Just got back from a long highway drive. Did a lot of experimenting with a/c and e/c controls + the recirculation switch.
As reported earlier in this thread, I lose center vent air on acceleration. What I'm also now seeing is that I can reclaim lost center vent air after the reading on the economy gauge more or less bottoms out by switching off the a/c; then swicthing on the e/c. After a few secs., I switch the a/c back on and center vent air continues to pour out until the economy gauge needle goes to the high side.
I have a vacuum pod issue which controls the blend doors.
Thank you all for your interest.
