Hot air blows out on passenger side of truck/but verry little. On drivers side, cold air blows out with extreme force. Defrost blows out warm air. Temp guage in the truck reads normal.I had the radiator flushed, no difference. Any thoughts?

The vent doors are actuated by an motorized actuator it sounds like the mode actuator for the passengers side is out but you can check each of their operation and replace the one that is not working here it the location of each in the diagrams below with a guide that can help as well.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
