Low heat output on driver side

[Mrmegoo]

I have developed a problem this year with very little heat on the driver side. If I run the heater on the floor setting, the passenger side gets really hot but not the drivers side. Also the same on the bilevel or dash vents. My truck is not equipped with individual comfort settings, so something is not letting the air flow through the heater core to driver side. Any help would be appreciated.

My 2013 does the same thing.I flushed the heater core and the coolibg system.Replaced thermostat.But I hear it is most likely the blend door screwed up.As long as I dont freeze to death I aint gonna do anything else about it.

Our 2004 2500 did this. Had to eventually replace the blend door.
