System may have air trapped in it still. the gauge readings are just reference points and vary car to car and sender to sender.
Also Toyota's don't like after- market senders/sensors if that's what you might have installed.
Is the blower working correctly and if so is the air being directed to the proper vents?

 

The A/C blows good, air comes from proper vents. I did install aftermarket cheaper sensors.
EDIT: Could it be the blend door actuator, even though when I scale the temp up or down I see the thing rotate?
Today I'm going to drain all coolant, and thermostat and replace and see what happens winter is coming and I need the heater haha.

 

Replaced thermostat and coolant, it's working now. I guess my thermostat was just barely opening and closing. Thanks!

 

See, you didn't need any help!
Nice job.
