Re: Drivers side window makes a thud sound when opening
I have the same problem, and yes not all the time, just have not felt like pulling the panel, I would think it would be the track or a window stop that moves out of posistion from time to time, but I have had the car for over three years and its still intermintent, so I guess it really hasn't bothered me enough yet to look at the cause, let us know what you come up with, if you decide to get into it.
