Grand Cherokee Heater

have a 2002 grand cherokee limited with heater problems,everything works but does not put out any heat?

dealer said something about the unit that shows outside temp.was wrong ,it was gotten used in naples fla.and my daughter never got any extended warr. and now they say they can not help her,shes only had it 2 months and will cost about 1300.00 to fix.does this sound like the problem?

My first thoughts are:

1) stuck thermostat
2) leak in the cooling system
3) heater core is shot
4) cracked engine head or blown gasket
