openair Posted January 20, 2016 at 05:32 PM Report Share Posted January 20, 2016 at 05:32 PM Climate controls recirculation turns itself off repeatedly after 5 minutes. I believe this may have been occurring since I recently had my heater replaced. I know it did not occur before that. Anyone else experience similar?

Russael Posted January 20, 2016 at 05:50 PM Report Share Posted January 20, 2016 at 05:50 PM Nope. I always manually control recirculate and it never turns off/on without my intervention. Quote Link to comment Share on other sites More sharing options...

stevedebi Posted January 22, 2016 at 07:02 PM Report Share Posted January 22, 2016 at 07:02 PM Ford hot line says it's normal From the manual "Recirculated air may turn off automatically in all airflow modesexcept MAX A/C to reduce the possibility of fogging."The C-Max has the same wording in our manual. I discovered recently that my DEFROST setting automatically turns off the recirc. If I press the switch while defrost is engaged, it turns off immediately. So it is always fresh air with the defroster on. Quote Link to comment Share on other sites More sharing options...
openair Posted January 24, 2016 at 12:06 AM Author Report Share Posted January 24, 2016 at 12:06 AM (edited) Defrost (by itself) instantly turns off and disables the recirculation button. That section refers to the behaviour I described above where in manual climate controls such as floor vents are selected the recirculation will turn off after 5 minutes. The vehicle has a humidity sensor that turns off the recirculation to prevent fogging. That's what the tech and hotline said and agrees with the manual.However this behaviour only occurs, for me anyway, in manual climate settings such as floor vents. If vent selection and everything but recirculation is left to auto controls the recirculation will remain on indefinitely. So manual it auto turns recirculation off but auto leaves the recirculation to manual control. This is very backwards way to design a system and I've a hard time believing it is really intended to function this way and should not function in more of an auto+auto and manual+manual way.For example last night climate controls were full auto and I had turned on recirculation. Recirculation remained on for probably 15 minutes until the windows began to fog (the reason stated why it has been turning off). I then turned off recirculation and left everything as else as it was. The windows defogged a short time later.I than manually selected floor vents and turned recirculation back on. It auto turned itself off after 5 minutes. Why would it only auto turn off when part of the system is on manual and not when the system is fully auto?If recirculation is going to auto turn itself off it should do so when the climate controls are set to auto as well. To have this function opposite the auto or manual function of the rest of the climate control system is just poor design. Or hopefully, and I may bring this up again with the dealership, something reproducible to point them to my other climate control issues.

expresspotato Posted January 30, 2016 at 05:15 AM Report Share Posted January 30, 2016 at 05:15 AM Yeah I don't like that it turns off either. If I wanted it off I would have turned it off. I'm fine with the fact that it turns off when front defrost is on, but if I explicitly turn on recirculate I expect it to stay on. Quote Link to comment Share on other sites More sharing options...
