melgriffith Report post Posted October 10, 2013 Hello I haven't used the heater since March. I used the heater today, it was a bit nippy after work, and the heater didn't work. I checked the fuse, tested the AC, everything looks good. Anyone know why the heater isn't working? Mel Share this post Link to post Share on other sites
WWWPerfA_ZN0W Report post Posted October 10, 2013 AC was blowing cold air? When on heater, is air coming out? Was the Edge already a bit warmed up before you used the heater? If the air is not coming out warm, could be a plugged heater core. Share this post Link to post Share on other sites
melgriffith Report post Posted October 10, 2013 Hi Yes, AC does blow cold air. For the heater (turning temp control knob to full heat) air does come out. Ran the heater for 30 mins during the commute home, no heat. Thanks Share this post Link to post Share on other sites

WWWPerfA_ZN0W Report post Posted October 10, 2013 Per my 2007's shop manual, these are the diagnostic steps: Low engine coolant level Engine overheating Plugged or partially plugged heater core Temperature blend door is binding or stuck Temperature blend door actuator Heater hose is kinked or binding (check very carefully when engine is warmed up, may be hot enough to burn) The actual controls (mechanical/electronic) are not mentioned, but there could be a fault in there as well.

redsvt2001 Report post Posted October 10, 2013 Check your engine temp. If it's running cold, the thermostat could be stuck open and only running cold antifreeze through the heater core. Also check the hoses under the hood at the firewall once the engine is worm. Both hoses should be hot. Share this post Link to post Share on other sites

macbwt Report post Posted September 25, 2016 Most common failure is the climate control module. You would need to hook a scan tool to it and start a diagnostic or even try to reprogram it. If programing does not work then a replacement may be the solution. 1 Share this post Link to post Share on other sites
enigma-2 Report post Posted September 25, 2016 Could try running a self test on the climate control module. Procedure was explained in the post: http://www.fordedgeforum.com/topic/15071-climate-control-problem/ 1 Share this post Link to post Share on other sites
