Car blower failure symptoms include: no air blowing out from the air conditioning vents, and the car owner should promptly replace the faulty blower. The blower is a crucial component in the air conditioning system, as it enables the air conditioning vents to blow air. For heating: When the warm air function is activated, high-temperature coolant from the engine flows through the heater core. At this time, the air blown by the blower also passes through the heater core, allowing warm air to be blown out from the vents. For cooling: When the AC button is pressed, the compressor clutch engages, causing the engine to drive the compressor. The compressor continuously compresses the refrigerant and delivers it to the evaporator, where the refrigerant expands and absorbs heat, cooling the evaporator.

What to Do When Taking the Driving Test (Subject 3) in the Rain?

When taking the Subject 3 driving test in the rain, you should pay attention to the following: 1. Adjust your mindset and prepare for the worst-case scenario before the test to avoid excessive nervousness; 2. Roads become slippery on rainy days, so be prepared to slow down in advance when stopping at traffic lights or pulling over; 3. Drive slowly in the rain, especially when turning or making U-turns; 4. Maintain a safe distance from other vehicles, as slippery roads increase braking distance. Subject 3 covers safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling procedures.

How to Determine the Position of the Wheels?

The methods to determine the position of the wheels are: 1. Observe the nodes on both sides of the wiper to judge; 2. Use the side mirrors to observe the door handles on both sides, where the door handles coincide with the solid lines on the ground; 3. Determine the position through the center of the windshield. The methods to judge the distance to the vehicle ahead are: 1. When the upper edge of the front vehicle's bumper is visible from the lower edge of the windshield, the distance to the front vehicle is about one meter, requiring control of the distance; 2. When the lower edge of the front vehicle's bumper is visible from the lower edge of the windshield, the distance is about two meters; 3. When the rear tire's lower edge of the front vehicle is visible from the lower edge of the windshield, the distance is about three meters.

Will points be deducted for parallel parking exceeding 30 centimeters?

After completing parallel parking, if the distance exceeds 30 centimeters, 10 points will be deducted. Other point-deduction scenarios for parallel parking include: stopping midway results in a 100-point deduction; tires touching or crossing the lane boundary lines during movement deducts 10 points; the vehicle body extending beyond the lines after parking deducts 100 points. Although the rules state that stalling the engine due to improper operation deducts 10 points once, stalling during parallel parking is equivalent to stopping midway, which directly deducts 100 points. Precautions for the Subject 2 driving test: Fasten the seatbelt: Buckle up immediately after getting in the car. Ensure the seatbelt is not fastened incorrectly or to the co-driver's side, as the system will directly deem the test failed. Do not unfasten the seatbelt during the entire test. Vehicle preparation procedure: After entering the vehicle, adjust the seat and mirrors, fasten the seatbelt, turn on the left turn signal, shift to first gear, and release the handbrake. These six steps are essential—ensure all preparations are complete before starting. No stopping during the test: There is no time limit for reversing into the parking space, but it is crucial not to stop during the process. If the wheels remain stationary for 3 seconds, the system will judge it as stopping midway, so controlling the speed is vital. Hill start time limit is 30 seconds: The hill start must be completed within 30 seconds, with the system providing a voice reminder every 10 seconds. Exceeding 30 seconds results in immediate failure.

How to Determine if a Car's Air Conditioning is Low on Refrigerant?

Methods to determine if a car's air conditioning is low on refrigerant: 1. During normal continuous operation of the air conditioning, if there are continuous bubbles in the sight glass, it indicates a lack of refrigerant; 2. Open the car hood and check for oil stains at the air conditioning system joints—if present, it indicates a lack of refrigerant; 3. During normal continuous operation of the air conditioning, if there are no bubbles in the sight glass, but brief bubbles appear when the air conditioning stops, it indicates the refrigerant level is normal. The process of refilling air conditioning refrigerant is: 1. Evacuate the system, close the manual valves on the pressure gauge and the high and low pressure manual valves; 2. Connect one end of the hose to the injection valve fitting of the refrigerant can; 3. Open the refrigerant can, loosen the nut on the pressure gauge hose to allow some gas to escape, then close it; 4. Open the high-pressure side manual valve and invert the can; 5. Inject the specified amount of liquid refrigerant, then close the refrigerant injection valve and the high-pressure manual valve.
