Question about 2003 Ford Expedition
I have a 2003 Ford Expedition. Approximately every 10 minutes when the A/C is on MAX, something sounding like "flaps" in the airduct restrict air from flowing through the front vents. I have to either turn the fan control down to "1" and then back to "4" for the "flaps" to open, or turn the air controller to "Off" and then back to "A/C Max."
1.) What would be causing the problem?
2.) What would be involved in the repair?
3.) What would be your best ball park estimate of the repair cost?
Check the actuator motor on the heater if controls the doors that direct the heat and ac. It is an easy replacement part and as to the cost I wouldn't know but you can check price on line at autozone.

Chances are the electronic/digital HVAC control unit is bad. This same problem happened to me and I had to replace the entire unit. The dealer wanted to charge $800 for just the part! After I freaked out on them, they found a used one for less than half. Sorry, but there's no easy fix here.

Sounds like your temperature actuator is not moving or your temp door is broken. On max a-c ,coolant is shut off to your heater core allowing only cold air in.

I had a 1999 Expedition. When you put the 4x4 on it raises the vehicle an extra inch or 2.
It may help to turn the 4x4 off. Two wheel drive is a lower air setting.
Your original pump may still be good. The problem can be in the front. The compressor is not filling the front suspension to the cutoff point. It will lift the rear after the front end is at running height. Since you lost the front end first, the remaining air bled out there and then the rear came down. Once you shut down the car the suspension was done, all the air was let go.
There are adjustment solenoids on the body but you need someone qualified to repair this.
