99 Buick Regal HVAC blowing through all vents

  • 1999 BUICK

99 Buick Regal LS It has the electronic controls for the HVAC system. The system gets cold and hot but it doesn't matter what vent you choose even on automatic it blows out all vents but mainly the floor vent. I have heard that the contol panel goes out on these models but wasn't sure if that is it or could there be a vaccum line detached?

Do you
have the same problem?
