Cadillac: 1994 cadillac deville no air from front vent, vacuum line, vacuum control

Question
My 1994 cadillac deville does not blow any air out of the front vents. only out of the defrost or the floor.What could be the cause?

Answer
What mechanical work has been performed on the vehicle recently ?. As most problems that occur after a recent repair was made can be traced back to the area of where the repair was made.


There are several possibilities including a vacuum line that has come off it's attachment point, A fault in the vacuum control valve or a fault in the A/C-Heater main controller.

There is NO one thing that is more prevalent than the other. This is going to take some professional testing to locate the exact source.
