At what temperature does the Audi A6 electric fan start working?

What are the reasons why the Haval H2 does not blow cold air when the AC is turned on?

Haval H2 does not blow cold air when the AC is turned on for the following reasons: 1. Lack of refrigerant: Even if the air conditioning system is tightly sealed, refrigerant loss can occur, especially if there are minor leaks in the air conditioning pipes or condenser, leading to a lack of cooling. 2. Dirty condenser: The main purpose of cleaning the radiator and condenser is to dissipate heat. If debris is clogging the condenser, it can cause the engine temperature to rise too high or the air conditioning to not cool properly. 3. Damaged air conditioning compressor or expansion valve: Malfunctions in the expansion valve or throttle valve directly result in the air conditioning not cooling, requiring professional repair at a service center. 4. Aged or loose belt: If the air conditioning belt slips during use, it can lead to belt breakage, belt noise, loss of power assistance, or the air conditioning not cooling properly.

Automatic Transmission Subject 2 Deduction Items Details?

C2 test items include reverse parking, in addition, there are parallel parking, right-angle turns, and curve driving (commonly known as S-curve). Subject 2 has a full score of 100 points, with evaluation criteria set for failure, deduction of 20 points, deduction of 10 points, and deduction of 5 points. A total test score of 80 points or above is considered a pass. For Subject 2, there is one initial test attempt. If the test is failed, one retake is allowed. If the retake is not attended or is still failed, the current test session is terminated, and the applicant must reschedule the test after ten days. Within the validity period of the driving skill test permit, the number of scheduled attempts for Subject 2 and Subject 3 road driving skill tests must not exceed five. If the fifth scheduled test is still failed, the results of other subjects that have been passed will be invalidated.

Will the Car Depreciate After Transmission Repair?

Transmission repair can lead to car depreciation, with specific circumstances as follows: 1. Introduction: The transmission is a core component of a car, and replacing the transmission in a new car will depreciate its value. 2. Maintenance Method: When shifting gears in a manual transmission, always ensure the clutch is fully depressed to completely cut off power, preventing gear impact and grinding during shifting, thereby reducing gear damage. 3. Temperature Maintenance: During car operation, pay attention to the transmission's temperature and any abnormal noises. If the casing temperature exceeds 70-80 degrees, it indicates some components inside the transmission are malfunctioning. Immediately stop the car for inspection and resolve the issue promptly. Car owners unfamiliar with transmissions can visit nearby repair shops for professional maintenance. 4. Precautions: Regularly check for looseness in fasteners and control mechanisms, and tighten or repair them as needed. 5. Gear Shifting Note: When shifting gears, ensure the gear lever is fully engaged to allow complete tooth length meshing, preventing the gear teeth from wearing into a conical shape, which could cause automatic gear disengagement.

Is It Harmful to Drive 5 Kilometers with the Handbrake On?

Driving 5 kilometers with the handbrake on is generally not a major issue, but prolonged driving in this condition can easily cause damage to the car's wheel hubs. Here is a detailed introduction about car handbrakes and wheel hubs: 1. Handbrake: The parking brake, commonly referred to as the handbrake, functions to provide resistance when parking, preventing the car from rolling. The parking brake, also known as the handbrake or the parking gear in automatic transmissions, locks the drive shaft or rear wheels. 2. Wheel Hub: The wheel hub (Car-Rim) is the central part of the wheel where the axle is installed, also known as the "rim" or "steel rim." Wheel hubs are prone to accumulating dirt, and if not cleaned for a long time, they may corrode or deform, posing safety hazards.

What Causes a Car Not to Start in the Rain?

There may be water leakage causing a short circuit in the ignition coil—simply drying it off should resolve the issue. In low temperatures, the battery's electrolyte viscosity increases, reducing its permeability and increasing resistance, which lowers the output power. This makes it difficult for the starter to crank the engine to the minimum starting speed, affecting engine ignition. Additionally, low battery voltage results in weak spark plug sparks, and the increased resistance between electrodes due to higher mixture density makes it harder to ignite the fuel-air mixture. Below are some precautions for car battery usage: 1. Always turn off lights: For example, forgetting to turn off headlights during the day, especially for beginners who may leave car lights on after playing with the vehicle, can drain the battery over time. Similarly, listening to music or using the air conditioning without the engine running can also deplete the battery. 2. Pay attention to maintenance: To prevent battery drainage, proper maintenance is essential. Avoid frequent engine starts—cars have their limits, and repeated starting can cause wear. If the car doesn't start on the first attempt, wait a moment before trying again. Continuous starting puts significant stress on the car, increases discharge, and gradually shortens the battery's lifespan.

What Causes No Response When Turning the Key and No Dashboard Lights?

No response when turning the key and no dashboard lights may indicate an issue with the car battery. Additionally, it's necessary to check if the starter fuse is blown. Below are solutions for dashboard lights not turning on: 1. Press the horn: Try pressing the horn to assess the battery's charge based on the horn's loudness. If the horn doesn't sound or is very weak, it indicates a depleted battery. Alternatively, try turning the key and listening carefully; if there's no sound at all, it likely means the battery is dead. 2. Low-voltage circuit fault: Common low-voltage circuit faults include insufficient battery charge, poor or tangled wiring connections, poor battery grounding, damaged distributor or Hall sensor, faulty ignition switch or poor wiring connections, and damaged transistor ignition control unit or poor wiring connections. Most low-voltage circuit faults are diagnosed using an ammeter or voltmeter to check each wire and eliminate the fault point. 3. High-voltage circuit fault: Common high-voltage circuit faults include detached or leaking high-voltage wires, cracked or punctured distributor cap, burnt or punctured distributor rotor, spark plug electrode gaps too large or too small, excessive spark plug carbon buildup, damaged spark plug insulators, and damaged ignition coil or detached wiring. Most high-voltage circuit faults are diagnosed using the high-voltage spark test method: detach the central high-voltage wire or a cylinder's high-voltage wire from the distributor, place the wire end 3-6mm away from the cylinder body, and start the engine to test for sparks. If there's a strong spark, the ignition system is functioning normally.
