Figure this one out...

The other day I'm crusing at 80mph on the freeway and notice some wind on my left arm despite the fact that my sunroof and windows are all closed. I place my hand near the wind and discover that a slight breeze is coming from the interior door handle. The breeze gets stronger at higher speeds.

How the fuck is air getting through my interior door handle and why is it flowing inwards at a 90o angle?

I can't say I mind...kinda refreshing.

Air is probably getting by your weatherstripping in the doors and then building up at high pressure inside the door itself and being forced out anywhere it can.

that happens in my car too. no water or anything gets in so i don't mind it.

I agree with what Ken said, and it happens in my car too. It's a motherfuck without a working blower motor (no heat)

Sounds like a fairly common issue.....my '89 325i has the same problem. I really don't consider it a big deal since its just a little air. No water makes its way in (raining or during a wash) so I just let it be. It did catch me off guard the first time I noticed it.

Eric, I think your car is trash and you should send it to me... ;)

im trying to figure out why this was not posted in the tech section.

My M3 does it, even with the whole inside of the door covered in Dynamat extreme, it still happens!!

[nando]

your cars are all broken, mine doesn't do that at all ;)

[Jhonno]

mine doesnt do it either

[mph]

My 1989 325ix does it too. My 1986 325ic doesn't do it, could it be a year thing?

it's just not an "e30" problem. It happens to most cars.

true story

Does it change with age or more so the distance the car's travelled? Thanks,
