I have an 06 dodge Dakota SLT crew cab with a 4.7. I’m trying to figure out which blend door actuator controls the heat to cold. I all of them click when I change my temperature from hot to cold and from blowing AC to defrost. I can hear through the sink when is make a noise when I do these changes. I’d like to change the one that controls from hot to cold first. Can somebody give me the location on this one. I know there are two that I can reach from underneath the dash on the driver side and I’m not sure what these to do. Any answers would be appreciated before I start changing parked out.
