Hello, it could be something within the door or in the body. I've seen loose bolts or accidental debris left in during manufacturing, and also perhaps a fastener has come loose inside a panel. Have a technician near you troubleshoot to narrow down the location and then find the source! Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
