Water Pouring out of Rear HVAC controls

[Seattle100]

We got a big downpour last night for the first time in 4 months, and as soon as I started driving afterwards, water POURED out of the rear HVAC controls. I haven't had a chance to tear into the headliner yet and I couldn't find this same problem searching.

Any guesses on where I should start? My roof rack is stock. Nothing aftermarket on the roof as far as I know. I was parked facing slightly uphill, so I doubt it has anything to do with the tailgate/3rd brake light/wind deflector.

I plan to check the sunroof first. After that I can only guess roofrack.

Let me know if you've got any great ideas.

was the sunroof fully closed?


check the sunroof drain tubes for clogging?

Have you had the car since new? I had a roof leak a while back. While removing the b-pillar trim, I noticed the roof had likely been painted at some point from hail damage. One of the feet on the roof rack wasn't tight all the way and was leaking.

Likely the drains to the sunroof . . .

Thanks for the replies.

Turns out it was the sunroof drain, but it wasn't your typical clog. The idiot PO had shoved 2 crappy amps where the factory sub used to be, and while "securing" one of them by wedging it against the body and holding it there with a piece of MDF sheetrock screwed to the flange, he completely pinched off the drain line.

So for posterity, the info I wish I had known:

1. There are 4 drain holes for the sun roof.
2. They drain at each wheel well, so if you pour water in the 4 corners of the sun roof, you should see 4 puddles on the ground.
3. Rear Drivers Side is a bigger hose than then others (at least on mine?), and can be pinched off if you start shoving things behind that panel.
4. If those lines are clogged, it will get in the headliner and pour out of the rear AC/Heater controlls.

All's well now, just in time for the rainy season.
