    I should have mentioned when i turn the heater down to cold it does go cold but then back to hot only get warm. not sure if this makes any difference but was told i should mention it . is there a way to tell if the blend doors are working correctly ? no #'s on the gauge just the c and and h . Thank u so much for the help

    I actually noticed the fan come on then back off then came on a bit later then back off yesterday night so that seems to be working right

    Are there numbers on the gauge? Half way up is probably OK. (temp is temperature on the gauge) That eliminatifies the thermostat. There are doors inside the black box that goes from the passenger side almost to your "gas foot." one of those doors may be staying part way open.They are called blend doors there are little brass things with a vacuum hose on one end about the size of a 35mm film cannister that move the doors. they are called motors (but they are really not motors) if they dont move at some point when working temp control then one is broken. OR, another question: is the electric fan on the radiator on all the time with the a/c off? It should only come on for a short time, then go off. And should never be on when engine is cold. You may want to check that.

    private party?I'm insulted that I wasn't invited! Or are they having a private party with the money you gave them?
    OK, first thing you need to check is if engine is coming up to temp when running... Which engine? Most run at about 210 if not thermostat may be either missing or stuck open...
    Won't jam you with too much info all at once. check this first, don't check yourself in till were done!!!

Well, if the electric radiator fan isn't staying on, it pretty much has to be in the heater box. You may have a heater control valve on one of the hoses that go into the heater, but generally default on those is full heat. that leaves ether a blend door problem, an obstruction blocking air flow through the heater core (leaves, mouse nest or other) a blend door with partial movement, or a semi-plugged heater core (internal, inhibiting coolant flow). Since this is usually a long and involved job, you may want to find someone local that can help you." Hands-on" I can deal with almost anything but alas! I am too far away!! One more thing...If you have automatic climate control, see if there is a small (about the size of a quarter) vent somewhere on the lower dash anywhere. there is a sensor in there that may be dirty.(in the hose behind it)
Well it's getting late, its all darkified outside! Got to walk my doggie and go to sleep. I'ts 2AM!!! Good luck with it, wish I could help more!!!

2002 jeep liberty heat only works at high rpm


Sounds like low flow issue. Flush and clean system, PROPERLY! Buy a flush kit, drain system, blow compressed air through, fill with cleaner/water mix, run for 30 min with heat on, drain system, blow out with compressed air, fill with water, run for 30 min, drain, blow out with compressed air, fill with 60% coolant mix.

My libertys heater only blows heat when I'm giving


first off all if a/c gas presssure is low or no gas at all ( because of some reason you have already lost it) it acts exactly how you you describe. kicks in and out. but cant cool air inside. (first make dealer check it for leaks and let them fill it with proper yellow flourescent dye added gas)

limited het in cabin heater is another issue. if engine is warm and still not enough heat inside, we can say that you have a clogged cabin heater or air pocket is in hoses connected to cabin heater. you need to bleed cooler radiator inm front. you need to raise infront of car and bleed it with bleeding screw. after this check the heat again if still not enouh heat you may need to replace cabin heater.

if engine is not warm enough when you drive slow or let it idle. this means you have a broken thermostate or it is stuck half open.

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.

I had the heater and radiator flushed out it blows warm air but it never gets hot


Most repair shops when they do a complete flush out...they take out the thermostat. No thermostat will never get engine hot.

I have a 2002 Jeep Liberty and after driving for about 30 minutes the air conditioner would start to blow hot air. The air conditioner clutch was sticking. I could hit the clutch and it would kick in and start to work. I went to Advance Auto and purchased a big spray can of electric motor cleaner and a big spray can of WD-40. I soaked the clutch with the electric motor cleaner, used the whole can, then soaked it with half a can of WD-40. The clutch has worked perfecty ever since.
