Rear Air Vents

[nlee]

Very rarely have passengers in the rear and even rarer around here that's it's hot weather. However, had both this weekend and my passengers were complaining there was no cool air from the rear vents. 

I couldn't get my head around why, tried every setting and auto on the climate control but nothing directed to the back.

I read elsewhere last night that the seat occupancy control of air con (the left hand button on the air con controls) stops air going to the back (also suggests ECO might do the same). I always have that activated as it is usually only me in the car. It makes sense that it wouldn't put air to the rear if there was nobody sat there but I presumed it would work if a rear seat was occupied (it must know for the seat belt warning to work). It seems not, at least not in mine. Anyone else see different behaviour?

Eco Mode cuts the A/C output, In the case of rear vents it will shut them to conserve energy

Pretty sure...

 

If ECO selected, or, No Seat Occupancy Detected then no air to rear vents.

Not sure if you mean this but....

I sort of get the ECO part. I didn't have ECO on but I did have the left hand button active (seat occupancy). However, both rear seats were occupied but there was still no airflow. It seems, at least for me, the seat occupancy works in the front, but regardless of whether there is anyone sat in the back, there is no air flow with this setting active.

It's off now, I doubt it makes a material difference to efficiency.

On my 21 Rav, even on ECO then air will go to the rear vent.

That's strange. I just tried and get air flow to the back when not in ECO and there are folks sitting in one or more seats. Maybe there's another setting somewhere? I need to look properly this weekend.
