My 99 blows out of the vents while at idle or stopped but when under load it starts to blow out of defrost vents. I know its a vacuum leak but don't know if behind dash or somwhere under hood. only thing that has changed is transmission was rebuilt a week ago,before that it was fine. Any suggestions
