Hi,
Just replaced my '99 Expedition Eddie Bauer with 285,000 miles and a lot of kid wear and tear with a '99 Bauer with 60,000 that is about as close to new condition as you will find in 2015.
This "new" one has a slightly different mix of options including a moonroof and lacks the rear, aux. HVAC unit. It does have the small unit on the back of the center console that acts like a booster to blow HVAC from the main, front unit into the 2nd row.
I really liked having the rear aux. unit. Anyone attempted to install that on a vehicle that was lacking it? Generally I know there will be lines for coolant and refrigerant to install with a valve on the A/C to tie it in and a change of fittings to attach the coolant lines. Also the wiring to deal with and controls to add.
What about duct work up in the head liner? Is the head liner with the aux unit any different or does the aux unit just direct air up in the gap between the headliner and roof and then holes are cut to install the diffusers? My old Exp. doesn't have the moonroof so the headliner is different to start with so I can't tell 100% although it appears to have some channels molded into it to for the airflow. Also on fordparts.com they don't seem to list different headliners for rear HVAC vs. no rear HVAC. I've considered just adding it but only having using floor vent to avoid tangling with the ceiling.
How about the compressor, condenser and other A/C components under the hood. Is any of this larger in capacity from the factory when the aux. unit is installed?
As I've dug into this I've just gotten interested as an engineering exercise as much as taking on the project - so any info would be great.
