Hi I have a 2003 Trailblazer (North Face Edition) and my front vents are not blowing. I do not hear any clicking noise at all, I've tried to pull the fuse already and that did it not help me.

I read it may be the mode actuator or the control module but no one is specific. Air will come up the defrost and the floor and even the rear but not the front.

I'd Like to do this myself so any help would be greatly Appreciated.

My wife is pregnaunt so I need to get this fixed ASAP Thanks.

It is the mode door actuator. Because it is a such a common issue I would suspect it is the issue. There is a thread going on now about replacing it. I will see if I can find it for you.
