How do I adjust the drivers side window to tilt in just a bit on the rear top side of the drivers door? I get a wind noise when driving at highway speeds just behind my left ear. If I touch that top rear corner of the window it gets louder.

I would bet you just need to replace the felt guides - they may be worn and allowing the window to move a little.

They look like new. I know that there is an adjustment bolt somewhere that tilts in or out. Does anyone know how to do it?

the "body exterior" .pdf file on this link has full details of how to remove and install/adjust the window - I suggest you download ALL the files and save them on your computer, they are slow to load from the website, but once saved they open and can be viewed very easy

I just got this from another forum and just did the adjustment, it took less than a minute.
1. Look under the lower horizontal part of the door.

2. You will see 4 rubber plugs (2 on each side). Pull out the inner (towards the front) of the two plugs that are on the rear side (closest to the striker plate on the door).

3. Loosen the 10mm (IIRC) nut that is inside that hole.

4. Move the bolt (by placing your 10mm socket over the nut) towards the outboard side of the car and the rear top left edge of the window will move inboard until you get a correct fit with some pressure against the gasket.

5. Tighten the nut.

6. Replace the rubber plug.

Here is a photo of the bolt (stud) that is pressed in to the bottom of the window regulator rear leg, directly above the nut you are looking for. You can see the other (outer) rubber plug just to the left of it. The rubber plug you are looking for is directly under the stud to the front of the rubber plug you can see in this photo:

in the event that it's not the window itself, it might be the seals. i recommend treating them with a Wurth Gummi Flege stick , takes care of any wind noise in my car almost instantly, apply once every 3 to 6 months.

Did it Cure the noise? i have the same issue

I recently purchased a 2000 996 and the wind noise from the drivers side was terrible. At 60 mph I might as well had the window open. I started by making the adjustments mentioned in this write up. My window was way out of adjustment and was not adjusted high enough. It was much better but I still had air noise coming from the mirror area. I couldn't find anything wrong and I didn't want to purchase a new window seal as mine seem pliable and ok. I took some adhesive backed foam and inserted behind the main seal and in the gap with the seal on the top of the door frame. I think the wind was getting in this gap and making the noise. My wind noise is now 98% gone. At this point I would say it is acceptable.

You don't have a picture of where you put the foam, do you? I have been chasing the same noise in the passenger side window of my '99 996 Coupe. It would be worth a try. Thanks!

I had the same issue. While driving I could push from the inside of the seal on the spot where the noise was coming from. When you hit the right spot the noise will decrease or go away. That is the spot you need to insert the foam into the gap. Instead of foam I actually use a piece of dowel covered with heat shrink tubing to get the right size fit. You may need go out and test it and play with the size and location to get it just right.

Actually, the noise was so bad on a trip to the in-laws house today, that I borrowed a 5mm wrench while I was there. My nephew and I went out and adjusted the window again.

Contrary to some advice on this forum (and other forums), if you are under the car door looking up at the adjuster bolts, turning counter-clockwise ("lefty loosey") RAISES the glass. I had time, and was patient, so I marked where it was, turn clockwise, and realized it was lowering the glass. I had counted the turns, so I reversed course to get back to my starting point.

From there I went 5 turns (1/4 turns) on each one, and re-checked it. I did it for a total of 12 one-quarter turns of the wrench (3 full turns of the bolts), and got the window to bury itself in the gap properly, like the driver's side. At that point the rear of the glass had a wider gap than the front, so I added 3 more one-quarter turns to get it relatively even all the way across.

On the ride home, the noise was almost completely gone. So tomorrow I'll go out and give it 2 one-quarter turns on each end until the noise is gone completely, with test drives in between.

I think I have finally gotten this problem licked. Now I just need to get that little sunroof rattle to stop.....

Thanks for the feedback on the foam! Take care.
