Mazda TSB #07-004-22
2020 Mazda MAZDA3
Affected Component: ELECTRICAL SYSTEM
- Summary
- Some customers may complain that after accelerating in hot weather, the A/C blows warm air for a longer time than other models. This is caused by improper control software of the PCM not allowing the A/C compressor to resume properly after acceleration. To eliminate this concern, the control software of the PCM has been modified.
