Driver's side AC intermittently blows hot air

[booster]

The AC on my 2005 Suburban will intermittently blow hot air. Cycling the ignition may or may not temporarily fix it. Usually at the next ignition cycle it will blow hot again. It has the electronic AC controls.

If the passenger side blows cold and works as it should, then you've got a bad actuator

what if its the opposite? mine tends to blow searing how engine air no matter what temperature i set it to on the passenger side. i think theres a flap back there that doesnt flip over or something?

There are 3 actuators controlling damper doors.

 

Y'all might try the HVAC recalibration in this thread:

Recal didn't fix it. Does anyone have the part number for the drivers side actuator?
