moosedaddy Posted September 22, 2015 Report Share Posted September 22, 2015 I tried running my heater the other day, due to it becoming a bit chilly where I live, and noticed that there was no heat coming out, even after running the car for a while. I have no check engine light, ran a fault code check using my obd2 sensor, but still nothing shows up. I'm a bit concerned since this is my daily driver that I'll be using during the winter months, but I'm not sure how to diagnose my problem. Can anybody provide any input about what my issue may be and how to confirm it? Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted September 22, 2015 Report Share Posted September 22, 2015 Manual or automatic climate control? Was the Edge at normal operating temperature? Mileage? Check the cabin air filter, if it's never been changed, it is probably blocked. Radiator fans working ok? Check coolant level in the reservoir/degas bottle. Is it FULL and in good condition? If you had a ratcheting or clicking sound coming from the dash, the blend door/actuator is suspect. If the temperature of the heater hose going into the cabin from the engine bay is not hot, you may need to flush the cooling system. The heater core may also be blocked by debris caused by faulty design. Just to start you off. Quote Link to comment Share on other sites More sharing options...

I'm not exactly sure exactly what the mileage is. Somewhere in the High 20k, low 30k's. The cabin filter has definitely never been changed. I'll have to check that out. I'll have to check the radiator fans as well. The coolant was one of the first things I checked and all looked well, but I will check again to make sure. Definitely don't hear any sounds. Should I hear this sound regardless if the car is idle or driving? The heater core is my biggest concern. I really hope it's not that. Is the heater hose easy to access? Can I just see it once the hood is opened? Also, is there a way to check the heater core without taking apart the dash? Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted September 23, 2015 Report Share Posted September 23, 2015 The blend door/actuator is probably ok then. The sound will definitely be heard when the system is turned on, sometimes even when it's off. The usual way to check the heater core is to turn on the heat and check the temperature of the hoses at the firewall after the engine reaches operating temperature. If the outlet side is not hot, there's either an air pocket in the heater core or the core is plugged. You can check the hoses by hand, or by using an infrared "gun" thermometer. These hoses are vertically stacked, at least according to the diagram in my 2007 FSM. Quote Link to comment Share on other sites More sharing options...
peterc Posted June 14, 2017 Report Share Posted June 14, 2017 I have 2012 SE model which has single manual heater and had no heat few year ago, but I got it "fixed" easily. you could try this: take out the kneel panel (just 1 or 2 nuts), and you will see the actuator mechanism on the center console side when you really crawl close to the floor. now pull out the electric connector to the actuator. then turn on the heater, now plug the connector back. You may need to do this several times. This "hot" action may jump start the stuck mechanism. In my case, it worked after I tried doing this. Then I apply some locker grease around the joints of the actuator. the heater works since then no problem. Quote Link to comment Share on other sites More sharing options...
