Dumb as it may sound, how do I remove the the short air duct on the left side of the air box just above where your right leg rests. Getting this thing out would make changing this actuator simple but mine is solid as a rock. Since I'm dealing with a pinched nerve in my neck I can't get into a position to see what I need to. The actuator is out and I have a new one ready to go back in. Usually you merely squeeze the duct together and it releases but I can't see that working here. Help an old dude out. Thanks.
