If neither switch works it is a bad connection at the motor or bad ground or a bad motor. Remove the door panel unplug the motor push the switch and see if there is 12volts on the wires if there is the motor is bad There are small brushes in the motor that go bad tap on the motor while pushing the switch if it works that way replace it

Actuator motors either get a tear in the rubber or a hose is broken and not letting vacuum assist in its opening.
You can try moving the lever by hand and see if the air gets colder on the bad side.

you cannot repair the actuator you need to replace it with new one. These motors turn but get weak with time. if you test it, it works, put it in and it doesn't. this is because the motor is weak, unfortunately GM does not sell these motors separately.

First....buy a drivers side air flow actuator at a auto parts place for dual zone heating/cooling.
(NAPA etc will have it.....or the dealer)
Open the glove compartment.....all the way....you may have to take the screws out at the bottom......look in at the heater assembly....look over to the left....you will see the two air flow actuators.
Look at the part you have and match it to the part on the heater assembly.
The actuator that is closest to the engine is the drivers side control.
Try your controls and check for heat and cooling on both sides.
The stepper motor in these actuators goes bad on quite a few...but over look that.....you have a great car,good for many miles of trouble free driving.
