What Are the Reasons for a Car Air Conditioner Not Working?
2 Answers
Car air conditioner not working reasons are: 1. Severe internal wear of the compressor; 2. Refrigerant leakage; 3. Circuit system failure. Car air conditioning is the abbreviation for car air conditioning devices, which include refrigeration devices, heating devices, and ventilation devices. Car air conditioning types are: 1. Divided by driving method: independent and non-independent; 2. Divided by air conditioning performance: single-function type and combined heating and cooling type; 3. Divided by control method: manual type and electronically controlled pneumatic regulation; 4. Divided by regulation method: fully automatic regulation and microcomputer-controlled fully automatic regulation.
My car's air conditioning broke down while driving, and it was unbearably hot in the summer. There are many common reasons for this. It could be a refrigerant leak, causing low system pressure and inability to cool; or a compressor failure, with a worn drive belt or broken clutch, resulting in only hot air when the AC is turned on. Blown fuses are also common—once they burn out, the current is cut off. Check the fuse box under the hood for AC-related fuses. A non-functioning fan can also affect cooling efficiency—I’ve encountered stuck blades or a damaged motor before. Turn on the AC and listen for sounds to diagnose. A simple fix: try replacing the fuse yourself. If that doesn’t work, head to a repair shop immediately to avoid dehydration and fatigue during long drives. Regular maintenance, such as topping up refrigerant every two years, can prevent leaks.
