You have a vacuum leak for the AC controls. Follow the vacuum line from the engine to the passenger side of the firewall. There should be a vacuum canister mounted on the firewall that the vacuum line connects to along with a check valve where the vacuum line goes into the firewall and into the dash area to the AC controls. See this You Tube video below.
