there is no vaccum to your control panel, check from engine area a small little some are gray lines under hood to fire wall check for woren spots or broken lines to fire wall then inside under glove box check if all hoses are good and hooked up not getting vacum to unit or bad control unit take out of dash and take vacum lines of with car running should have vacum in one line, good luck!
Also check under the driver side dash, there is a round valve with a lever for the vents. Check to see if the lever is connected.
