What Causes Car AC to Not Cool at High Speed but Cool at Low Speed?

Insufficient or low refrigerant in the car's air conditioning system is the primary reason for the AC not cooling at high speed but functioning at low speed. Below is a detailed explanation: 1. Insufficient Refrigerant: A lack or shortage of refrigerant in the car's AC system can lead to inadequate cooling. The most common cause of insufficient refrigerant is minor leaks in the system. If the refrigerant level is low, the amount sprayed into the evaporator from the expansion valve decreases, resulting in reduced heat absorption during evaporation. Consequently, the cooling capacity drops. If the refrigerant is insufficient, it should be replenished. However, when adding refrigerant, note that if filling from the low-pressure side, ensure the refrigerant bottle is not laid flat. If filling from the high-pressure side, do not start the engine. 2. Moisture in the AC Refrigeration System: The presence of moisture in the car's AC refrigeration system can cause insufficient cooling or complete failure. If moisture is the culprit, the desiccant or dryer in the car's AC should be replaced, followed by evacuating the system and refilling it with the appropriate amount of new refrigerant.

Which car uses 205/65R15 tires?

205/65R15 is the tire specification for the Sagitar. Below is additional information: 1. The new Sagitar has abandoned the individuality and sportiness of the older model, adopting a distinctive family-style design. The overall appearance is elegant and steady, with smooth body lines and fine attention to detail. The car measures 4544mm in length, 1760mm in width, and 1461mm in height, with a wheelbase of 2731mm. 2. In the specification 205/65R15, 205 indicates the tire width of 205mm; 65 represents the aspect ratio of 65%; R stands for radial tire construction, and 15 denotes the wheel diameter of 15 inches. 3. Tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and high and low temperatures during operation. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning ability, along with high wear resistance and flex resistance, as well as low rolling resistance and heat generation.

How long does it take to charge the Wuling Hongguang Mini Macaron?

Wuling Hongguang Mini's Relaxed and Comfort models take 6.5 hours to charge, while the Enjoy model takes 9 hours due to its higher battery capacity. The Wuling Hongguang Mini should be charged when the battery level drops below 30%. A full charge allows the car to drive up to 100 kilometers without any issues. The high-end model has an official range of 170 kilometers as per the Ministry of Industry and Information Technology, and in practice, it can drive between 120 to 140 kilometers on a full charge. Additional information: 1. Motor: The Wuling Hongguang Mini's motor has a maximum power of 20kW and a maximum torque of 85 Nm. The car uses lithium-ion batteries across all models, which are more durable and have higher energy density. The front suspension is a MacPherson independent suspension, and the rear suspension is a multi-link non-independent suspension. 2. Overview: The Wuling Hongguang Mini has a wheelbase of 1940 mm, with length, width, and height dimensions of 2917 mm, 1493 mm, and 1621 mm respectively. It is a 3-door, 4-seater car with a curb weight of around 700 kg, making it lightweight and agile.

What are the symptoms of faulty ignition wires in a car?

Engine operation becomes unstable or experiences shaking. Additional details are as follows:1. Misfires in single or multiple cylinders, or intermittent faults: This may occur when individual ignition wires have quality issues leading to poor conductivity or resistance changes.2. Abnormal ignition, resulting in weak engine acceleration, overheating, or poor acceleration: During use, if the ignition wires' conductivity weakens and internal resistance increases, the spark intensity provided to the spark plugs decreases, leading to weak ignition and incomplete combustion.3. Potential damage to other components: 'Leakage' caused by quality issues or other faults may puncture other components, potentially causing short circuits.4. Risk of fire: Leakage, due to quality issues or prolonged usage leading to overheating, may cause spontaneous combustion or fire hazards.

Is the Haval H6 warranty 5 years or 3 years?

According to the Haval H6 service manual, the quality assurance period for the Haval H6 model is 36 months or 60,000 kilometers, whichever comes first. The three-guarantee validity period is 24 months or 50,000 kilometers, whichever comes first. Additionally, value-added services can be purchased to extend the warranty for certain components, indicating that Haval's after-sales service is quite good. Below is the relevant information: 1. Notes: Although the car has a warranty period, not all repair costs will be waived. This depends on the free items specified by the manufacturer during the warranty period. If these items need repair, they will be free; if other components require repair, the cost may have to be borne by the owner. 2. Three-guarantee: The three-guarantee validity period mainly refers to the three guarantees for automobiles, which are repair, replacement, and refund. However, it's important to remember a few key points. Within 60 days of purchase or within 3,000 kilometers of driving, if there are issues with the main components of the engine or transmission, consumers can have the engine or transmission replaced for free.

What does it mean when the ABS warning light comes on in a car?

When a car displays the ABS warning light, it indicates a malfunction in the vehicle's anti-lock braking system. If the wheels lock up during emergency braking, the vehicle may skid uncontrollably, making it difficult for the driver to slow down or adjust the vehicle's trajectory, posing significant safety risks. There are several states in which the ABS light may illuminate, each with different causes and solutions, as detailed below: State 1: ABS warning light stays on continuously (most common). Cause 1: The ABS speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle's speed or the wheel's slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt from the speed sensor and adjust the gap between the speed sensor and the signal ring to restore normal function. Cause 2: Poor signal due to loose connections between system wires or poor contact in the ABS relay, leading to system failure. Solution: Check the wire connections and reconnect any loose ones. State 2: ABS warning light intermittently illuminates but turns off during acceleration. Cause: When multiple vehicle electrical devices are in use, the battery voltage drops below 10.5V. The ABS warning light turns off as the engine speed increases and the voltage rises. This may also occur if the ABS system's power supply voltage is too low due to poor wire contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light stays on after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body; loose wiring connections in the ABS hydraulic valve body; ABS computer malfunction. Solution: Loosen and then retighten the grounding screw on the hydraulic valve body, cleaning the contact surface if necessary; check if the connector gap has widened; replace the ABS or ABS/ASR computer. State 4: ABS warning light comes on during high-speed driving. Cause: At high speeds, the ABS computer detects a significant discrepancy between the rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: Start the engine, press the brake pedal, and use a finger to push the brake switch linkage all the way down. Then release the brake pedal to complete the self-setting position; replace the brake light switch if necessary.
