You have a vacuum problem- somewhere. It sounds like you have a total loss of vacuum to your ac fromunder the hood. There is 1 small hose through the firewall to the pass side of center that goes to a vacuum source,check it first and then trace to under dash if the problem is still there. This is not guarnteed, but is 95% of vent switching problems.
