I have a 2000 chrysler concorde, the heat stopped working after the car did not want to start because of a bad connection in the positive battery cable.
I drained, flushed and bled the cooling system, thinking it my be clogged, still no heat.
I also replaced the heater resiter under the right side of the dash, same result.
What could it be?

Are you saying nothing blows through the vent or the air blows but isn't hot?

I need you to check something for me. With the engine hot, running, and the heater on high, do both heater core hoses get hot?
