Ticking in HVAC system

Hi there,

Have a '98 ML 320 and am working on the HVAC system at present. There is a ticking sound in the center of the dashboard right behind the center console that disappears everytime you adjust the temp control to the center white line. Is there a motorized damper controlling air flow behind the center vents? Any help is appreciated. Thanks.
