I have a 2000 Dodge Dakota and I have replaced the heater core and the T-stat and I still do not have any heat. I burped the system and still no heat. The waterpump is less than a year old and I am stumped.I thought it was the Blend door but it was fine. Does anyone have a clue where to go next.

Are both heater core hoses getting hot?

If both hoses are getting hot, there is flow through the heater core. At this point, the blend air door has to be sticking. The door, located near the heater core, determines if you get heat of AC to the interior. If it is in the AC position, you will get no heat. Check that and let me know what you find.

I took it to my car guy and he said that the door was ok, he said that he took it apart and the door is right and functioning. This is one for the books.

If the heater core is circulating hot water (we established) and the blend air door is working, you should have heat. Was the tech able to give you any suggestions?

He said that it could possibly be a weak water pump, but I have drove the truck hard and it will not get above 200 degrees. If it was weak it would get hotter. And also the water pump is less than a year old.

A water pump will either work or not. There is a steel turbine in it that pumps the coolant through the system. If both heater core hoses are getting hot, there is hot coolant going through the heater core. I still say it has to do with the blend door. You may want to get a second opinion. Everything we have discussed points to that. Please keep in mind, I have no interest in making money from you. We are here to help. If the pump is almost new and it never goes above 200 °F, it is doing its job. Trust me.

Let me know.
