There are several reasons why the Passat's vents may not be blowing air: Clogged air filter: Usually, after cleaning or replacing the filter, the air flow from the vents will return to normal. During inspection, you can remove the filter to see if the air volume increases. If it does, the filter is clogged; if there's no change, it's another issue. Damaged blower motor: If the blower motor is damaged, it will result in insufficient or no air being drawn in, preventing the air from being blown out through the vents. You can make a preliminary assessment by setting the fan speed and air volume to the maximum and listening to the sound of the blower motor. If it doesn't turn or the speed is low, there is a malfunction, and the owner should take the car to a 4S shop or repair shop for servicing.

Where is the windshield wiper?

The windshield wiper is located on the right side of the steering wheel. Pushing it upwards once activates intermittent wiping, and the speed increases the further you push it up. Pulling it all the way down stops the wiper. Below is an introduction to car windshield wipers: 1. Structure of the wiper: The wiper assembly includes components such as a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly. When the driver presses the wiper switch, the motor starts, and its rotational speed is increased in torque through a worm gear mechanism to drive the swing arm. The swing arm then drives the four-bar linkage, which in turn causes the shaft mounted on the front bulkhead to swing left and right. Finally, the shaft drives the wiper blade to sweep across the windshield. 2. Features of the wiper: It is heat-resistant, cold-resistant, acid and alkali-resistant, corrosion-resistant, fits the windshield well, reduces motor load with low noise, has strong water-repellent properties, and is soft enough not to scratch the windshield.

What to Do When You Run Out of Gas Midway?

Methods to handle running out of gas midway: 1. Borrow fuel from another car: Prepare a fuel can and a rubber tube, insert the tube into the fuel tank, lower the outlet end of the tube, and the fuel will flow out automatically; 2. Call a tow truck: Tow the car to a gas station, or consider using a friend's car to tow it, but be cautious with soft towing (using a rope to pull); 3. Call for fuel delivery service: Some 4S shops and road assistance companies offer fuel delivery services. When the fuel indicator light on the car dashboard lights up, it means the fuel is about to run out. Generally, the car can still travel about 50 kilometers after the light comes on before the fuel is completely exhausted. The fuel indicator light is controlled by a float sensor in the fuel tank. The sensor monitors the fuel level and sends this signal to the ECU, which then analyzes it comprehensively and displays the result on the dashboard.
