Possible water leak locations?

[nomoremrriceguy]

Kinda stumped on where my cars leaking from, it's been raining pretty hard the last couple days and every morning I check inside the car theres a huge puddle of water behind the drivers seat on the floor and the passenger side is wet but nothing like the drivers side, I had to sponge up the water for a good half an hour. I have a sun roof and a trunk with holes from removing the wing but i sprayed both of them with a hose and I didnt see any leak

I had my taillights replaced and the weather seal looks like it should be refreshed but also no leak? I feel like it's the tail lights but can water build up inside the cab if the tail lights aren't sealed?

Side rear windows or the sunroof drains are leaking inside the chassis.

Side rear windows or the sunroof drains are leaking inside the chassis. I have a hunch that its the sunroof drains but how do you access them? I took off the a pillar cover and I see the drain hose but I can actually access it because it's stuck behind the a pillar

EDIT: front drains are fine, both rears are leaking, how do you remove the rear interior quater panel? it seems like its secured by a screw or something but I don't wanna force it and break clips

They should be snapped into place and with a solid pull come free.

Are they leaking at the sunroof or in the tubing somewhere along the line?

on an s13 they come down the B pillar then go into the sills.

on an s13 they come down the B pillar then go into the sills. where are the drain holes though? I can push the hose down into the b pillar but I have no idea where it's coming out, do I look in the trunk?

When you figure out how to access them weed wanker string works well to clean them out!

UPDATE: Turns out for some stupid fuckin reason the previous owner left the hoses intact inside the B pillars, but he just left them unconnected... I took off the interior panels and reconnected the hoses and secured them and voila! everything drains properly and now my interior wont turn into a lake after it rains
