More wet carpet questions

[TsO346]

Hey guys, been lurking this site the past couple of years since owning my X5 and gotta say that this forum has been extremely helpful in resolving many issues. So much so that I never felt the need to register really, lol. But I finally did and I have question… does anybody have photos on the interior floor without the carpets? I couldn’t find anything on google images. Right now my rear carpet is wet where the middle hump is. Last time my truck was at the shop, I asked the guys to blow some compressed air into the drain lines but nothing came out. I’m gonna get some weed wacker line and push in there and see if that dislodges anything but I’m curious to see the layout without the carpet in place to hopefully see where it could be leaking from exactly. I’m not ready to remove everything to rip my own carpet out yet unless I knew for sure I’d be able to fix the issue right then and there. Thanks
