Rattling noise in dash

[Richard L S]

My 95 NSX has developed a rattling noise in the dash. It is apparent when the engine is running, even if I'm am not moving. It seems to be in the area of the vent in the dash that I believe is the cabin air temperature sensor and the noise will temporarily stop if I push down on that vent (the one under the ashtray).

Does anyone know what could be causing this?

Thank you in avance for your thoughts.
