I have a 2011 Edge with the 3.5L V6 and neither cooling fan is running, either with the AC in MAX or when the car gets up to normal temp. This is obviously causing it to try to overheat when the car is not moving, and the AC doesn't blow very cold unless the car is in motion. I know the fans fail, and the controller sometimes fails. Question is in troubleshooting. I will have to take part of the air box off to get to the connector for the fan controller, but when I have it off I assume that I should have 12V going to the controller? And then have 12V coming out of the controller would tell me that it is good and it's just the fans that have failed? If I don't have 12V, assuming that I should, going to the controller, what should I look for upstream of it? I have no issue replacing the parts, but I don't really want to spend money for the fun of it Thanks in advance, and if I'm incorrect about that could you let me know what I should be looking for?

 

Fan control module fails when its caused to fail usually due to fan failure so best bet is to replace fans and control module at same time. Mine did sane thing

 

After looking at it I wasn't getting any power to the fan controller. Then I gave the fuse block a good thump on top and the fans started running. But is it still intermittent, and messing with the fuse block doesn't always get it running. But sometimes they will run normally and when they are supposed to and sometimes they don't. This car is driving me nuts.
