This was one of three problems that befell me on the same day! My driver door window winder failed - the motor still makes a noise and the glass will only move up or down if I move it by hand. I'm not sure how these things work but since the motor is apparently working is it likely that it's just some detachment within the door. I live in Dubai and main dealer costs are extortionate so I might have to shop on line for parts - any suggestions and also a reliable on-line supplier. Thanks
