I have read nearly 2 hours worth of posts on "no heat" and cannot find something resembling this problem.

Here is the symptoms:

1. good vacuum on the heater valve and on the vacuum line going from the valve. Hook it up and turn on the heat, the valve will not open.
2. Climate control head and aux water pump are new.

I currently have the Idle control valve unplugged to keep the car from stalling but don't think that is related at all.

All the fuses are good and I hear the flaps opening and closing when I change settings on the Climate control unit.

Why the hell don't I have any heat???????? It was 24 here in Charleston this morning and to draw a comparison, that would be like it being 50 below in Michigan. We just ain't used to this at all.

The only other thing I can think of is the vacuum distribution module.
Any thoughts would be appreciated.
