There are several reasons why the fan does not rotate when the air conditioner is turned on in an old Polo, including poor motor lubrication, reduced starting capacitor capacity, and prolonged motor usage. Below are the detailed explanations: 1. Poor motor lubrication: The fan does not rotate because the motor lacks sufficient lubrication, preventing it from driving the fan blades after installation. 2. Reduced starting capacitor capacity: The capacitor capacity decreases, leading to a reduction in the motor's starting torque, making it unable to drive the load. 3. Prolonged motor usage: After prolonged use of the fan, the motor wears out. When the motor's shaft sleeve wears, it is prone to burning out. Extended use of the motor also increases its internal resistance, reducing its load-bearing capacity and preventing it from driving the fan blades.

Where is the OBD port on the Touran?

Location of the Volkswagen Touran OBD interface: It is located behind the plastic cover under the steering wheel. First, open the driver's glove box, then remove the glove box, and you will see the OBD interface on the right side behind the glove box. Here is some related information about OBD: 1. OBD is the abbreviation for On-Board-Diagnostic, which translates to "On-Board Diagnostics" in Chinese. This system continuously monitors the engine's operating conditions and the working status of the exhaust after-treatment system. If it detects any situation that may cause excessive emissions, it will immediately issue a warning. 2. When a fault occurs in the system, the Malfunction Indicator Lamp (MIL) or Check-Engine warning light will illuminate. At the same time, the OBD system will store the fault information in the memory. The relevant information can be read in the form of fault codes through standard diagnostic tools and interfaces. Based on the fault codes, maintenance personnel can quickly and accurately determine the nature and location of the fault.

Where is the ESP switch of Audi A6L?

The ESP switch of the Audi A6L is located below the air conditioning screen on the center console. The ESP can be temporarily turned off under the following circumstances: 1. When the vehicle is stuck in mud. The ESP system reduces engine torque, which can exacerbate wheel slippage. 2. During extreme driving. Actions such as drifting around corners or performing a launch start require a certain degree of slippage, making it necessary to turn off the ESP. 3. On roads with deep snow. On slippery snow-covered roads, the tires already have insufficient grip. If the ESP continues to intervene, it will only cause the wheels to sink deeper. However, when the snow is just beginning to melt, remember not to turn off the ESP, as this could lead to even more severe slippage. 4. When snow chains are installed on the tires. Changes in the tire's outer diameter may cause the sensors to mistakenly interpret this as a tire malfunction, leading the ESP to continuously issue warnings, which can affect driving.
