The reasons for the Nissan X-Trail's air conditioning not cooling may include excessive refrigerant, poor heat dissipation, blockage in the pipeline system, dust and scale accumulation on the evaporator or filter, or lack of refrigerant. Below is an introduction to the 2021 VC-Turbo Fashion Edition X-Trail: 1. Powertrain: Equipped with a 1.5L turbocharged 3-cylinder KR15 engine, paired with an 8-speed continuously variable transmission. 2. Body dimensions: Length, width, and height are 4681mm, 1840mm, and 1730mm respectively. The wheelbase is 2706mm. 3. Chassis: The drivetrain is front-wheel drive, with a MacPherson strut front suspension and a multi-link independent rear suspension.
As a veteran X-Trail owner with over a decade of experience, here's my advice when AC stops cooling. Refrigerant leaks are most common - pipe joints tend to degrade and leak, especially in vehicles over five years old. Loose or damaged compressor belts are another frequent issue; pop the hood and listen for abnormal humming sounds. A minor but crucial detail: radiator clogged by willow catkins or insect debris - a water spray can fix this. Electrical faults account for about 30% of cases, like failed pressure switches or blown fuses. Last month when my AC failed, it turned out to be a condenser fan motor replacement costing just 300 yuan. Pro tip: avoid prolonged parking under direct sunlight, and get a comprehensive pre-summer checkup annually.
I've encountered the X-Trail's air conditioning issues several times, and here's my recommended troubleshooting sequence. First, start the vehicle and check if the AC button lights up when set to maximum fan speed - make sure there are no operational mistakes. Second, measure the vent temperature; if airflow is normal but not cool, it's 90% likely due to insufficient refrigerant or compressor failure. Third, feel the high and low pressure pipes - if the temperature difference is too small, it indicates circulation system abnormalities. Fourth, inspect the blower motor and check if the air filter is clogged enough to obstruct ventilation. Finally, examine the electrical circuits, paying special attention to the compressor clutch and AC pressure sensor which are particularly prone to failure. Never attempt DIY repairs on refrigerant lines - professional equipment is required for vacuuming and recharging the system.
