4x4 Will not release om blazer-97

If it is 4-button Auto 4WD, the two hoses on the vacuum solenoid on firewall (above distributor) may be switched (reversed) - trapping vacuum when solenoid is shut off (only one side is vented). Does the actuator release when hose is unplugged from it? Does the solenoid shut off vacuum passing through it when 2WD is selected? Note that none of this applies to 3-button 4WD (no auto button).
