Where do the rear sunroof drains go to on a w124?

[jbach36]

I had water in my car for the first time ever about a week ago. The front A pillar drain plug was clogged so that was a simple matter of taking off the drain plug at the bottom of the car and cleaning it.

I thought that fixed my problem, but turns out some water is still coming in. Not sure if some is still coming in through the A pillar but where are the drain plugs for the rear under the car? Doesn't the water go down the B pillars to somewhere? I want to see if those are dirty and blocking water from exiting. It's possible the water coming in now is through the rear B pillar, leaking onto the passenger side rear footwell area and slowly coming forward to the front footwell area when I go down hills.

Someone previously said there might be a problem with the A pillar drain tube itself. Not sure how that could be a problem because when we put water down there at the top, water comes out the bottom now that I cleaned the drainplug out.

Thanks

the rear sunroof drains go through the C pillars and end up behind the rear bumpers on the sides of the car right next to the air vents.

if you remove the carpet panel from the inside of the trunk you will see them. To unclog them you will have to remove the rear bumper or at least loosen it away from the sides of the car.

I don't know where the water is coming in from, front or rear drains. Being that the rear drain is so hard to get to, I guess I'll have to pour water down from the top of the rear part of the sunroof and watch to see if it comes out near the bumper. That will save me having to loosen the bumper.

Not sure who asked but pictures of rear driver's side sunroof drain hose attached.

Drain hose very flexible

Red primer was to coat some bare metal exposed by body shop repair of that fender.

Metal tube comes down from sunroof motor housing area. Not sure of purpose, haven't looked it up.

Coiled wire bundle used to go to telephone smarts.

The metal tube is to accomodate the sunroof mechanism cable.
