Before I go ripping my heat/AC box open thought I better ask. Sorry, no pics, on my phone n it won't let me upload. I now have everything working, I believe, so that I can have heat. I have good airflow to the interior everywhere and the doors appear to be working in the appropriate selector location. With one exception, the heat/defrost actuator lever, left side by driver's knee, appearsto be stuck. The diaphragm is working correctly but the curved rod, in the case, will not move. I can unbolt the actuator from the case and see it travel, roughly 3/4", when the selector is moved. I've tried rotating the lever with some pliers but I can barely move it up and down from center. I'm assuming in defrost mode, no vacuum, it should be up and in all other modes, vacuum applied, it should be down. Tips/suggestions would be greatly appreciated. Thanks!

Hose it down with PB Blaster and keep working it until it loosens up...

Inside should be a straight rod with a flap attached pivoting on 2 bushings. Look along the bottom front edge of the heater box and you should see 2 or 3 flat clips. Pop those off and a section of heater box can be removed to access the heater core. Just to the right of the heater core you will see the defroster flap. The bushings are the target...

If you're talking about the hex heads in the pic, take 'em out. Shouldn't be anything falling out of there unless you have a rodent problem...
