Default heater blowing cool air

I have a 2000 dodge durango and the heater quit blowing hot air. The thermostat is working normal, radiator is normal, felt both hoses going in and coming out of the heater core and they are both hot and not leaking inside.Everything seems to be working like it should but will not blow hot air. Can someone PLEASE help . Thanks in advance.

You probably just need to do a reverse flush on the heater core. 1/16" of scale buildupis like 2" of metal as far as heat transfer goes.

I likedshrpshtr answer.

Reverse flush the heater core. Search the forum in the Durango 1st generation for great information on this very issue.
