My interior C pillar-drivers side seems to be leaking water, it's drenched all along the top edge of my rear window, beginning from the C window going towards the front of the car...
Wondering what it might be from, and what are possible fixes?
Dealership required/necessary?

 

Pull the headliner down the sunroof drain most likely is disconnected.

 

I agree, I had the same problem but the water was running down my A-pillar. I reconnected the drain hose but a few weeks later it discinnected again so I put a zip-tie around it. So far so dry.

 

Okay, tried getting it down today...Had problems with one clip refusing to come loose in the C pillar that I wanted to look at...And now it won't pop back into place, probably broke a clip while trying to take it out. I might take it to the dealership and see if they can take a look/pop it out. Out of curiosity, about how much would a new headliner run me? I got a quote from a shop that does them, but that's just to re-do the covering for about 250, in suede, or whatever i'd like. Since it has been wet from the rain, I kind of want to replace the whole thing. Any ideas?

Also have some water coming in from somewhere around the rear wiper...seems that one of the gaskets around it is ripped. I know it's from the rear wiper, because I took apart the plastic on the trunk lid and there was a water trail on the inside of the round part (where the wiper motor is)
