3 Zone Climate

I'm not that concerned about it...just a nit picky thing, but on my GLS with 3 Zone Climate, it seems like no matter what setting it's on, no air comes out of the ceiling vents in the back. You only get ceiling vents with the 3 zone climate package. If anyone has this package, if you could check if your's work, I'd be curious to see if mine have something wrong or it's just designed to not blow enough air or what.

Thanks

The only time you maybe feel it is when it turns on. Other than that, nothing.

Not sure if that's worth bringing it in for, but it's odd.

A gaggle of MB's

Please review your Owner's Manual pgs 131-136 (from memory) - you can also download PDF from mbusa.com from the Owner's Section.

The "roof vents" airflow is linked to the B-pillar vents - and the rear control panel has two air flow buttons that control the for air flow (center/floor vents) and 2nd button for the (B-pillar/roof vents) ... I "think" those air flow buttons might be "deactivated" if using front climate control to control the rear under single zone control - and air flow buttons are active if under rear control - and you can choose airflow - either all air flow center/floor - or all airflow B-pillar/roof - or with both buttons activated air flow is thru ALL.

I know you will work it out... check the manual pages - keep in mind my post tonight is from my memory....keep the beat !
