Had exact same problem with my 2006 Chevy Silverado 1500. Would blow hot air thru drivers vents only and sometimes if I turned truck off and restarted would blow air conditioner for a bit. Rec'd recall letter from Chevrolet in January for this problem.

SOURCE: 2004 Chevy Silverado AC is blowing warm air on passenger side.

You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator

SOURCE: Heat wont blow through heater or defroster vents

The door in the heater box is most likely stuck. It is located under the dash on the passenger side

SOURCE: 2004 chevrolet suburban AC blows hot/cold at same time

You need to replace the drivers side temp actuator that is located on the left side of the HVAC box. It is retained by 3 screws and is fairly easy to replace.

SOURCE: one side air blows cold one side blows hot

GM has a known problem with the electric actuators that operate the blend and temperature doors in the HVAC system. There are 4 or 5 of these in the typical system. Any can start sticking or binding and cause this problem. Sometimes they can be cleaned, or they might need to be replaced. Sometimes resetting the HVAC system controller by disconnecting the battery for 10 minutes, then reconnecting it, will correct the problem.
