Summary
Some customers may experience that after starting the engine, the auto A/C blows warm air for about 10 minutes and then blows cool air as desired. This concern occurs when the ambient temperature is within a certain range (approx. 16-25 C / 61-77 F). This is caused by the control software of the Dash-Electrical Supply Unit (Dash-ESU) not being appropriate for this specific situation. To correct this concern, the control software of the Dash-ESU has been modified.
