Normal Operation and Fault Conditions

When the roof opening panel glass closes, it should do so quietly and smoothly. The roof opening panel system is made up of many components that require specific torque specifications and correct installation in order to avoid any NVH concerns. Over time, components may become loose or damaged, fasteners may become loose, sound insulating material may wear out and foreign material may collect in the roof opening panel frame. It is possible that one or more of these conditions may lead to a noise concern in the roof opening panel system.
