Question about 1998 Jeep Cherokee

1 Answer

Heater not heating my Jeep

I've changed the thermostat a couple of times, core not leaking,..When I put the fan on to blow in the two low settings, barely any warm air comes out, but it is a little warm...when I put the fan on high, it is all cold air...In cold temperatures, this is too hard to take...What could be the problem?
Temperature on the gauge goes to the middle, where it should be....No problems with overheating etc... My Jeep is really a 1997 TJ Sport, but the products below didn't have that so I picked the next one closest to my Jeep..

    Same problem after changing thermostat On 99-2000 Jeep TJ
    Topped up coolant and still only Luke warm air...? could be air trapped in the hose close to firewall I was told.. But I think the Blend door is the answer

    I have the same problem. Auto Zone told me to check to see if both heater hoses are hot, only one is. He said something about a switch that may be bad?? or is the core clogged? How can I tell what it is? It's 5 degrees here today and this is begining to be a problem. I just bought this 3 weeks ago. I love this Jeep. 1999 Cherokee

The problem is the air temperture control door (known as a blend door) is stuck or the door's actuator is not working. your engine temp is correct and not the problem.

SOURCE: I recently had the heater core replaced on my 2000

I would return the vehicle to where the work was done. It sounds like something such as the blend door was not reinstalled properly, or something wasn't reconnected properly.

Dual climent control not working will not put out any heat

Try the code trick, turn your ignition on and off, but not to the point that it starts 3 times- cycling the ignition key On - Off - On - Off - On- within 5 second or so you'll get some numbers on the odometer, record them and google the codes, or buy a cheap code reader....Your right around the year that doesn't work, but it can't hurt to try....

Is it blowing at all -and the way it is suppose to? Do you get it after driving awhile? Is anything leaking-even just a bit?

Check for enough coolant in the radiator(hear a gurgling?-low coolant) enough?Yes->check all hoses for cracks, splits, leaks,)all ok? Yes->-are the heater hoses hot after running a bit? yes?->flush the heater core, still nothing?-change the temp sensor..

That should keep you busy a while..

I'm getting luke warm heat coming out of my 2001 jeep, cool that you have to turn the vent away from you because how cool it is. I use to get burning hot heat, so i had my heater core replaced twice but...

Have you checked your water temperature sensor? A little thing like that can affect the heat put out with low readings coming out if it is not giving the right voltage. They are under $20 so that should help you out. The Jeep brand is originally AMC(American Motors Corporation) of wich the parts utilized came from different american brands (Alternator from Chevy or Ford, Motor from Dodge, etc.) But the put out for the heater core is the same. Just get the temp sensor changed and run the appropriate coolant for your Jeep year.

Heater wont work in my 1999 jeep cherokee sport. The fan blows but wont get warm. Does not leak in the floorboard as some do. Was wondering if there is a fuse for the heater?

One or more of:

1. Your coolant level is low
2. Your thermostat doesn't close and needs to be replaced
3. The valve from the cooling system to the heater core is stuck
4. Your heater core is clogged

I already changed the thermostat on my 2002 Jeep Cherokee and the heat actually seemed like it was working but now it is not blowing any heat at all. What could be the problem?

Air in the system or a clogged heater core. If it's air in the system, it needs to be burped. Click on my screenname, go down to Tips and Tricks, and follow the tip there on how to do so.

If the heater core is clogged, you'll need to blow it free. Follow the two heater core hoses from the firewall out to the engine. Disconnect them both, put one in a bucket, and use the blowgun attachment for an air compressor to blow into the other one. Then swap - put the one you blew into, in the bucket, and blow into the one that was in the bucket the first time. Reconnect the heater core hoses, and burp the system (again, follow the Tip instructions for that). Usually that will take care of it.

The heat in my 1992 Jeep Wangler is not working.

The only reason it won't blow hot air is because the water is not getting to the heater core. Check to see if you have a heater control valve in one of the two lines to the heater core. If so check to be sure that is is opening and closing. If it won't open then you get no water flow in to the heater core.

CHEVI LUMINA 2001 HEATER failing...might have slow dex-cool leak

The heater in your car depends upon a flow of hot coolant going through the heater core in order to get hot air into the car. If the heater core is partially plugged, it will restrict the flow.

If you have a head gasket that is putting exhaust into the cooling system, it will eventually get into the heater core. When this happens there is no coolant in the heater core to make the air warm.

If the water pump vanes have corroded away the result will be very poor coolant circulation causing the heater to not blow hot air.

If your car is equipped with a heater control valve that is not functioning properly, the coolant flow will be restricted.

One or a combination of these factors is likely the culprit in your case.

Flush the heater core 2-3 times, and if the obstruction does not clear, a new heater core is required.

However in your case, a cracked head is suspected - this will give out a plume of white smoke on startup - There is no smell, carpet dampness, or abundant moisture in the cabin? (this warns of a leaking heater core)

The coolant is leaking through a gasket or crack, and entering the combustion chamber. You dont see a leak on the ground because it is being burned up with the fuel.

Good Luck, and thanks for using FixYa - A FixYa rating is appreciated!!

96 Jeep Country-Heater blowing warm; NOT hot

unless you got visable signs of leakage its not heater core, but it could be pluged with sediment. take off both heater hoses and flush it both ways until it runs clear. you can also mix a little baking soda and water and pour in core and let set for a while and then flush.

Low heat coming from heater

heater core may be clogged. disconnect the hoses. CUT THEM OFF THE HEATER CORE!!!! If you pull them you may damage the solder joints at the tubes causing a leak. Them connect a garden hose and flush one way then another till water runs clear.
