No heat

I have a 2017 ram 1500 ecodiesel that has no heat. Sometimes it will work and other times it won't. I have checked the coolant levels, replaced the thermostat, and replaced the 3 way valve. None of which seem to be the problem. I'm not sure what else it is and need help.

Do you mean the engine isn't getting hot/coming up to temp? Or no heat in the cab?
If it's no heat in the cab, does it have the auto climate controls? If so, could be one of the sensors for that unit malfunctioning.

Engine warms up just fine but it just blows cold air in the cab. No heat will circulate through the heater core. It does have auto climate controls.
