The seal that stops water running down inside the door, what the window slides between.
This bit:
They’re dying on my car and as I’m taking half the doors apart anyway to fix something else I might as well replace it, but my Googling is failing and I’m blowed if I can find the things online anywhere, or even what they’re called.
“Window seals” just seems to give me the side & top seals, is there a specific name for these? I don’t need to replace the whole way round, just the bottom “wiper” ones. And as a bonus: where’s a good place to buy these for a Renault?
