I have a water leak that is showing in the passenger A-pillar where the headliner meets the A-pillar interior panel. I pulled down the corner of the headliner above the passenger seat but could not replicate the leak by pouring water over any part of the windshield, roof, sunroof etc... I confirmed the front sunroof drains are draining behind the front tires but I cannot see the rear drain holes that I know exist on other Acura models. Does the 2006 MDX have rear sunroof drains? I've also applied windshield gasket silicone around the top and sides of the windshield but no help there. Can anyone point me in the right direction here? Is there a way for the roof rails to cause leaks? What about the sunroof visor?

Thank you anyone for the help.
