Bad thermostat, clogged heater core, or a defective heater control switch. If an engine has not been running long it will not have warmed up, the warmth from a car heater usually comes from the engine.
What do you mean by "has no heat"? No air blowing out, blowing out cold air when heater is on, blowing nothing at all? Heater not turning on? What specifically is happening?
One reason your home electric heater is blowing cold air is the heating elements are burned out. A bad thermostat may also be the problem.
faulty control valve on heater or air in the lines
Low coolant and a clogged heater core are possibilities.
Maybe its broken. Or maybe you pressed the AIR CONDITIONING
One of the reasons a 2000 Jeep Cherokee heater would randomly blow cold air and then hot air and then cold might be that there is a problem with the hot/cold duct. The air or a vent might be inadvertently blowing periodically.
You may need to replace your Thermostat or your Heater Core.

If you are saying the heater is blowing out cold air you need to change the heater core which is located inside the dash

I assume your car heater is blowing cold air, when the heater is on. It seems that, you have air on your coolant. that air pockets blocks the cooland to travel through your heater. it may be a sign of a bigger problem such as blown head gasket in the old cars, such acura legend
It is because your heater is having to heat up so its blowing cold air out while its heating up.This means your heater is not very efficient and it needs to be checked.
Only the fan is working, there is no gas burning (gas heater) or the electric heating element is not working(electric heater)Answeris it electric gas or oil Its gas.
Heater control valve stuck open. Possible blend air door failure.
it is a heater. heat. it blows heat. warm air
heater core plugged or air locked check to see if hoses going to heater core are hot
If you feel no air blowing at all (when you are not moving) then your fan is not blowing. If it is blowing air, and it is cold, when the heater is on, then most probably your heater core is leaking, or is clogged. These are easily replaceable and go bad all the time in older cars.
start by changing the thermostat
