Just had AC fixed. Now when I accelerate, the air blowing out of the front dash vents stop and the foot area gets more flow. Let of gas and the dash gets all fkow back. Was told it is a vacuum leak. I have a long vacuum line i found with a bolt in it. Without bo;t it sucks air. I think I need a vacuum hose diagram. Where could I find this?

The problem is a vacuum leak. If the system works when the engine is at an idle and not under a load, chances are you have a leak under the dash. check for leaks there first, and see if you can locate the supply hose from the engine to make sure it is working. If they are all attached, make sure there are no unrelated vacuum leaks on the engine which could lower the pressure.
