Expedition rear ac

I have a 2003 expedition, the front ac cools but the rear ac doesn’t. I checked the rear ac lines and they are cold but no cold air from the vents. I already replaced the ac heater blend door actuator but still no cold air

But there is air flow blowing from the roof vents ? I wonder if the blend door shaft is stripped out where the actuator attaches? When you replaced the actuator did you remove the rear quarter panel? Or did you just do it through the opening it the top? You might pull the actuator back out and test it's function with it plugged in and see if it's shaft does in fact rotate when you move the temperature selector in the overhead console.

Did you replace one or both rear actuators?

I replaced both actuators and they seem to be working good. Their is air flow from the roof vents, I manually tested both actuator door panels and they work.the heater works so I know the actuator that controls temperature is working

yes their is air flow from the roof vents. And I had already done what you suggested, I checked to make sure the actuators where not faulty by changing the temperature on the top **** and they work. I also manually tested the doors that the actuators move and they work
