My rear air conditioner is blowing air but it is not a full cool and the air conditioner pipes in the rear under the car one pipe is and one cold I would like to know if I need to replace the expand valve or the blend door actuator? I know where the expand vave is located, but I do not know where the blend door actuator is located
for my rear air conditioner. Thanks

That still needs to be determined. You will have to remove the trim cover to expose the evaporator housing and you will be able to see the blend door actuator and visually see the center turn when the temperature is changed if it is working.
