When it is a torrential rain and lots of water on the road it just as if someone turned on a valve and the water just pours in. I have learned it is probably my cabin filter and the grommet around the drain hole but I can't find the drain. Anyone with photos to show where the drain is. I got lots of leaves and debris out of the cavity under the filter and there was an inch of standing water there so I know the drain is stopped up.

Any help would be deeply appreciated.

Here ya go, friend (not my video, btw.)


There are a couple of grommets at the bottom, and that's where the leaves get stuck and pool up the water.

There are also reports that the clips that hold the cabin filter cover in place near the windshield could also be the cause of the water.

Hope that helps!

 

^ This. Came home last weekend from a tux fitting, and when stopping for a red light a waterfall under my glovebox announced my first round of "plugged cowl grommet syndrome" as I now call it. It's a serious "WTF" moment when it first happens, I know.

Easy to fix, I knew of the issue others have had with it, and now knowing that it most certainly can (and did) happen to me, I just stay on top of it and clean out the cowl drains every time I was the car. I have no garage\covered parking, so the debris is guaranteed to end up in there and plugging up the drains. It takes me less than 10 mins to clean out the drains\cowl area now.
