Why does the Lavida's air conditioning not cool when parked?
3 Answers
Specific reasons are as follows: 1. Abnormal resistance value of the outdoor temperature sensor: The air conditioning system relies on signals from this sensor to regulate temperature. 2. Excessive impurities in the refrigerant and refrigeration oil: This can clog the filter screen of the strainer, reducing cooling efficiency, increasing resistance, and decreasing the flow of refrigerant to the expansion valve. 3. Insufficient refrigerant (Freon): Since refrigerant can evaporate over time, air conditioning systems used for three to four years may require a refrigerant recharge. 4. Issues with the dryer: The refrigeration system of a car's air conditioning includes a dryer, whose main function is to absorb moisture from the refrigerant and prevent excessive moisture from reducing cooling capacity. 5. Loose compressor drive belt: Alternatively, the condenser's heat dissipation capability may have declined, leading to reduced air conditioning cooling performance.
I've been driving a Volkswagen for over ten years. It's not uncommon for the Lavida's air conditioning to not cool properly when idling, often due to insufficient compressor power at idle, especially if the AC system is worn or there's refrigerant leakage. Once during summer while waiting at a traffic light, I encountered this issue where the compressor clutch didn't engage—the fan was running but no cool air came out. Later inspection revealed it was caused by a loose and aged compressor belt, which was fixed by replacing it with a new one. When the AC isn't cooling at idle, don't keep it running as it wastes fuel and wears out components. Instead, I recommend turning off the engine and opening windows for ventilation—it's economical and safer. Regular maintenance checks on the compressor and refrigerant levels can save you from costly repairs, especially for family cars like the Lavida where minor issues are often overlooked. Now, I've made it a habit to turn off the AC when parked, which actually extends component lifespan.
As a user who enjoys tinkering with car equipment, the issue with the Lavida's parking air conditioning failure might be due to electrical system problems, such as relay malfunctions or sensor misreporting idle status without sending signals. Voltage instability when the car is parked can trigger the protection mechanism, causing the compressor to stop working. I've used an OBD tool to check error codes, which is quite handy for identifying the root cause. I recommend Lavida owners to check for loose fuses and wiring connectors themselves—it's cost-effective and quick. This incident made me reflect on how modern car designs consider parking energy efficiency thoroughly but may also affect comfort due to minor faults. Expanding on this, new energy vehicles don't have this issue, as their air conditioning can still operate efficiently at idle, reminding us that paying attention to system health while driving can prevent major repairs.
