Question about Jeep 2006 Commander Limited 4WD
I can think of two possible causes 1 very serious the other no cause for concern just uncomfortable in winter time. the first and most serious is that your radiator is out of water. your heater circulates engine coolant thru your engine and heater core from your cooling system for your engine. if no water there isnt anything to flow thru engine so no heat. simple enough if this is the case you probably have a good leak somewhere in your cooling system ie hose or water pump or radiator its self. the second possibility is that if car is used and or there has been work done on the car then probably the heayer core has been bypassed the reason for doing this is because the heater core is located deep inside the dashboard and in- side of fire wall. part is cheap but labor hours are long and expensive usually around 5 hours at $88.+ an hour it is just cheaper to undo the radiator hose that flows coolant from your engine into the heater core and bypass the hose to just flow straight back in to the engine. this will keep engine from overheating and make your heater blow straight outside or vent air. btw if you have a leak in cooling system get repaired asap obviously over heating will cause catastrophic engine failure. hope this help
