2000 Cherokee not warm

I have a 2000 Cherokee Sport, used to have great heat, now is lukewarm. Flushed radiator & heater core, replaced hoses, still minimal heat and a minor leak of antifreeze. Suggestions before I spend money for someone else to look at it?

    My 2000 grand cherokee is blowing warm air on the passenger side and cold air on the driver side when the heat is on. I replaced a leaking radiator back in the summer. I also get a odor of coolant in my car.

Aside from flushing the radiator and heater core andreplacing your hoses, did you happen to replace your thermostat. Sounds to me like that's your problem if everything else seems to be in order. If you change the thermostat and still have no heat, you might check your vacuum lines running to the back of your heater controls inside your dash. That's really the only other thing that I believe could be causing your lack of heat.

Hope this helps! Have a great day and try to stay warm!

Dodge neon overheating


I would be thinking radiator or water pump. When the engine is warmed up and the upper hose is hot, feel the lower radiator hose. It should be hot too, just a little cooler than the upper hose. If there is some blockage in the radiator, the lower hose may feel cold or just lukewarm.
Even though the water pump doesn't leak, the impellers may be made of plastic and have considerable wear. That would restrict circulation.
The heater core should not be an issue. Heater cores do not cause overheating even when totally plugged up.

Heater does not come on, Radiator fluid full. Fluid heats, heater does not work blower works heater does not get hot or even warm.


Probably air locked. check to see if one of the hoses leading into heater is hot. Other cause could be heater solenoid control valve faulty. Very unlikely that the heater matrix is blocked. Easiest way to bleed heater is to remove hose's when car is cold and GENTLY flush through with garden hose and push hoses back on when full of water, so you know you have a heater full of fluid. Hope this helps

I HAVE A 95 JEEP GRAND CHEROKEE AND ALL I GET IS LUKEWARM AIR WE HAVE FLUSHED THE SYSTEM CHANGED THE THERMOSTAT, RADITOR CAP AND HOSE, WATER PUMP NO CANGE WHAT ELSE CAN I do?


If your gauge is showing correct operating temperature and you are getting no heat from the heater, check (just feel them) the hoses leading from under the hood through the firewall that service the heater. One should be uncomfortably hot, the other only warm. If they are pretty close to equal or even cool, you have an obstruction in the heater hoses. Rubber hoses in the cooling/heating system are made up of laminated layers and if aged enough, the inner lining can separate and collapse blocking the flow of water either to or from the heater core. Sometimes, if bad enough, squeezing the hoses by hand can even locate the failed section; it will be noticeably weaker than the rest.

99 jeep cherokee problem w/ heat I replaced the blower motor, water pump,radiator, thermostat and flushed the coolent system. Still getting little heat. I'm thinking heater core or head gasket... Is there...


It sounds like the heater coil needs flushing out or replacing or the heater valve. Look on the engine firewall and make sure the heater valve is opening. If not open it manually and check the heat level. If that produced heat check the condition of the heater vale cable (or vaccum hose).

once truck is warm check both heater core hoses to make sure they are both warm if not then check the cold water valve could be stuck shut not allowing coolant to travel in to heater core.

No heat


The likely culprit is your heater core. Simple test: Let you car warm up to Operating Temp. Run the heater. Under the hood on the fire wall you will see 2 black hoses conected to 2 aluminum lines about a 1/4 inch in size, feel both of these if they are not the same temp than you have a clog in the core and as a result no heat in car.

Heater only blows warm air.


The hoses from your heater core should be very hot to the touch. Check the hoses going to the core from the water pump. It should be very hot. The return hose should also be very hot. Now check the hoses going to the core. If they are not the same temp, then your heater control valve is not working correctly or the vacuum is not working. At any rate, locate the vacuum line going to the heater valve. Remove the silver bar on the valve from the plastic plunger arm. You will have heat all the time now if it was only a vacuum problem. You can fix it later when it's warmer out. BTW a 200* thermostat will make your heater even hotter.
