Vauxhall Signum - Tapping from behind dash on start up - jonny10buds

When I start my Signum there is a tapping sound for about 5 seconds from under the dash on the passenger side, someone has suggested it's the recurculation flap stepper motor, does anyone have experience of this and what's involved in repair? Thanks in advance, John
