W211 E240 2002
Clicking noise behind dash air vents.

My E240 W211 2002, has a regular slowish clicking sound for 5 seconds or so after the temperature control knobs are adjusted. I assume it is one of the linkages or stepping motors, does anyone have any experience in doing the job on a W211?

Stepper motor link is cracked and spinning on shaft of vent flap. Depending on which stepper link, dash removal may be required.
