Water sloshing in door


Recommended Posts

Hi everyone driving home in my 2019 Corolla last night and when i braked or pulled away i could hear water sloshing inside the door so i pulled out the dust cover bung under the door and about 0.5L of water drained from the drain hole, i then removed all 3 bungs and cleaned them and placed them back in the door i was wondering if this is a common issue as i have read that sometimes the front bung is removed completely to allow water to drain easier any help or opinions would be happly recieved. Thanks

Ps talking to dealer seems a waste of time

This was covered in a previous thread - and removing the bung is a recomendation from the Car Care Nut on You Tube. It sounds like it's best to leave the bung out to let the water drain away.

Thanks for the link dont know why it should just effect american models though as somebody suggested

I dont know if they are or not, part of the forum link which Chris Nutt sent, a comment is made that it only effects american models but that seems to be wrong i was hoping somebody else has had the same experience dealer just pleads ignorance about the issue

I dont think anything ive posted could be seen as a complaint but it depends on your definition of a complaint i just asked a question on the forum.

I tend to think you were reading something into Roy`s post that wasn`t intended. He was actually just having a wee dig at some dealers and the reheubikd spiel that they churn out.

I have permanently removed the rearmost bung from every door.  When I removed the one from the drivers door a brief trickle of water came out. It wasn't much but if the door interior never dried out it wouldn't be long before corrosion starts.

Thank you for this information!

I watch the Car Care Nut channel regularly and reviewed which dust plugs were installed. The car already had the plugs specified in the bulletin removed (published in the last message of that thread). Nonetheless, I think water or humidity still remains within the door panels, because after I close the windows, you can see water smeared along the exterior face of the crystal. That could be as well due to the quality of the crystal seals, that probably allows water to punch through or be stored within the seal after rain or washing the car, and not only due to water being unable to drain off...

I'll try to remove all the plugs and see if this issue reduces or maintains itself.

Gérard, interesting.  I removed mine, didn't bother the dealer.  

Water and metal are a definite combination that will produce rust. As sure as the sun rises in the sky. And anything you can do to keep them apart is better than doing nothing.

I have just looked at several new models, they all have those bungs in the door. In my mind you must have somewhere for the water to go, the scraper seal at the top of the door is not waterproof, water DOES get into the door and must be allowed out, does the bung have a hole in did anyone notice? Will take a look at my Corolla later, I have never heard water sloshing around in my car door

When i removed them they were very muddy and clogged there is not a hole as such its a couple of very small slots inside clearly to allow water to escape but for something designed to keep dirt out mine were clogged with dirt! Perhaps it was doing its job too well also it was the passenger side which probably pulls more dirt from the kerb side of the road as you go through puddles etc now ive cleaned them and tested with several watering cans of water i will see how they last and if it happens again. Have taken a couple of pics as best i can hope they show the route of the water

I believe these are to be removed completely prior to delivery when cars were new. The reason why they had been installed by the manufacturer are because the doors of all cars gets some sort of wax coating inside for rust protection and this thing is actually dripping out from there when the car is new and coating hasn’t been hardened enough. On white cars is much easier to spot. 👍

I'm sure this topic came up before and someone posted a Toyota bulletin about it? It showed which plugs to leave in and which to remove ...
