2014 Lexus RX 350 Rear A/C Question

[RWD88]

Good morning, folks.  I have scoured the internet and have not found the answer I am seeking. Perhaps somebody in Lexus World can assist me.  

The story begins with my '05 Pilot, the Rear A/C has a Filter Screen that needs to be vaccummed at last once a year; otherwise you notice less air out of the vents.

The Dealership never told me this, I found out several years ago about this online; and then I had it out with the dealership about the kind of service they provided.Of course they claimed they do check , but I had pictures of Filter screen to prove otherwise.

Recently, our Lexus rear A/C seems to not be forcing out as much cool air.  Our kids say they do notice it; I am wondering if anybody out there knows if there is a filter screen for the rear AC and it's location?  Or can verify that there isn't a filter screen.

 

Thanks
