no heat could be a number of things, you could have a bad thermostat or a crack in the block. or even just a bubble in one of the lines, (coolant) better hope its the thermostat

If it's interior heat you are talking about, it could be the thermostat. If you find your temp gauge is fluctuating all over the place, change the thermostat. If not, it could be your heater core. You could try flushing it out.
Yes. Check that first. If you are not getting heat then it could also be a stuck thermostat.
A heat pump thermostat.
Could be that the thermostat is stuck open, new thermostat fixed my 2001 Dodge 3500. If your temperature gauge is not reading warm enough, could be the thermostat.
Heater core could be clogged.

First, is the thermostat in he correct position for cooling? Is there a red light glowing on the thermostat? There could have been a power surge or outage and the heat pump needs to reset. Turn the power off to the heat pump at the control panel for a couple or minutes then back on again to reset the heat pump.
Check coolant level Could be a weak thermostat
Could be a bad thermostat or heater core
