This is my first post. Trying this out. So I have a 2007 Acura TL. And this recently has been happening when it rains, the driver side pillar where is says Air bag. It leaks. Does anyone know what might cuase this and how to fix it. This you so much!

 

MINE DOES TOO!

Also want to know how to fix this.. New rubber door seal perhaps?

 

 

Check your sunroof drain tubes and make sure they are draining properly, there are 2 on the front (one on each side) and 2 in the rear (one on each side). Open your sunroof and look in the corner and you should se a small hole on the fronts. The rear you won't be able to see but if you pour a little water in the sunroof housing with the rear of car down hill you should see water drain from behind the rear tire. If they don't drain use dome compressed air to blow them out.

 

I have the same issue with my 04 TL but it's on my passenger A-pillar. I checked the sunroof drain tubes and poured water into them. The drains are not clogged and they are draining properly. I think its the rubber sealing on the door frame that needs to be replaced. Try to see if thats your issue.
