Default A/c mode problem 88 c68 electronic climate

I have a problem where air blows out all exits defrost, heat and vents. you have no control except heat will shut the vents off. I checked the progeammer and it's clicking with all the mode changes and it has a good vacuum source. temp control is ok and control head lights up ok. Any ideas?

......to the drivers side of the distributor, there is a small valve with 3 vac lines on it. 1 line goes to the tbi as a feed. i had the same problem 3-4 weeks ago. i found an old piece of vac line and i was good to go.....





***sorry about the large size as i can't remember how to make them smaller
