Air Temperature Actuator
The air temperature actuator is a 3 wire bi-directional electric motor. Ignition 3-voltage, ground and control circuits enable the actuator to operate. The control circuit uses a 0-12 volt linear-ramped signal to command the actuator movement. The 0 and 12-volt control values represent the opposite limits of the actuator range of motion. The values in between 0 and 12 volts correspond to the positions between the limits.
When the HVAC control module sets a commanded, or targeted, value, the control signal sets to a value between 0-12 volts. Actuator shaft rotation is the results of a commanded position input by the vehicle operator. With a new actuator commanded value action, the maintained actuator control value is changed.

On this year,it is most likely low on freon,but it could be a actuator motor gone bad.The actuator motor directs temp to that side,but I am thinking,it is just low on freon,if this was helpful,please rate,and thank you.

It can be low on freon,or,the actuator motor foor that side blend door is bad,if so,the dash has to be removed to replace the actuator motor.

Your passenger side blend air door actuator has most likely failed. I hope this helps.
Thank You,
Roy

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 can remove radio to get to them.disable air bags when working around dash.
