Door Drain Holes

Went to open the passenger side rear door on my TRD Sport and notice a sloshing sound. So I assumed the door drains were clogged, I've had this happened with previous vehicles, no big deal. I then noticed that the drain holes had plastic plugs, pull them out and out came about a gallon of water. I can't reason why Toyota would plug these holes. Has anyone had this happen? I think i'll just pull the other door plugs so the door can a least drain naturally.

 

Mine has those plugs in the door drains as well. Should they have been removed during PDI by the dealer?

 

I remember seeing these too on my '25. Are they to keep the doors 'square' when they close?

 

My '24 Sport has them as well.

 

I don’t have water in my doors…so no need to pull them. At least I’ll know how to drain the doors if I drive underwater.

 

My wife's '21 Corolla had these and I removed them after reading a similar thread on ToyotaNation. No issues 4.5 years later.

I'm not sure what I'll do when my 4th gen arrives..... leave them in? Pull them out?

 

They are called dust covers. I only know this because I work at a Toyota Assembly Plant and was on the door line a few years ago. They are suppose to be there.

 

Same issue with mine, slosh slosh slosh..WTF, oh drain plugs.
Thought it was just me

 

Thanks for sharing the info Steve.

 

I gave a very close-up look at the plugs in my doors today. The plug itself is shaped like a squarish half-circle (squircle?), kind of like a USB-B plug you would use for a printer.

The plugs obstruct about 2/3 of the drain hole diameter (which is more or less circular) but they do leave about a 1.5-2.0mm gap for water to drain out. So in theory they don't interfere with draining rainwater.
