Question about 1994 Oldsmobile Cutlass Ciera
When i excelerate the air stops coming out the vents and starts to come out the defrost vent
It sounds like you have a vacuum problem. When the engine is running it generates a vacuum in the exhaust manifold. That vacuum is used to move the actuators inside your dash to the position you chose with your controls. If you have a vacuum leak or something interrupts the vacuum, the actuator will move to its default position which is the defrost vents. It sounds like the act of accelerating is somehow interrupting the vacuum. I'd look for little cracks in your vacuum lines and check your ERG valve.
