Wind seeping in through driver's side door?

Last night, I went for a drive on the 405 and noticed a cool breeze sweeping across my leg and figured that the blower must've been on. However, since I've had the valve cover gasket issue, I've been turning off my blower every time I get in the car. I moved my free hand around the driver's foot well and noticed that the air was coming from between door and the plastic to the left of the trunk release button (in the car, not on the remote or on the trunk). I put my hand in the seam and that seems to be where it's coming from. I've sprayed this area from the outside with a pressure washer before, and no water got through.

Any suggestions on this one? Any help is greatly appreciated.

There are a few areas that could cause this symptom. But first thing I would check would be the vapor barriers behind the door panel. I know you mentioned that you've sprayed it with a pressure washer. But in fact a pressure washer is not a good tool to use to locate water leaks simply because the pressure is high, but the volume of water is low. If the vapor barrier is in tact, then you'll need to check the integrity of the seal on the drivers side, but unlikely.

Good Luck!

For sure, man. Thanks for the advice - I'll look into this more after my valve cover gasket fix :C

From the 415? I am, too. I cruise the 280 to Krispy Kreme quite often.

Ditto...that was my first thought...I'd check just to be sure. Although the OP's complaint wasn't wind "noise"...but rather air intrusion...I'd still check the rubber jack pad that would be located in the area where the air seems to be coming from:

check to see if you've lost your rubber jack pad (indicated by yellow arrow in pic below from owners manual)..there are a total of 4 pads...1 at each corner beneath the rocker panel
