This is the outside driver side door window seal of a 2010 Corolla. It has separated and allows water into the door. What is the replacement part actually called to look up or if someone knows about Toyotas and maybe knows a part #. Thanks
The purpose for those is to fill the gap between the metal and your glass. Those won't stop water but just reduce it. They are for cosmetic looks more than a seal.
If water is coming into the car from the door then the water defector behind the door panel is most likely not sealing. It's the plastic sheet stuck to the metal that nobody replaces when they do repairs/mods inside the door. If water is standing in the door and sloshing then the drains are clogged on the bottom of the door.
