95 roadmaster wagon. I've tried searching and all I've been able to come up with is the vacumn line on the rear of the manifold. That line and check valve are intact, I can't find any obvious leaks under the dash, and the vacumn motors seem to be free. No vacumn at the motors though. All fan speeds work, and the electric motor that controls temp. On the middle of the hvac housing works as it should according to what I have read on here. Where do I go now? Do I need to find another climate control unit? Or is it in the vacumn log by the glovebox ??
