Reasons why the car air conditioner blows hot air: 1. The air conditioner is not set to cooling mode; 2. The air conditioner is in external circulation mode; 3. The car air conditioning system lacks refrigerant (Freon); 4. The compressor is slipping or loose; 5. The car air filter is too dirty. Reasons why the car air conditioner does not blow air: 1. Blower motor failure: The car blower motor is a crucial component for air output. If the air conditioning compressor fails during use, the car air conditioner will definitely not blow air. 2. Clogged air filter: The air filter is a significant and common reason for the air conditioner not blowing air. During operation, the car air conditioner absorbs many impurities from the air. 3. Control system failure: Possible issues include the air vent, air conditioning computer, or control switch malfunction. Control system switches generally do not fail, so it is recommended that car owners visit a 4S shop for inspection, as this will simplify the troubleshooting process.

What items are required for a 20,000-kilometer car maintenance?

Generally, a 20,000-kilometer car maintenance is a major service, typically the third maintenance for a vehicle. Routine items include replacing the engine oil, oil filter, air filter, cabin air filter, spark plugs, etc. Relevant information about the oil filter is as follows: 1. Replacing the engine oil and oil filter is essential. Under the harsh conditions of high temperature and high pressure inside the engine, the shelf life of engine oil is significantly shortened, and its performance deteriorates substantially. Over time, it fails to protect the engine effectively. 2. The oil filter prevents impurities from mixing with the engine oil, which could cause oxidation and lead to the formation of sludge and clog the oil passages. Both the engine oil and the oil filter should be replaced simultaneously.

W: Winter/Snow mode, typically used in snowy or rainy weather for driving on slippery or snowy surfaces. 3. E: Economy mode, as the name suggests, selecting this gear can save fuel. 4.

What does it mean when the Audi A3 displays a safety system malfunction?

The instrument panel indicates an electronic system malfunction in the vehicle, which is caused by insufficient battery power leading to momentary voltage deficiency during startup. Additionally, considering that the actual battery voltage does not drop below 12.2V when the ignition is turned to position 15#, the battery warning light remains off when stationary. However, after startup, the vehicle's electrical system voltage normalizes due to the alternator's operation. Resetting the electronic system: Turn the ignition key on, then press and hold the foot brake. Next, push down the electronic parking brake for 5 seconds, followed by pulling it up for another 5 seconds. This procedure initializes and resets the electronic parking brake. Function of the parking brake: The parking brake serves to stabilize the vehicle after it has come to a complete stop, preventing accidents caused by rolling on inclined surfaces.
