I have a 2007 EB Expedition with the power quarter windows. I intermittently have a wind/ vibration noise from the right rear quarter window. It mostly occurs when it is hot, at highway speeds with the air conditioner fan on higher speeds. Needless to say, i am pretty sure it is from the air trying to escape through the window. When it has done it at idle, I can press on the window from the outside and stop the vibration. Opening and closing the window does not change anything. Is there an adjustment to tighten the window so it closes just a little tighter against the weatherstripping?
I don't have the manual for this vehicle yet and I haven't had the pleasure of opening it up, but I did have the passenger quarter window freeze in the open position so I had to pull the power connector to see if it was the switch or motor. But I digress; I didn't see anything that looked like a mechanical adjustment and could only imagine that the motor would need to be shimmed to tighten the closing force. Again, without manuals or actually removing the motor myself put that in the "for what it's worth" catagory.
I did not see any adjustments either when I looked at it. I did not even think of shimming but that that is a good thought. I went ahead and ordered a manual off of ebay and will see if it shows anything different.
