Well after researching and a few phone calls I found the info I needed. I will post it here so in-case someone else is looking for it. 1. the A/C Expansion Valve located on the fire wall behind where the hoses run.Remove air intake system that you had to remove to get access , Once there you need to unbolt one of hose brackets and also the A/C line bracket that is mounted on the right side fender well. This unit is in set into the firewall, 10 mm socket and a allen wrench are needed to remove. This is not easy to get out as you have wiggle it quite a bit to get loose. It is a tight fit with the a/c lines to put on the new O rings. Lube with a/c compressor oil. Before you re assemble the air intake system that you had to remove , now is a good time to pull a vacuum on the A/C system, this will save you time if you have leak as you have access to this area. 2. The A/C Accumulator Filter is located on the Condenser it self , raise the car and remove the air deflector , look up on the left front side where the radiator and condenser are , you will see a hole in the core support , then you can see a nylon white plug which is the A/C Receiver Drier and plug , big hex wrench is needed, use the new plug to size . more details on - https://www.carid.com/2011-ford-edge-air-conditioning-heating-parts/?filter=1&sub-model[Liter][]=3.5Lyou need to remove to remove the filter bag , get a small hook tool and pull the bag out, be-careful not to taste test the a/c oil that will drip out. 3. When you go to recharge the a/c system you may not get the a/c compressor to kick on to take the proper charge , what we did was to pull the A/C clutch relay #68 and put 12 volts to it. Be sure to look up the relay number to find to 12v output pin. <-- this is important not to fry other parts like the PCM Next we had a tough time in getting the system to take the proper amount of charge of 1.5 lbs . So start by evacuating the system , then add .3 to .5 lbs at a time till the fans kick on , then replace the relay and go about charging the a/c system like normal. When we found out was it did not like a full charge all at once but by adding a little bit at a time we were able to get the system up and running . Now keep in mind you may have to go back and add a bit more charge after 24 hrs since the new Freon take longer for the gas to completely expand.

Another question , where is the A/C Expansion Valve located ? could this lead to a ususal high pressure reading on the gauges and not allow proper freon refilling ?

Okay after a long night we replaced the a/c unit (flushed etc etc ), pulled a vacuum and it held, added Freon, it only took a little bit, the compressor clutch still will not engage, low pressure sensor was replaced . so I am back where I started . I am still thinking i have a wiring issue. With the scan tool the mechanic did force the clutch to engage and fans did activate . we did try to fool the A/C pressure sensor by jumping it , but it did nothing. Any ideas ?

They are not turning even when on the max setting , I just replaced the low side pressure switch with the same results. Had the mechanic hook it up to a his computer, they could then manually over ride it and tell the a/c unit clutch to turn on, which it did along with the fans. Which is confusing to me. On Edit we did trick the fans to turning on and they ran fine. akirby Thanks for the videos , but what I am chasing down is possibly a pinched wire in the harness when they reinstalled a new engine even though they dropped the motor from underneath .

Thanks for the welcome. I posted in this old thread, maybe someone can help me out with this .

I know this is old post but the link to the Edge Cooling Fan wiring pdf is broken, would someone happen to have a working link ? thx BWT I have 2011 limited 3.5 that went south , had a used one installed and i am thinking the mechanic did something to pinch (?) the wiring harness , since now the pcm will not send a signal to the a/c clutch or fan motors . I need to back track the wiring from where it plugs into the firewire wall.

Here to hunt some info and help , Yes my user name is a truck I own as well as a Edge but also the same name I use on FTE .
