperature should be identified and addressed; 2. The water temperature is too high. During driving, cooling relies on natural wind and the fan. After stopping and turning off the engine, the fan stops working; 3. Blockages in the radiator or hoses, or leaks in the radiator cap or the cap connecting to the engine. The car radiator, also known as the heat exchanger, is a key component in the car's cooling system, functioning to dissipate heat. The radiator is usually located behind the air conditioning condenser. Opening the engine compartment only reveals the upper cover of the radiator. To see the radiator's position, the front bumper cover needs to be removed.
