You have a vacuum leak from your diverter controls. When that hapened to me, I found the leak right next to the firewall in the engine bay.

Those vacuum lines are hard to track down.

Check all vacuum tubes and hoses under the hood before tearing down the controls.
My first van had that trouble for a while,it was simply a little white tube under the windscreen that had been pulled out of where it was supposed to go.
