LR3 Heater Distribution Issue
It seems that a lot of folks have had the issue where no or little heat is observed blowing from the drivers side vent, but is good on the passenger's side.
The supposed fixes range from replacing the Heater Core to Replacing the air blender door actuators.
So, I figured I would take a poll and see who had which issue.

Had mine done and it seemed to be fixed but one day later it was the same? Should I flush it again? Tech said that not much sediment came out. Does it need to be done with a machine or is shop air pushing water good enough?

Machines are usually good for "coolant exchange". I've never seen one that actually knocked stuff loose and "cleaned" a cooling system. Really dirty systems usually require chemicals that you wouldn't want to put in a coolant machine.
When they did the flush, did they flush the core in both directions? I use water and air and I keep alternating directions. Backflushing gets the most debris, but I sometimes get some forward flushing as well, not to mention the change in flow direction helps dislodge debris.
Repeat cases may require rinsing out the block and possibly replacing the radiator. If the heater core keeps plugging up, then sediment has collected elsewhere in the system and is being re-distributed back to the core.
