Cab Wind Noise
Our 95 993 cab produces a good deal of wind noise at the junction of the door windows and the roof. Is this expected or something which naturally occurs in a 15 year old car? Was it this noisy when new? I measured the noise at the top of the window and came up with 100+ dB.
AFAIK, the top (hood in the UK) is original but in seemingly perfect shape but if there is some way to get a better seal (less noisy) I'd sure be interested.
Suggestions? Thanks. Oh, also the manual says something about a wind blocker which I suppose means when the top is retracted. Is there really such a thing? Does it work?

So I need to look for something behind the front seats to see if I have a wind blocker? I think I've looked there a few times w/o seeing anything of interest.
What can I search on to find the thread on how to adjust the windows? I tried a search before posting & didn't find anything relevant. Thanks.

Mine does the same thing. I just thought all cab's had a good deal of wind noise with the top up. I'm going to search for the window alignment posting as well. Here is a picture showing the windscreen.

Reload this Page I eliminated the wind noise from my Cab!
I can't figure out how to cut and paste a thread. Do a search for cab top wind. The sixth thread down is the one you need. It is titled I eliminated the wind noise from my Cab.

I currently have been trying to adjust the slope of the roof at the passenger door window as the window will hit the seal when closing, while the drivers side has full clearance. The passenger side window must be down about a 1/4 inch or so in order to not hit the rubber. I think it has been this way since I bought the car 5 years ago. Recently one of the latching motors broke. I fixed it by turning the gear with the broken teeth in the locking body. Now I cannot get the red light in the center console to go off, plus for some unknown reason the top will not go down once the motors unlatch at the windshield. I have been raising/lowering the forks located at the cab transmission area with some success, (I have found this will alter the amount of wind noise present) but there must be other areas that can be adjusted. Does anyone know if there are other adjustment spots?

I believe you can adjust both the height of the side windows and the angle of them. You have to remove the door panel to do so.
You might also look at the condition of the seals at the windshield and the side of the roof. Some lube -- gummi pflege is really good stuff (if BMW still makes it, if not I believe Wurth has something similar) -- can help restore some life to the seals. They are not cheap to replace.
Mine is reasonably quiet with the roof up, not as quiet as my wife's CLK550, but not ridiculously loud. I replaced the driver's side seal and had the top professionally adjusted three years ago.
My rock band is 105 db onstage. I can hear the radio when I'm driving the car with the top up, and I sure wouldn't hear it at 105 db.

Do a search for cab top wind.
The thread was started by Dudley it's the sixth thread from the top.
It looks like he adjusted the rubber above the windows to seal better and make sure the gap was minimal.
Your check went out Saturday so you shou;d see it tomorrow if you didn't see it today.
