anyone ever change the actuator on the fresh air intake on the hvac system?

mine is broke on my 2004 gmc seirra with digital duel climate control, it is behind the glove box, I can see it but not sure what it is going to take to change.

thanks for any help.

 

Yes I've changed alot of them. You have to remove: both A-pillar trim,
cluster bezel trim, and Instrument panel. I like to remove the passenger airbag module. There is a metal support brace on the top passenger side with 10mm head bolts that comes off. I remove 7mm head bolts from vent duct and pull it upwards. Reaching through hole where air bag was to reach screws and actuator.

 

thanks for the help!!!!
