2014 Ram 3500 Tradesman Driver Side AC Vent Not Blowing as Cold as Passenger Side

[Vince Sandoval]

Has anyone had or heard of any 4th Gen Ram Truck driver side vent not blowing as cold as the passenger side vents? Notice a two days ago that the driver side was blowing warmer than usual and when I checked the passenger side vents I could feel a temp. difference that it was colder than the driver side vents. Haven't used a thermometer to measure the temp. difference, but it's definitely noticeable when you side on the passenger side that its colder. It is a Tradesman edition with 4 speed fan control.

Check with a thermometer and park somewhere in the shade. An overwhelming majority of people have a bad perception of judging temperature accurately. Any form of solar radiation will askew it even further.
It's possible there may be problem with a blend door but seems strange it would happen on one side and not the other. A partially plugged coil could be another issue.
