Weep Hole Plugs

Why do they put these in the weep holes at the bottom of the doors? I was wiping down the inside of the door and one popped out. Some water and debris came out so I popped them all out.

You answered your own question. They are weep / drainage holes for any condensation or water from inside the door. They could deffinately be made better, I've popped plenty off while cleaning and they bend and break easily.

I know they are weep holes, I just don't understand why they put the plastic peices in them in the first place.

Years back on my Pontiac G8 GT, it had a problem common among the model, the weep holes in the door were also the holes the push pins went in to hold the weather stripping on the bottom of the door. They were notorious for getting clogged with junk. Every now and then, especially after a lot of rain, I'd hear a sloshing sound in all the doors. I'd have to pull all the weather stripping off the bottoms, which was nasty it was always slimy and dirty, and let the gallons of water that accumulated drain out.

Exactly! Seems like they put these things in so the doors accumulate sludge and rot out!

The doors need to be able to drain and ventilate or you will really see issues. The plastic covers are to prevent bugs and larger debris to gut up in there. It doesn't 100% prevent dirt or mud from accumulating. If you're aware enough, these are a service area by keeping them clean and flushed out.

I took mine out when I bought my 2025 and sprayed a boat load of fluid FIlm into all of the doors in cluding the rear door and the hood. Done it with all of our vehicles usually in the fall while the cars have been dry for a few days. Being in Michigan with all of are snow and salt it really helps keep the rust at bay.

I've taken them out of all my cars for years with no problem. Sometimes I will see the tip of a poly nose from a maple tree sticking out and then I remove it. The plastic thingy just stops bigger debris from coming out and crap can back up in there and stay moist.

Here's a related experience of mine on the same note: The S197 Mustangs had a similar idea that was disastrous but in the firewall. Early on in that generation there were problems with the passenger floorboard and behind the dash getting wet. Turned out some genius engineer designed the firewall to have a void in the middle. There was a gap of a few inches between the wall behind the dash and the wall you see behind the motor with a floor between them. Sort of like a metal fish tank between the dash and motor for some strange reason.

So long story short, there are two drain holes of adequate size on the bottom of each side of the void. BUT in the drain holes are oblong rubber plugs with a little slit for the water to weep out. Well it didn't take very much for leaves, dirt, or whatever to seal those holes shut. When it rained the void would fill with water and it would come in through the cabin filter opening and soak the passenger side carpet.... A LOT.

This happened to me on my 2005 Mustang. I researched it and found the logical and simple permanent solution was to locate and remove the plugs. I swear there was so much water that came out it was like a toilet flushing.... AND a TON of sludge and decaying leaves came out too. It had to be a couple of gallons. I took all the cowling off and flushed it clean. Never had a problem again.
