ScarlettB Posted August 4, 2020 Report Share Posted August 4, 2020 2008 Edge SEL ~180K mls with everything HVAC original, owned since 2011 This is my wife's car but I drive it quite a lot. The other day I noticed for the first time while sitting in a drive thru that the temperature gauge had gone all the way to the right by the time we took off. I've never noticed this since we had the car so I didn't think this was normal. When repeating the issue later, I found confirmed that - with AC off - the gauge went all the way to "H" before the driver side fan kicked in. Upon the fan running, the gauge went quickly back to the middle position. Next I set AC to 60 F, and it took a while and some driving for the passenger side fan to start up. Gauge however never again moved from the middle position (it was ~80 F outside) so all that seemed normal to me. My question is, would it be normal for the temp gauge to ever go to "H" before the first fan goes on? Or does this indicate an issue with the control module or anything else? Thanks for reading and any tips.... hopefully this hasn't been asked before. I haven't found anything on "almost, soon to be(?) overheating".

akirby Posted August 4, 2020 Report Share Posted August 4, 2020 Time for new Motorcraft fans - not aftermarket. 1 Quote Link to comment Share on other sites More sharing options...

ScarlettB Posted August 4, 2020 Author Report Share Posted August 4, 2020 Makes sense.. Thanks. Looks like the fan assy is Motorcraft RF-295 and on amazon for $242 right now. Less than I thought and replacement isn't difficult from what I'm gathering. Quote Link to comment Share on other sites More sharing options...
ScarlettB Posted August 25, 2020 Author Report Share Posted August 25, 2020 Worked indeed like a charm. Replaced thermostat also while I was at it. Now everything works as it should. Interestingly, the fan speeds called out on the new module label were slightly higher than the old ones. 1 Quote Link to comment Share on other sites More sharing options...
