OK, I did the reset procedure in one of the videos, and that worked for a couple of days, then I had to do it again. I don't have a problem resetting it often, but is there something to look at when I have to reset it every day or two to get heat? FWIW, over the summer I had the blower motor fail, and I replaced it with an aftermarket one. It seems that I started having issues of one sort or another shortly after that. This was all shortly after it was in the dealer for a month or so for a running problem. Could that have had something to do with it? I have looked and it doesn't seem that there is anything in the way of the blend motors.

My 2011 Edge, with Sync and the touch screen, is having heat issues. There seems to be no rhyme or reason to it, sometimes it will blow hot, sometimes it will blow cold. Sometimes when it is blowing cold I can switch which vents it is using and it will start blowing hot, then after several minutes it will go cold again without making any changes to the controls. I also noticed when switching the vents around when I had it on foot and defrost the foot was blowing cold and the defrost was warm, same when I had it on foot and dash, the dash was warm and the foot was cold. I have been trying to see a pattern in the last few days, but I have not been able to establish one. Seems to just be random when it will do whatever it wants to. Any ideas what I should look for? I'd rather not spend another grand at the dealer. Thanks.

Thanks for the references. My fan controller only has 1 out that splits to both fans. When I looked at it I didn't have any power going in to the controller. So in frustration I gave the top of the fuse block a thump and the fans both came on. Now it is intermittent, sometimes they run as they should and sometimes they don't. And further messing with the fuse block don't seem at have any effect. Any ideas? Also, looking at the wiring diagram, I don't see any input from the PCM to the fan controller on the vehicle. I have a 2 wire input and a 2 wire output to the fans, and that is all that I see.

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?

It has about 145K on it. That seems pretty early for a timing chain, but then again I have seen some weird stuff on this car. I am pretty mechanical, and worked as a mechanic for several years back in the 80s. But these cars are totally different animals compared to back then.

My 2011 Edge Limited AWD started to idle rough the other day, and the check engine light came on throwing codes P0018 Bank 2 Sensor A and P0021 Bank 2. I normally attempt to do my own maintenance, at least when I can. What are the possible causes of this? Is there anything that I can do to troubleshoot without throwing parts at it? It also seems to have lost some power, but I didn't really try to run it hard after the symptoms started. In fact since then I haven't had it over about 35mph. And haven't driven it since the day it happened. I would rather not have to go to the dealer, but obviously will if I have to. I doubt that it makes a difference but about a month ago I replaced the oil pressure switch. Thanks :)
