Maybe it is a vacuum pod issue? I know when I turn on the AC control, a pod inside the dash 'pops', then I start getting cold air out of the vents.

My manual AC does the same thing . Definitely a pod issue or vacuum problem. the one by the blower controls the cabin / outside air door mine sometimes needs a push. I also put the lower handle "defrost / floor" to floor.
If the max ac knob is "in" (blue knob )
floor vents shut off increasing air to upper vents.
If max ac knob is pulled "out"
then Bi level is on and ac will come out both top vents and floor vents .
Theres a pod on the passenger side by the center console. This controls the turning off of the floor vents in max AC mode. If its not working the max knob can be in or out and air will constantly come out of the floor vents. I found that by accident with a mighty - vac. The line comes frome behind the AC max switch.
I also suffer San Antonio summers so the 80% cabin 20% outside set up had to go. The door is in the channel leading to the cabin on the firewall below the windshield. I removed the cowl vent (black screen in front of windshield ) and with my best ability sealed the 1/4 inch gap around the fresh air door. it sits about arms length in the channel. I used silicone . Sure its inoperable but if I need fresh air I roll down the window.
The blower on these systems with all the vents opened is far from what I would consider adequate . More like a light breeze and if your evaporator is dirty its even worse.
My next project : Find a bigger blower and adapt !!
110 degrees and you learn fast!
Hope this helped.
