Looked at mine a little more last night.
Took another look at the drivers side actuator.
Cycled heat to AC and that one moved and shifted like it should.
Only heat out the driver's side vent still.
Pulled the console side panel off passenger side, see what appears to be another actuator SANDWICHED between sections of the air box.
Tried cycling heat and AC a couple times, but could not see enough of that actuator to tell if it was moving or doing anything, couple taps with screwdriver then some frowns as I imagined trying to get at that actuator.
Guessing that must be the one that gets the Sawzall treatment in YouTube shortcut videos
Hoping this is not what I really end up needing to get at.
