Hey Everyone, I am trying to figure out if the sun roof drain tube is connected on my wife's 08 Sport. I want to lower the headliner down without breaking anything.

I need to take the A-pillar off but it has the air bag in it... obviously i dont want to F that up at all. I am going to disconnect the battery to start with but is there anything special that needs to be done there?

As for the headliner then, I should be able to pull it down a bit after i take off the visor and some other things. If you have any tips or suggestions PLEASE let me know. I want to get this done after work this week so I am trying to stream line this as best as possible. Any suggestions are appreciated, except to take it to a shop.
