Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
Do you have air flow from the heater just no heat to it or no air flow at all?
Let me know so we can continue,thanks Pete.
O.k.,the evap temp sensor code would usually cut off air flow and since you have air flow this isnt causing the issue here with the heater.The biggest issue for no heat is the Duo valve which switches on to allow coolant into the heater core.This is located at the right rear of the engine compartment as shown below.Most likely this valve has failed needing replaced.
The other issue can be the heater core itself being restricted needing replaced or flushed out.If you locate this duo valve you can run the engine to temp and turn on heat and see if the hose on both sides of this valve are hot.If they are then the valve is o.k. Then locate the other hose coming from the heater core that is not connected to this valve and feel it.If it is not as hot as the hose coming from this valve then the heater core is plugged needing flushed or replaced.If one hose is hot at the duo valve and the other is cold or allot cooler then the duo valve needs replaced.
