Re: Air condition issue
I'm not familiar with the Ranger directly but most Ford products use vacuum to control their hvac systems, and I still think you have a problem in that area. There's a chance that there is a leak in the control unit (knobs, etc) itself or the hard plastic lines that go to and from the controls.
The system works on pressure, not volume, so it wouldn't take a large leak to cause a problem and it wouldn't have any effect under the hood as far as the engine's operation.
