2014 300 heat problem
 

my heat only comes out one side. both on the floor and defrost, wondering
if it is the blend door actuator ? if so where can I find it ?

the coolant full no air bubbles?

The coolant level is normal.

do you have duel ac controls one for pass one for driver side?

Yes I do, has the touch screen.

both pass and driver motor is on the left side of teh dash where your feet go. remove the small panel then you can see them Have some one move each side and you can seee just which motor is what when the mode or temp is changed.
