First winter with my 2014 Fusion Hybrid. Noticed that my heater blower will not start blowing until car gets up to a certain temperature. I don't know what that temperature is. Problem is that ICE sometimes shuts off before the heater blower starts running. This is bad if trying to defrost car in winter. Car will not defrost or heat up. Only solution I found is to force ICE to run by driving it and this sometimes takes 5 or 6 miles before the heater blower fan will start working. I can often feel warm air at the vents but I cannot get the the blower to run. I tried auto, max defrost and all the manual controls I know to try and force the blower to run when it is cold but haven't been able to to get it to blow until car is fully warmed up. Doesn't seem to be a problem with temperature is above freezing or when the blower fan starts to run. Any ideas on how to fix this? Thanks for your help.

Ever since it got cold enough here (northern OK) to warrant using the heater in my 2013 MKZ Hybrid, I've noticed that the heater blower is really loud--loud enough to make me wonder if there are some "doors" or vents inside the heater system in the dash that are not opening properly. Once the car's interior warms up enough such that the heater needn't run on high, it quiets down quite a bit, but it really makes quite a racket when it first tries to heat the interior of my car. I expect some noise, of course, but this is loud enough that it makes me wonder if there's something amiss. Are others experiencing this? I'm hoping to hear from you, whether you are or are not experiencing the same thing. Thanks in advance.

This may be a silly question, but I couldn't find a definitive answer in the manual or related documentation. I keep the Climate Control on the "auto" setting, meaning it should stay at my selected temperature (let's say 70) inside the car. I've only had my Fusion HyTi since June, so it's only been used during warmer months. I've kept the settings on "auto" with the "A/C" button also selected. So primarily, the air conditioning has been running to keep the car cooler inside than the warmer temps outside the vehicle. Now, we are entering Fall/Winter, where the temps outside have been in the 50s. So my question is this: Do I need to keep that "A/C" button selected when the Climate Control is set to "Auto" during the winter? Will the "auto" portion of the configuration keep the car warm inside (my selected temp of 70) when it is in the 40s or 50s outside, even if the "A/C" button is not selected/lit? Or is there some reason to keep the "A/C" on to maintain a stable internal temp? Does it "hurt" to leave it on -- meaning, will the A/C run and take up more energy? Or, if the button is left on will the A/C simply not be triggered to run anyway if the outside temp is in the 50s and my selected inside climate control temp is 70?
