Aircon issue - air flow switch keeps changing.

[Bossman]

Hi all,

Recently realised that the car air flow keeps changing from internal circulation to allowing air from outside to enter and then back to internal circulation. When it is switched to the later, the coolness of the aircon drops. It is normal?

It may be normal for your car. You have to check the manual.

 

For example, Lancer Ex starts in recirculation, but it will automatically switch to fresh air intake when the interior temperature is reached. You have to manually switch it back to recirculation before it stays there. This is with aircon set to Auto speed.
