My wife has a 2011 SLT. The temp does not get cold nor hot (70 degrees at the vents). Upon further inspection the actuator does not move when I try to change the temp. So I replaced it - still does not move. It seems to be stuck in the middle. Did the reset, still nothing. The control unit lights up and appears normal. The fan speed goes up and down fine but not the temperature control for either side or the change to defrost.
