My power window driver side kapot. It does not respond though there is sound like motor running. It sound like something snap... then static.Now, what could it be and how much it will cause? I've called up one of the mechanic and he said couls caused RM400++ and i asked if parts from potong shop, cost RM300++.I wld prefer to find parts from potong shop, it's not engine parts.Comments pls...Tx
