that's what I already said!Or maybe it's in defrost so the AC would be on.
So it is normal for.the fans to be on when I have the hvac set to defrost the windshield? And that is normal for at least the cx5

Surely it shouldn't matter whether the radiator cooling fan is on or not, since the thermostat is restricting the coolant flow to only the engine and heater until it gets hot enough to let some hot through to the rad and draw some cold back?
Yes, it's normal for the fans to be on, in the engine compartment, when the defrost is selected.
Sounds like bad sensor or stuck valve to heater core, heat should come out vents; doesn't matter if ac is on (it often is, to dry air). Dealer will get you a faster answer than internet brigade...
you're going to be disappointed you wasted your time because you didn't believe usTo the dealer it goes. Thanks for the advice

heat will come out poorly from the vents when A/C is on... A/C cools air, DUH!
furthermore, defrost mode automatically switches to outside air mode just like how it automatically switches A/C on.. this is a "feature" of most modern cars (pretty much anything made within this century)
the owner manual says this, the car is designed to do this and can be observed just by looking at what comes on... if there was truely an issue, the "check engine" light would've came on long ago with a "thermostat stuck open" fault code
