I have a 2014 Ram 1500 Sport with dual climate control. For the past few weeks, the a/c seems to have a mind of it's own, even when not in "auto". I can turn the fan speed all the way up and the temperature all the way down and it will blow cold air for a bit, then warmer air, the fan speed will speed up and slow down by itself as well. After reading up on the mighty world wide web, my personal opinion is that the Ambient Temperature Sensor is bad. But then after reading on this forum, everyone that had issues with their sensor had codes thrown and lights coming on. I haven't had that. My question is, has anyone else had similar issues or are there any HVAC professionals that have some input on this issue? Thanks in advance.
