The heat comes from the engine coolant/antifreeze. first check to see that the coolant is full. if not top it off and recheck the heater. if it is full, the heater core may be plugged. the coolant gets hot from the engine and goes through the heater core. the heater core is like a tiny radiator. the heat from the coolant transfers to the heater core and it gets hot. then the blower motor (thats the fan that blows the air into the jeep) blows air over the heater core to heat the air up and warm the inside of your jeep. if it is plugged you won't get any heat. no easy way to test for that though. the thermostat may need to be replaced. that part controls the flow of coolant into the engine to regulate the temperature of the engine. if it is stuck open the coolant won't get hot enough for the heater to work. if your jeep has a engine temperature guage you should notice that the engine doesn't get very warm. if the thermostat is stuck closed the coolant won't get into the engine to be heated up. again, if there is an engine temp guage it will show the engine is heating up quickly and running too hot. usually the engine will overheat if thats the case. it could also be stuck part way open. this will cause the engine to heat slowly at first, then overheat. the thermostat is probably the most common cause of the heat not working properly. the good news is that this is probably the least expensive repair to resolve the issue. that is unless the engine overheats and some crucial engine components get damaged. good luck! i hope i was helpful.

there are alot of correct possible awnsers, the thermostat could be partially opening, enough to let water pass so that the engine doenst overheat but not enuff to blow hot heat. there could be a clogged heater core(flush and back flush to fix that). The doors in your heating duct that open and close when u switch from vent to defrost may not be opening all the way (there is a metal cable on the passenger floor under the glove box that controls that)....

first question is was it blowing warm air before or has it blown cold every time?
if it's the first then, it could be the heater core that is not circulating the radiator fluid or it could be the temperature switch is not working right. if it's the last then, check to make sure that your heater hoses are connected. it's hard to say what may be wrong without looking at it.

It could be that you have air in the cooling sytem. You could also have a bad heater control valve or a clogged heater core..or even a malfunctioning HVAC system.
