I had the same problem and after three weeks called a dealer and was told to look under the battery box where a vacuum line runs to the round vacuum can under the right front fenderwell. Sure enough, the line was frayed and broken. The line repair cured all of my system duct direction poblems. You could also have a problem where the line plugs into the vacuum canister. You can see it from underneath the front bumper assembly.
