    Water Drain holes, NA NB Miata

    Alright fellas, I'm aware that there are two drain holes (this is what I call them, I don't know if that's their name, but they drain water, and I'm french, so drain holes it is) positioned behind the top of the seat belt mechanism thingy that go down just behind the doors and out. I clean those out semi-regularly because it seems that a lot of junk gets in there in a season.

    My question is, are there any other holes I am not aware of? I thought there were two more somewhere else but I can't for the life of me figure out where they would be.

    Thanks!

    This isn't so much a part of the exterior, but if you have a/c, also make sure the drain from the evaporator (passenger side footwell) is cleaned out. If not, your passengers will get wet feet when you take hard turns.

    Ignore the writing, but here's a google picture:

    I've got a lot less horsepower - luckily they are Japanese horses - usually in better shape and more motivated.

    These sills should be enlarged, while you're down there, if it hasn't already been done.

    I'm pretty sure there's one in the top door sill too, but I can't find any pictures of it or anyone talking about cleaning that one. Should be just above the corner window? Maybe that was in my civic or something.

    While you're at it, you can clean the two drains that are at the corners of your cowl (at the windshield base). They empty into behind the front fenders. You really should clean behind the fenders as well.

    I got around to doing them today. Thanks everyone for the info. Not very clogged whatsoever. I noticed one was basically bent shut on the rear passenger side, should I be concerned? Should I bother to open it back up?
