I have a 2012 Ram 1500 4x4 with 5.7 hemi. During the winter the heat would blow hot, then switch to cold, then back to hot. All while the fan also blowing only on high. The fan would blow a little on the 3 lower settings but not much. Now in the summer the ac will blow cold on highest fan seeing, and periodically blow a little on the 3 lower fan settings. If I put it on Max air (recirculate) it will cycle from hit to cold inconsistently. I have already replaced the resistor, and the heater controls. Not sure what the next step is. Thanks for any help.
