A/C cooling efficiency is reduced; leaves, insects and dust may have accumulated on the heat-exchange surfaces. ^[1]

The manual explains that deposits on the front surfaces can obstruct airflow and reduce cooling performance. ^[1]

Inspect the radiator and condenser surfaces according to the manual; work inside the refrigeration system must be left to a qualified service provider. ^[1]

Clear surface blockages and retest; if cooling remains insufficient, have the system inspected and repaired. Do not directly conclude that the compressor is damaged or add refrigerant without diagnosis. ^[1]

Only applies to the BYD SEAL configuration in the source; model year unconfirmed; the vehicle model database is empty and no model is linked. Do not extend to other models. Scope: unknown ^[1]
