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

SOURCE: Heater blows cold air when idle

Sounds like you may have a partially plugged heater core. You could flush this out separately, from flushing radiator & engine block. Diconnect heater hoses going to your heater core and clamp off, so not to loose coolant from engine. Now hook up separate hose to one side of heater core pipe and flush out with typical garden hose. Repeat procedure on both heater core inlets. Reconnect original heater hoses and test difference. You may have to add an additional litre of antifreeze. If this don't work i suggest changing heater core. Good luck.........Ron.

SOURCE: 2003 Jeep Liberty heater fan problem

It is the blower motor resistor. Look under the passanger side dash and locate the fan housing (looks round and black in color. Then locate the resistor it will be in that housing usually withtwo ten millimeter nuts or two simple screws holding it in. unplug the harness to the resistor and remove the resistor. Part store price is approx. 50.00. Note: on aftermarket (not Jeep) resistor sometimes you have to modify the housing a little to get it in. Hope this helps.

2005 jeep liberty blows cold air through the heater.


could be the thermostat if it was just stating to go bad,could also be a vacume problem not letting the door for the ac/heat close all the way for a few min.and if its really cold out like below 35,then its going to take longer to warm up,my jeep takes like around 20 min at idle to warm up.yours could be a case of over cooling in cold weather too ie(electric fans on before it warms up)that would be the thermostatic sensor.

My 2003 Jeep Liberty heater is blowing cold air when idling. Warms up when you hit the accelerator. I also hear a water rolling sound upon take off after idling. Water pump? Heater Core?


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

I have a 2002 Jeep Liberty Limited, 3.7 L motor. The heater will not blow hot air. The A/C and fan work well. When I turn the temperature dial to hot, there is only cold air coming out. Can you assist me?


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.
