What are the reasons for the newly purchased car's air conditioner not cooling?
2 Answers
Here are the reasons why the newly purchased car's air conditioner is not cooling: 1. Internal damage: Severe internal wear of the compressor leads to its inability to function properly. 2. Oil stains: Oil stains at the connections or seams indicate refrigerant leakage, and the relevant parts should be reinforced or replaced. 3. Circuit system failure: It is also very common for the car's air conditioner compressor to malfunction due to circuit system issues. You can check if the circuit is unobstructed, inspect the temperature sensor solenoid valve, and other potential faults. 4. The low-pressure gauge reading is much lower than normal: The surface temperature of the compressor's suction pipe is lower than usual, appearing damp and cold (commonly known as 'sweating').
I was also quite puzzled when this happened to me the other day—the AC in my brand-new car wasn’t cooling properly. In most cases, poor cooling in a new car is due to operational issues. Many people don’t realize that the A/C button needs to be lit up to be activated. Did you turn the temperature knob to the lowest setting? Is the air vent mode set to blow at the feet? Another possibility is that the refrigerant might have leaked due to vibrations during transport, or the condenser’s fins could be blocked by leftover packaging film that wasn’t fully removed. Occasionally, electronic glitches can also occur—try turning off the engine, waiting five minutes, and restarting it; that might resolve the issue. Last week, my neighbor’s new SUV had the same problem, and it turned out the AC fuse wasn’t properly seated during factory assembly. But don’t try fixing it yourself—just head straight back to the 4S店 and let them check it out. It’s all covered under the new car warranty anyway.
