Heater problem
2004 Chrysler Sebring six cylinder front wheel drive automatic 90,000 miles.

Two weeks ago the seal to the plastic hose that goes from the overflow to the engine was replaced, now I do not have any heat in my car. Yesterday he tried to replace the knobs on the console and again no heat, then put more anti freeze in and blew up my radiator. Also, replaced the thermostat and still no heat. Now he tried telling me that my head gasket has a crack. Can someone tell me if this is all related?
What else can I do besides go to a real mechanic, about the heat?
Thank you.

Sorry to hear that
But I think you need to have the head gasket checked as all indicate to a bad gasket.
Try and bleed the system add more coolant.

Check coolant level as it is probably low. Then have system pressure checked for internal leaks.

Heat is intermittent sometimes the heater works than others it just stays cold the heater gauge on the dash raises. Do you think it is the thermostat?

Check your coolant lever first if low fill it and have it pressure checked for leaks.

With the engine at full operating temperature, locate the two heater hoses where they go into the firewall and feel them to see if they are both hot to the touch.
If you find that they are both too hot to hold, then the heat in that vehicle is controlled by a blend door that regulates heated air flow. It is operated by an electric motor/actuator. The problem can be that the actuator is stripped or inoperative or the door itself could be damaged. This is what needs to be determined by examining the actuator and see if it is responding to heat change commands or not.

Does the engine reach operating temperature?
If not remove and replace thermostat.
If it reaches operating temperature and no heat inside.
Check heater hoses by the firewall both should be hot if one is not heater core need to be flushed. If both hoses hot suspect blend door and or its actuator.

I have a 2004 Chrysler Seabring.
My heater in my car acts up off and on.
When I am driving the heater heats the car cab is fine, but when I am stopped in idle i.E. At a light or drive through the heater blows out cold air. Then when I start driving the heater starts putting out warm then hot air.

What is going wrong?

That sounds like the cooling system is low on antifreeze. It has a hard time circulating then until the water pump speeds up along with the engine. Check the level in the radiator after it cools down for a few minutes, and if it is low, add some to the reservoir too.

Heater problem
2004 Chrysler Sebring six cylinder front wheel drive automatic 68,000 miles.

My heater in my car does not work when I am sitting still with it running or usually driving under sixty or fifty miles an hour. After I have reached the mph point then it starts working, but as soon as I slow down below at least thirty it turns from warm to very cold air coming out of my vents.

I would suspect a vacuum leak somewhere on your control system. The vacuum source comes from either the intake manifold or a junction block on the firewall. I will be a small plastic tube, approx 3/16", and brightly colored, ie; Red, blue, black etc. Check this tube (hose) for vacuum. You are looking for cracks or splits. From here it could be either the heat control valve or the air blend damper. Not knowing if you have climate control or a manual temperature control system, this will cover the basics.

Engine Cooling problem

The loss of heat started when it was at an idle, it would come back when the car was moving, now it not getting hot at all.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
