We bought a 2008 edge new, it is wifes daily driver and she loves it. Only real problem we had was the tranny stated shifting very ruff. Dealer flashed it and we have not had any more issues. The AC sucks in this car I have always assumed it was just under sized. On a 100 deg. day you can barely feel the cool air coming out of the vents, it does blow better out of passenger side vent then drivers side vent. Anyone else have this issue?
If your driving on highway its takes about 20 min to cool off car, if your driving in town on a 100 deg. day it dont cool down. The dealer said they didnt see any issues with it.

 

Are you saying the air flow is not adequate or the temp of the air is too warm. Air flow can be blocked by mouse nest or leaves inside the duct work or blower motor. I assume the blower changes speeds and you have all of them ? If you have plenty of air, but its not cool, i would look at the compressor gas charge. (PSI GAUGE) Might be as simple as half pound of 134 gas has leaked out over the past 5 years.

 

My wife has a 2008 Edge SEL and the A.C. in that thing blows quite cold. I would have to agree with Steve on it possibly being low on refrigerate.

 

The air is cold it doesn't have much force when it comes out of the vents. It has more force on the floor or defrost(but not a lot) then on vent. Every other car I have owned you could feel AC on your face while you were driving. In this one if you put your hand 1ft from vent you can no longer feel the air movement. The blower works on all speeds. The little vents on the console for the rear seats keep the back seats cooler then the front.

 

I would look for a A/C specialist shop in your area; they'll be cheaper than the dealer and will pinpoint and fix the problems.
I worked the Ford line in the early 90's and am noticing there are too many parts changers out there. They may have went to school, but you have to learn how to troubleshoot problems--this is becoming a lost art.
Sounds like the control head or the motors that direct air throughout the plenum inside the dash are not working properly and maybe diverting the cold air to the wrong places.

 

You may have a blend door or vent blockage issue. I once fixed a customer's problem by taking the vent hose off and removing the roll of Tums from the bend door. Not an edge but a later model car. we have an 09 Edge, and the vents will blow your hat off. Good luck.

 

On my wifes edge when we first got it (new to us. It was used) there was virtually no airflow. Checked the cabin air filter and it was clogged. It is behind the glovebox.

 

it is indeed a cabin air filter problem. if your edge only has a screen, you can wash it out or simply throw away the screen and put a cabin air filter in its place.

 

I know this is an older post, but I wanted to share my experience with this same issue. 07 Edge had very little ai8r coming from the vents, the temps were okay. It was a cabin filter that needed cleaning. Clean or replace it, the air's like a tornado now (slight exageration 0
