Check out https://www.youtube.com/watch?v=Ry5vyIMc6T0 - should be the same as your truck. You can buy them online from just about any parts supplier (it's called the mode actuator).

If you've replaced the actuators and they are working.
One of the blend doors may be broken inside the heater box. To repair or replace the broken door you
have to remove the heater box. This is not a small job. The book gives 6-7 hours for the job. There is a
cheat that I've heard good things about. I guess it can
be done in a fraction of the time. You can find out
about it at heatertreater.net I have not used it myself
but I know somone who has. And it worked well for
him. Hope this helps.

Had same problem on my 04 Suburban. Dealer's service dept said the passenger side temp sensor was defective causing the driver side actuator to continuously search. They replace the sensor about 2 months ago and A/C has been working fine ever since. Repair bill was $400+.

SOURCE: The driver side only blows
Yes it is most likely a vacuum actuator there are more then one . They open and close little doors in the ducts to deriect air flow inside the ducts . They are not easy to get at in most cases however you should look at all vacuum lines going to and near the unit its controlled by engine vacuum . exhust all other opptions first before takeing the dash out . The problem could also be electrical check the control switches make sure the switch is not bad on one side . Spend some time looking and thinking before you start riping things apart. Good luck with it
