It could be getting past your window seal.

There are small drain holes in the bottom of the door which you can unbung to let the water out. I had this prob with the heavy rain we had a few months back, but now the holes are cleared I am slosh-free.

Your body drain holes are blocked
just beside the rear jacking point where the bottom sheet metal and the side of the car sheet metal come together, there are two drain holes they just need a poke and the tide will soon go out!

Check the softop drains near the seatbelt towers for blockages. That will stop water getting into the sills in the first place. You will still need to clear the drains in the sill like lowmiata suggested to drain the water thats in there now.

I agree with lowmiata



mine did the same thing.

it will be the body drain holes mate!

Oh yes, now I remember. The holes I un-bunged were in the body, not in the door.

but its still a good idea to make sure your door holes are empty to as the water that runs down your window goes out these holes at the bottom

and for a door its usually where the rust starts, you only have to look at the next kingswood that goes past to see what happens!

Not only that, but water in your doors can ruin your speakers too.

Don't ask me how I know that.

When in a carpark once, I noticed a swooshing sound when opening the doors of a friend's 323. "Did you hear that?"

Me, thinking that somehow water is trapped in the door, checks the drain holes. Some monkey had stuck some bits of foam there to seal them up!?

I yanked the foam and water dribbled out for a good 5min

If my memory serves me correctly, there was a factory service bulletin where the drain holes were drilled larger.

i think the miata.net has a link.

Here is a link to an early service bulletin for the drain holes. It includes a diagram that should help you. Included in the link is a futher link to some photos, as shown below.

I unplugged mine about 2-3 mths ago after some heavy rain...... I had to unplug them again yesterday

just wanted to say thanks to smurf, lowmiata, jules and everyone for telling us n00bs about these drain holes.. never new they existed, and i only started hearing the swooooosh in the panel a couple of days ago!.. (bloody sydney rain )

just went out on the driveway with a baby little flat head screwdriver and unplugged all 8 .. the amount of water that came out the drivers side was AMAZING.. as soon as it cleared i was soaked!.. thanks heaps.. my car probably just gained 2kw talk about weight reduction!!

Maybe your rain rail drains (for the roof) are blocked up then.

The soft top drains are located eiher side of the roof just behind the seats. The drain tubes exit in front of the rear wheel wells.

ummmm, I think I may have mentioned something about that in the 4th post of the thread JBT. If the soft top drains are blocked then water may find it's way into the sills, cabin and or boot

You may very well have Garry.......just repeating this as no attempt seems to have been made to check them, he now has water inside the car and nobody seems to have mentioned where the soft top drains exit the car.
