Hello all,
Ok I have a 2011 Ford Edge SEL. 3.5L, 2WD and no tow package. My wife drives the car more than I do, but she has told me about it over heating. I have also seen this, and doing research on here gave me some excellent Ideas of what to look at. With the engine being cold and starting it up. I turned the A/C on max and could hear the fans kick on. I also observed a small spike in the RPM's with the extra load. This lasted for 3-5 seconds and I would hear the fans stop and see the RPM's reduce back to where they were originally. I minute later the process repeats its self. The A/C will not push out much cold air when the car is warming up. Take it for a drive and the A/C puts out lots of cold air. Driving on the freeway the A/C works great and the car temp is where it should be. Driving around town with stops or at a drive through the A/C stops putting out cold air and puts out stale air. Also when the car is warmed up and we are driving around town the temp gauge will rise past the normal operating area if we are at a stop or in a drive through line for any amount of time. This will happen regardless if the A/C is on or off. Reading this forum and others I immediately looked to the fans being the culprit. I replaced the fan assembly, but there was no change. I also replaced the thermostat and had a coolant flush done and there is no change in the symptoms. The one thing that I did observe is that the fans would remain on for about 30 seconds after driving it a while and coming to a stop and turning the car off, which I did not recall happening before the fans and thermostat were replaced. The SES/CEL is not on, but I can get my code scanner back from a friend and scan it if need be.
Could this be a sensor of some type failing to turn on the fans when its needed? Maybe the Coolant Temperature Sensor? I thought that may be the A/C was causing the overheating issue, but it will overheat with the A/C turned completely off.
Any thoughts or suggestions are greatly appreciated.
Thanks
Jason
