Hello - sorry you are having problem with your car. It appears by your post you are pretty frustrated. If so. That's understanding. Let's take a look at this.
Heater Core and no heat.
First, you must make sure there is no air in the system. If there is air in the system the temp guage will go up but cool air from the heater since it is not circulating past the thermostat.
Is the temp gage in the car getting hotter than normal or not hot at all or lower than normal? If the temp guage is not getting hot at all the thermostat is stuck open and needs to be changed.
Are the radiator hoses hot after the car is warmed up?
Are the heater hoses going into the core by the firewall hot?
The system needs to be flushed really well. Are you running DEX-COOL? There is a TSB discussing engines running hot but cold air from the heater due to being plugged with rust like material.
Change our radiator cap also.
Next the radio.
Have you checked the codes on the car and are there any? You could go to Auto Zone or O'Reilly's and for free they can pull the codes to the car. Most important. Once they check your codes, if they find something and you don't get it fixed and need to get back with us, please make sure you tell us exactly what the code was, number and all. Example, if the code was E0568 O2 Sensor bad. Then make sure you give us all of that. While there for free also they can bring their tester out and check your battery, alternator and starter.
I will have to get back with you on the radio etc. Check the other items on heating. I do believe the item unplug is causing you a problem. You have an Accessory delay module that keeps the radio on etc until the doors are opened. That is not functioning properly. We will have to look at that but for now, see if you can find where that plug goes, check the heating items above and get the codes.
