air flow does not come out of air vents,air flow comes out the front vents by w

Is that the only place the air will come out of or can you switch to anything else such as the floor etc.?

The air distribution in your Cadillac is controlled by electric motors, one of them might have failed. The best thing to do in this case would be to take the vehicle to a repair shop that can perform a diagnosis on your car and figure if that is the case. We can certainly do it.
