Why does the car air conditioner suddenly stop responding?
2 Answers
Here are the reasons why the air conditioner does not respond when turned on: 1. Power issues: The power is not properly connected or there is no electricity, the power socket has poor contact, or the power cord is too thin or aged. Low power voltage. Starting voltage for fixed-frequency air conditioners: 187V, voltage fluctuation range: 198-242V. Starting voltage for inverter air conditioners: 156V, voltage fluctuation range: 176-264V. 2. Remote control issues: The receiver is broken or damp, preventing normal operation. The remote control mode is incorrect, or the temperature setting does not meet the startup conditions. When cooling, the set temperature should be lower than the indoor temperature; when heating, the set temperature should be higher than the indoor temperature. Low battery in the remote control can result in a short remote distance or inability to control.
Having driven for decades, when the AC suddenly stops working, it's usually due to a blown fuse or poor button contact. I typically start by checking the fuse box under the dashboard and try replacing it with a spare fuse. If that doesn't work, I then check if the cabin air filter is clogged, or if there's an issue with the compressor or refrigerant system. A broken AC in the sweltering summer heat is unbearable, so I remind everyone not to delay—check the simple fixes yourself, but if you can't solve it, get to a professional repair shop ASAP to avoid sweating and distraction on the road. Remember to pop the hood monthly to check for anything unusual, and regular maintenance can prevent many headaches. A car is like an old friend—it needs careful attention.
