Actuator door may have come out of place, my Z71 did the same thing and I had take the dash out to ge to the door to put a keeper on it. It doesn't come from the factory with a keeper, just a gasket to keep the door in place.

did that fix it? this no heat thing is driving me nutz. and if it did not come from the factory with this Keeper* on it where or how do I get one.?

Did you check the flapper door yet? you need to get into it so you can eliminate possibility's

I am not sure where this flaper door is to even start looking.
