This may be due to a fault with an actuator on the heater box itself.I have seen temp actuators fail in allot of similar cases before needing replaced to correct an issue like this here.If this was not tested/checked to see if a temp actuator is the cause here this needs done.If a fault is found with a temp actuator it will need replaced and in some cases calibrated again after it is replaced.If you need info on where the temp actuators are let me know and I can send the service requested.

Do you hear any clicking or ticking noises in the dash area at all when trying to adjust the temperature?
O.k.,after looking through my info on this model here I don't see a procedure on how to test this actuator myself.I will have to open your question up for others here to see if anyone else can assist further on this as someone else may have more info on what to test or do for this here.
new Expert here, is this a climate control system? or manual system?
if you change temp settings rapidly from hot to cold do you get a clicking noise under the dash?
sounds like you may have an issue with the air mix door on the passengers side.
Remove the glove box and foot duct and you can see the air mix actuator mounted to the unit. If you remove the actuator you can operate the temperature and see if its moving. If not then it needs replaced.
the only other option really here if the air mix door for the side was working normally and you had different temperatures, would be a fault with the air control for the passengers side.
