- Low Refrigerant Level:
- Check the refrigerant level in your AC system. If the refrigerant level is low, it will affect the cooling capacity of your AC and cause it to stop working completely.
- Faulty AC Compressor:
- The AC compressor is responsible for circulating the refrigerant throughout the system. If the AC compressor fails, the AC system will not be able to function properly.
- Faulty Condenser:
- The condenser is responsible for dissipating heat from the refrigerant. If the condenser is damaged or blocked, it will affect the cooling capacity of the AC and cause it to stop working.
- Faulty Expansion Valve:
- The expansion valve regulates the flow of refrigerant into the evaporator. If the expansion valve fails, it can cause the AC to stop working properly.
- Electrical Issues:
- Check the electrical connections and wiring related to the AC system. Any loose connections or faulty wiring can disrupt the power supply to the AC compressor and other components, causing the AC to malfunction or stop working entirely.
Since the AC was working on the high setting, we can safely assume that the compressor is still functional. So the most likely cause is a refrigerant leak.
However, diagnosing and fixing AC issues can be complex and may require specialized tools and expertise. If you are not familiar with automotive repair or AC systems, it's best to consult with a qualified mechanic or an auto repair shop to diagnose the exact cause of the problem and get it fixed properly.
