We have no heat. Blowers are good. Flushed out heater core. Nothing came out but clear liquid. Filled radiator with correct antifreeze for vehicle. Temperature gauge goes up when running to 1/2, but still no heat.

More than likely the blend door actuator has failed. I attached the information about this and how to replace it. Sounds like you covered everything that would cause no heat that is related to the engine but the blend door is what directs the air over the heater core or not. More than likely it is stuck on the fully closed setting which doesn't allow any air to go over the heater core.
