Based on the schematic diagram, the following factors can lead to the blower not working: damaged fuse related to the blower; malfunction of the blower itself; damaged blower speed control resistor; faulty air conditioning control module; wiring issues related to the blower. Below are the extended details: Troubleshooting process: After checking the fuse, air conditioning control module, and replacing the speed control resistor, the issue persists, suggesting a possible short circuit or open circuit. Using a multimeter, the continuity and resistance from pin 2 of the P20 connector on the air conditioning control module to pin 16 of the P29 connector on the blower were found to be normal. Further inspection revealed that the GY/WH wire from pin 3 of the P20 connector to pin 10 of the P29 connector on the blower was open. The fault was identified as a break in this wire. Upon inspection, the wire harness was found to be broken. After repair, the blower resumed normal operation. Reminder: This wire changes color after passing through a connector.

Where is the fuel pump fuse relay of Volkswagen Lavida located?

After opening the driver's door, there is a panel on the side of the dashboard. Unscrew the panel with a screwdriver, and the fuse box is inside; the relay is located in the relay box. Relay Overview: A relay is an automatic control device where the output undergoes a sudden change when the input (electrical, magnetic, acoustic, optical, or thermal) reaches a certain value. Automotive relays are the relays used in vehicles. Relay Characteristics: Automotive relays have high load-switching capacity, impact resistance, and vibration resistance. The power supply in vehicles is mostly 12V, and the coil voltage is mostly designed for 12V. In the engine compartment, the ambient temperature range requirement is -40°C to 125°C, while in other locations, it ranges from -40°C to 85°C.

What is the reason for the Nissan X-Trail battery failure not lighting up?

Nissan X-Trail battery failure not lighting up. It is due to low voltage in the battery. Introduction to Automotive Batteries: Automotive batteries are an essential part of a vehicle and can be divided into traditional lead-acid batteries and maintenance-free batteries. Structure of Automotive Batteries: Since the battery uses lead-calcium alloy for the grid frame, the amount of water decomposition during charging is minimal, and water evaporation is also low. Additionally, the sealed structure of the casing releases very little sulfuric acid gas. Therefore, compared to traditional batteries, it has advantages such as not requiring any liquid replenishment and having a long charge storage time.

Where is the Audi S4 rearview mirror heating switch located?

The switch is located on the driver's side door panel, resembling a comb-shaped button. The rearview mirror heating function automatically activates when the external temperature is below 20 degrees Celsius, effectively eliminating visibility issues caused by rainy or snowy weather, ensuring safe driving. The function of rearview mirror heating: The rearview mirror heating feature allows the car to remove rainwater or fog from the mirror surface during adverse weather conditions such as rain, snow, or fog, ensuring clear visibility. The principle of rearview mirror heating: It involves installing an electric heating element or film inside both rearview mirror lenses. Typically, there is a rearview mirror heating button on the car's central console. When activated, it quickly heats up, with temperatures generally ranging between 30 to 60 degrees Celsius.

Why does the Audi Q5L use a 7-speed wet dual-clutch transmission?

Audi Q5L uses a 7-speed wet dual-clutch transmission because: The working condition of the wet dual-clutch is better. Introduction to dry dual-clutch transmission: The clutch has poor thermal degradation, and the clutch is prone to overheating. If these changes cannot be well recognized by the computer, it will lead to a loss of electronic control accuracy. This can result in power interruption, shaking, or a sudden surge of power. Introduction to wet dual-clutch transmission: It is wet-type, immersed in oil, so the heat dissipation of the clutch is better, making the clutch wear and thermal degradation superior to that of the dry type. Moreover, the clutch temperature can be estimated through the oil temperature sensor, greatly improving control accuracy. Therefore, the problematic transmissions from Volkswagen are mostly the 7-speed dry dual-clutch type. Hence, the 6-speed dual-clutch transmission has better durability.

What Causes the Bumpy Noise in Baojun 510?

Baojun 510 bumpy noise causes: Suspension failure: Suspension failure can cause the car to have no damping or rebound when driving on bumpy roads, making it prone to noise when passing speed bumps or rough roads, accompanied by body shaking. Tire noise: Stones or other foreign objects stuck in the tire tread can also cause noise, often accompanied by rear body swaying. Brake failure: The bumpy noise may also be due to foreign objects between the brake pads and discs, or excessive wear of the brake pads, both of which can cause noise.

Can Skoda Octavia use 5w30?

Skoda Octavia can use 5w30. The recommended oil specification for Skoda Octavia is 5W-40, but it can also use 5W-30 oil. The viscosity of 5W-30 and 5W-40 oils is different, and you can choose the oil according to your specific situation. For new cars within two years, 5W-30 is recommended, while for cars older than two years, 5W-40 is recommended. In northern regions, 5W-40 is recommended. Oil Introduction: 5w represents resistance to low temperatures of -30 degrees Celsius (calculated as 5-35=-30. For example, 0w40 would be 0-35=-35 degrees Celsius). 40 represents high-temperature viscosity, which determines the strength of the oil film and the thickness of the lubricant. Oil Selection Method: According to China's climate conditions, all-season oil can be selected in most regions, suitable for both winter and summer. The universal oil grades for winter and summer are: 5W/20, 5W/30, 5W/40, 5W/50, etc. The smaller the number representing the winter part, and the larger the number representing the summer part, the higher the viscosity and the wider the applicable temperature range.
