Why is the Land Rover Evoque air conditioning not cooling?
2 Answers
Common reasons for car air conditioning not cooling are likely due to minor refrigerant leakage or excessive refrigerant. Here are solutions for car air conditioning refrigerant issues: 1. Minor refrigerant leakage: This can be observed through the sight glass on the dryer tank. During normal operation, if continuous slow bubbles appear in the sight glass, it indicates insufficient refrigerant. If obvious bubble flipping occurs, it means severe refrigerant shortage. The solution is to add refrigerant, but note: if adding from the low-pressure side, never invert the refrigerant bottle; if adding from the high-pressure side, never start the engine. 2. Excessive refrigerant: Also observable through the sight glass on the dryer tank. If no bubbles are visible during operation and none appear after compressor shutdown, it confirms excessive refrigerant. If excessive pressurized cooling oil is present, somewhat turbid bubbles will be visible during normal operation. If refrigerant is indeed excessive, it can be slowly released from the low-pressure side maintenance port of the air conditioning system.
I've encountered the issue of the Land Rover Evoque's air conditioning not cooling several times, and there are many potential problems. The most common one is insufficient refrigerant, which might slowly leak after a few years of use, requiring a top-up or checking for leaks. If the AC compressor fails, it’s a big problem—the component responsible for compressing the refrigerant stops working, and the car won’t cool at all. A dirty condenser is also troublesome, as dust buildup blocks heat dissipation, and if the fan doesn’t spin or stops working, it gets worse. Electronic system failures are common in high-end cars; a faulty temperature sensor can mislead the AC into misjudging the temperature, preventing it from activating the cooling mode. Additionally, if the cabin air filter isn’t replaced regularly, it can get clogged, reducing airflow and preventing cold air from blowing out. I recommend regularly checking the refrigerant pressure, cleaning the front part of the condenser, and avoiding prolonged idling in high summer temperatures to reduce strain. If you notice the AC isn’t cooling, take it to a professional shop immediately—don’t try DIY fixes—it’s safer and more convenient. Land Rover parts are expensive, so timely repairs can prevent minor issues from turning into major ones.
