I just noticed that air flow from B pillars ducts is very poor in my 2011 LS460L . You hardly feel any air flow, whereas all other ducts, flow is very good. The car does not have rear seat AC. Its still under CPO warranty. Before I make a trip to dealership, can some members verify that is this normal or something is wrong. Both ducts have low flow and are comparable. I mean left and right have same flow. The console ducts have pretty decent air flow.

Thanks in advance for your help

Both mine are working good, but you may want to see if you have any ducts manually closed up front.

I know now if you close a vent, it may not flow to all other vents equally.

Here is a somewhat informative thread touching on this subject matter that I started earlier this summer.
Though it does not get into many specifics, it is briefly spoken about and addressed by caha14.
Hope it helps!

Took it to the local dealer yesterday. They say its normal as the side vents have very limited airflow. I still don't believe it but probably have to live with it.

I also have a 2011 LS460L I'll check mine later today and see how it is. I forget I have those since I'm never in the back!

Where is the b pillar duct?

B pillar is the one between the front and rear door. For rear seat, you have ducts in the center console and on the side pillar. I am talking about these side ducts.
