The front pillar cover is damp. I need the location of the sunroof drains and any ideas about other possibilities? The water only leaks after a heavy rain, not during normal A/C use. I opened the sunroof and observed water around there. It last rained here 2 days ago. Thank you for your assistance both past and present.

Hello, there are drain tubes all around the sunroof. Usually the interior ceiling has to come down to access them. Most likely the seal for the sunroof is leaking, it's very common. But it's a repair you're going to want to do soon before any water gets to any electronic components. This can reek havoc on the engine computer and other modules. If you have any future problems, ie check engine light, let anyone who does the repairs know about the past water issue.
