Question about 2011 Jeep Liberty
Heater blows cold
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

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.

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.
