Not to sure about your particular Dodge.
Blender door- usually operated by vacuum on older trucks and electric on more modern heating systems with fancy heat control, easy to check. Have Girl Friend operate the temp control and look and or listen for the actuator to turn the lever, I have actually pulled apart a heater box to find debris blocking the fresh air door from closing all the way. (that was on older trucks, you got to love those little animals)
AC-Usually there is two settings on the AC, one circulating and one not, or a MAX A/C or A/C the one that recirculates the air can cause your system to fog up the windows. The fresh air option is the one you want to use. if the blender door is broken then it can cause the fog
Heat= -50 to -55 degree max for your antifreeze level, if you drop it colder then that it can actually stop the flow through your heater core on the really cold days, I usually run mine around -50.
With your truck at operating temp check the heater lines to see if they are warm, if they are not then you might have a blockage with the valve, but since you get really hot air with the AC probably not the issue.
I run a cover on my Diesel, it helps with the motor heating up but I never noticed it effecting the heater one way or the other, I just rode in a friends truck and just from idling too long his truck actually got cold, I have just a little but newer truck and mine doesn't do that.
Don't know if that is at all helpful, did this just start happening or has it been a regular occurrence? what temp do you start to notice the lack of heat? Do you know others in a similar year truck to ask them if they experience the same problems? It may be just a bad design all together.
