Nor I can't stand it neither drivers within half a mile from my car. Driver side power window makes horrible noise when operated (no matter up or down - at every moment). Took off door trim, put my hand in every hole, moved every details - no change. I think it could be the front guide (???) but as far as I could see it's velour or something. I checked also those terrible outer pins that scratched my window. No change. What could make those screaming-like noises?
