Hello,
I would start by checking or making sure there is a check valve in the vacuum line leading to the vacuum canister for the hvac system. The hvac system is vacuum actuated and if the check valve is bad it will push pressurized air into the system and move the actuators. If that is not it let us know and ther are some other items to check. Good Luck, Bernie
