1998 Ford E150 Cold Air only coming out Defrost

We bought this van recently. It had no air. It's a 1998 Ford E150 with a 4.2 V6. The air only blows outta the defrost. We put some Freon on it and it blows cold, but still outta the defroster. Any ideas on what to do now?

Welcome to the forums.

The climate control system uses vacuum to operate the doors. When you turn the knob to different modes do you hear any low whooshing (air) sounds ?

You may have lost vacuum to your system. The vacuum line that feeds the system enters the cabin behind the battery. There should be a place at that point to disconnect it and check for vacuum from the engine. There vans have a vacuum storage tank that's in the front wheel well.
