I have Swift 2011 .. And i have a constant irritating Noise Coming from passenger side door when on the road .. On the motorway as well when above 100 .. and on the Gt road it is constant when at speed .. Opened both front and Back door panels but nothing was out of place or loose .. I also have installed sound dampning sheets but still the noise is there .. Can't understand what to do .. Any suggestions ? .. I have to travel tommorow to Islamabad .. and have a few hours to spare in the morning .. Any good place i can get it checked ??
