Rear passenger air vents not working

[Slucky]

Hi All,

On a Lexus IS250. Have recently noticed and have rear passengers also said that the rear air vents do not blow any air, warm or cold. I have checked that the vents are both open. 

Putting the AC on only blows air in the front and not in the back. Have tried putting Fan mode only and the air vents feel a bit warm. 

Does any one know how the rear air vents work?

Thanks

Does you model/year have the S-Flow option in the heater controls? That option when on can disable airflow to the rear

Hi, 

mines a 2007 model. What’s the S-Flow option?

thanks.

From my handbook (2016 model RC)

"S-FLOW mode
When there are no passengers in the rear seats, airflow can be directed to the
front seats only to reduce the air conditioning effect on the rear seats.
However, depending on both the temperature inside and outside the vehicle, airflow
may be directed to the rear seats even though S-FLOW mode is on to maintain
comfort inside the vehicle.
Press .
The indicator comes on when S-FLOW mode is on.
Press again to resume airflow to the rear seats."

I presume this feature is not available on the later models.

Sorry I meant earlier models. As I don’t see this feature.

Get the codes read, you may have a failed air distribution flap motor...
