Hello all, this is my first post here, I have lurked in the past when I owned an RX400H, but never made an account until now.
I was hoping someone could provide some insight regarding a problem with my 2014 LS. I bought this car a couple months ago, and everything is wonderful....except for water appearing underneath my interior C pillar garnish when it rains. I have provided a picture, (hopefully it works) and would highly appreciate any suggestions as to where this leak could be, or at least how to remove the C pillar garnish (I'm relatively handy, but the Air Bag in there scares me) so I can diagnose it myself.
Thank you in advance!

Thanks, I'll check the drains, then take the garnish off if need be, maybe a drain hose connection is off?
