Check for a vacuum leak or broken vacuum line first and if all is correct then you will need to check the a/c - heater controller..........
I have a 2003 astro with the same problem, it was the blower motor
Yes.
go back up the stairs or back through the little hole
The vents are controlled by vaccuum from the intake manifold. Check for a split rubber vac. hose on the manifold- Hope that helps.
I am wondering how the compressor on my 1993 Chev Astro comes apart, I have someone who will repair this for me but he is unsure as to what is involved by taking it apart.

In Mordred's underground laboratory, the left wall is made of dirt and can be pushed through (with a little effort).
well it depends on which parts! you need to be a little bit more specific here..
I have the same problem with my 98 astro. I am no mechanic, but through my online research I found the wiper delay circuit boards seem to have issues. One site said the part was $50 from Gm and installs very easily with 3 torx bolts. Hope this helps!
This sounds like a vacuum line problem. First thing I would check would be the vacuum lines and check valves contained in line with them, as well as the vacuum canister. Could also be a problem under the dash with the vacuum actuators in the HVAC unit. Another slight possibility also could be that the controller isn't functioning properly. Hope this helps. Good Luck!
It is located behind the coolant and windshield washer reservoirs. The two wires on the blower motor will lead you to it.
