The process of recharging Freon in a vehicle's air conditioning system is: 1. Evacuate the system by closing the manual valves on the pressure gauge and the high/low pressure manual valves; 2. Connect one end of the hose to the injection valve fitting of the Freon canister; 3. Open the refrigerant canister, loosen the nut on the pressure gauge hose to release some gas, then close it; 4. Open the high-pressure side manual valve and invert the canister; 5. Inject the specified amount of liquid refrigerant, then close the refrigerant injection valve and the high-pressure manual valve. Vehicle air conditioning, also known as automotive air conditioning, is used to regulate and control the temperature, humidity, air cleanliness, and air flow inside the vehicle cabin to an optimal state.

What are the causes of water ingress on the floor of a 2014 Bora's cabin?

Possible causes include rust perforation in the car's chassis, clogged drainage channels, damaged seals, or water accumulation in the sunroof. Here are the detailed explanations: 1. Rust perforation in the chassis: Water can enter through the wheels, so it's necessary to carefully inspect and seal or install protective plates. 2. Clogged drainage channels: The rainwater drainage holes under the front window may be blocked by debris. 3. Damaged seals: During rainy weather, water can seep into the car's floor through the doors. Check the door seals for damage or wear and replace them promptly. 4. Sunroof water accumulation: Prolonged water accumulation in the sunroof can clog the drainage tubes, causing water to flow into the car's floor from the center pillar. Regular inspection and cleaning are essential.

Why Does the Car Alarm Go Off in the Middle of the Night?

Here is the relevant introduction to why the car alarm goes off in the middle of the night: 1. The car door is not closed: The car's anti-theft device detects the opening and closing of the doors. If a door is opened without the car being unlocked, the alarm will assume the car is being broken into and will start sounding. This situation may occur if the door is not tightly closed, and airflow causes it to occasionally open slightly, triggering the alarm. 2. Anti-theft device malfunction: This is a sign of poor quality or long-term lack of maintenance of the anti-theft device. When the car is stationary, internal current disturbances can cause the anti-theft device to give false alarms. 3. Sound or vibration: The anti-theft device detects vibrations. If there are low-frequency sounds or slight ground vibrations, they can also trigger the car alarm. Although humans may not notice these, the anti-theft device's vibration sensor will detect them.
