The problem is most likely a bad dual climate control valve. This component is located on the right side near the radiator under the hood. It will have several coolant hoses hooked to it and 2 silver cylinders protruding from it. You can clamp off the heater hoses at the heater core and see if both sides cool then and this will tell you that the valve is letting coolant thru when it shouldn't be.
This will narrow it down to either the valve or the control head inside the car,or wiring in between them. The only way to narrow it down further is if you have a scan tool that could access the climate control data. Have seen several of these valves cause this concern and have only seen one control head cause it.

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

Probably the left temp actuator. The wires in the right I/P junction block could have poor tension also, but it's usually the temp actuator.
