The heat inside the cabin of my truck comes out just barely warm from the driver's side vent and cold out of the passenger side vents. What could be causing this problem? I've already had my heater core blown out and a coolant system flush and neither has worked. Help, please

Let's say for the sake of arguement, the core is ok, which just because it was blown out, may have worked, then it's possible that the temperature blend door is stuck. The shaft it swings on is metal, and over time they tend to rust and binde up, operated the temp knob while you look for or feel for the actuator that moves that door, some actuators ar vacuum operated, some electrical. Either these motors, called servo motors can go bad or the above mentioned issue! If the shaft is frozen, try a small drill bit at the base of the shaft, drill thru the plastic and spray some white lithium grease in there, if you can move it by hand, so much the better! Work it back and forth till it moves freely!
