A/C cooling efficiency has decreased, with visible debris on the front heat-exchange surfaces.
BYD ATTO 3: Insufficient A/C cooling with leaves or dust on heat-exchange surfaces
Symptoms
- A/C cooling efficiency has decreased, with visible debris on the front heat-exchange surfaces. [1]
Possible causes
- The manual explicitly states that deposits on the radiator and condenser surfaces block airflow and reduce cooling performance. [1]
Checks
- Check the radiator and condenser surfaces for blockages; refer internal refrigerant system inspection and repair to a service provider. [1]
What to do
- Clear surface blockages and retest; this does not justify directly replacing the compressor or adding refrigerant without diagnosis. [1]
Applicability and limits
- Only applies to the corresponding ATTO 3 configuration in the New Zealand English-language owner's manual; the manual date is not treated as an applicable model year. No actual vehicle model has been linked. Do not extend to vehicles with the same model name, other powertrains or other markets. Scope: unknown [1]
- Only applies to the specific configuration in the cited manual; do not assume applicability to all vehicles with the same model name.
