Either you are low on coolant and there is air in your heater core, or the thermostat isn't working properly, or your water pump is going out.

if there is not even luke warm air coming from the heater it may be caused by the blend air door motor. on some of the jeeps they came out with a new upper heater housing that was a new design. I believe if your vehicle had this update the dealer would be able to check TSB's for the cause. other wise like I said, most likely the blend air door and/or motor

Bad heater core or bad doors in heater box

clean its heater with air pressure or with blower.

Water level perhaps. When you hit the accelerator the water volume increases. Check your water level and make sure that your thermostat is opening and closing properly. Water level I'm thinking

Jeeps are notorious for having broken temperature control (Blend Air) doors. A malfunctioning Blend Air Door actuator probably caused it to break. The dash will have to be removed to replacethe door and the door actuator.

this sounds normal in very cold conditions! The air is never hot when you first start the car in any car, until the engine warms up, then the heater air will also warm. You could check your anti-freeze level for the first thing. If you don't have enough anti-freeze, it won't run through your heater to give you the proper heat

after checking the heater core hoses they were both hot I went in to look at the blend door and noticed it wasn't moving on hot or cold so I simply disconnected the lincage and moved to hot and its working ok. but its not completely repaired
