I took it to a shop and they said it would require ripping out the entire dash to find the problem...any suggestions?
If you can hear the vacuum motors inside the dash moving the vanes to change airflow and the only problem is that it never comes out the dash vents you may have collapsed nipples in the connector at the programmer. Run motor to build vacuum then turn off and with fan speed on low, select different settings, floor, floor/dash, dash, floor/defog, and defroster. This assumes you have the automatic air conditioner with the programmer behind the glovebox and down.
I did the step where I removed the 7 tube connector and slipped 1/8 inch gas line pieces to connect interior tube with the tube outside the connector. The 1.5 inch pieces of tubing worked great. No rattles.
If when you push different buttons there seems to be no change in the positions of vanes in the box, then we're chasing a vacuum source problem.
