Question about Chrysler Concorde
We have tried flushing the lines out, replacing the thermostat
That job is best left to an experienced mechanic. Basically, drop the steering column, then disassemble the dash enough that it can be moved back away from the firewall far enough to gain access to the heater/AC box. Removing the RH seat also helps.
If you opt to do this, it's highly recommended to also replace the AC evaporator at the same time.
Before tackling a major job like this, I'd recommend trying to seal it chemically by adding a jar of "Bar's Leaks" to the cooling system. Follow the directions on the container. This works more often than not.

Getting to a heater core can be a challenge. Best route is to go into local chain automotive store, and ask them to print you out a diagram, which will also give u a better look at what your dealing with

SOURCE: heater blowing cold air
squeeze the hoses to get any air bubbles out and refill coolant as necesary. are you sure you put thermostat in the right way? may be backwards. also may be your sensor.

SOURCE: 1997 F150 heater problem
your problem is caused by the air temperature control blend door actuator motor being defective, the little motor moves the door that gives either hot air or cold air or a blend of the 2.

You just might have an air lock. Try bleeding the system from the heater hose at the firewall. Losen one hose a little, and at operating temp. open slightly to let air out. You will lose some coolant, but just refill the rad. Now, both hoses should get hot.

Since your blower is working and it is a heat issue,thats where we'll
start,First thing is have you checked the coolant level in the radiator when
engine is cold,make sure it is filled to top,next verify you have coolant in
reserve ,Start your van and get it up to normal operation temperature,If your
heat gauge on the dash works correctly it should be 190 degrees,Now lift the
hood and locate the two heater hoses going into the heater assembly at the fire
wall,Both hoses should be hot to hold on to,if both are hot and no heat inside
your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.

I don't know your vehicle, but does it have a blower door tucked in where the heater core is? If it DOES and that's broken then it could be the whole problem. It would mean it isn't switching from the A/C side of things to the heat side of them. Hope this helps, good luck! Also, just looked up the proper name for what I'm talking about, it's called a "blend door" and I think your car has one. It's what I would check, again, good luck!
