Several factors can cause your Hilux A/C to stop cooling:

Low Refrigerant Freon Levels – A refrigerant leak reduces cooling performance.
Faulty A/C Compressor – If the compressor is damaged o r weak, it wont circulate refrigerant properly.
Clogged Cabin Air Filter – A dirty filter restricts airflow, making the A/C feel weak.
Electrical Issues – A faulty relay, fuse, o r wiring problem can stop the A/C from working.
Malfunctioning Expansion Valve – This valve regulates refrigerant flow if blocked, cooling will be affected.
Damaged Blower Motor – If the fan isn’t working properly, air won’t circulate well.
Condenser Blockage o r Damage – Dirt, debris, o r damage to the condenser reduces heat dissipation, making the A/C less effective.

If your A/C stops cooling, checking these components can help diagnose the problem.
