Why does a 1995 ford bronco air conditioner stops blowing when gas is applied?

If the vents stop blowing when gas is applied, it is likely a vacuum problem. The vent system is controlled by vacuum, so when the engine is under load, there isn't enough vacuum to run the vents. How you test this is when the problem occurs, the fan will still be blowing air, however the flow of air will be out your window defrost vents at the top front of the dash. On a 1995 vehicle, it's likely just some of your vacuum lines are broken, and need replaced or repaired.
