What is the reason for the flashing AC light in Toyota Reiz?

[VonHannah]

The possible reason for the flashing AC light in Reiz is the tripping of the compressor protection device. Excessive refrigerant: Solution: Appropriately reduce the amount of refrigerant. Poor heat dissipation: Solution: Check if there is dust or dirt on the condenser pipe and clean the condenser. Blocked pipeline system: Solution: Refer to the pressure gauge to diagnose and resolve the issue, then reprocess the system. Dust or scale buildup on the evaporator or filter, leading to reduced airflow and imbalance in system pressure and temperature. Solution: Clean the evaporator or filter: When there is a lack of refrigerant, the compressor exhaust temperature will overheat, causing the overload protection switch to trip: Solution: Add refrigerant promptly.
