No vaccum at the heater select switch?

No vaccum at the heater select switch?
I've got vacuum at the check valve, but not at the selector switch.
I unwound the wire loom that the black vac line is in. It's fine as far as it goes into the heater box. So I'm thinking its leaking inside the cab. Can not hear any leaks under the dash.
Any idea's on where the problem could be?
