Question about 1998 Jeep Cherokee

Heater in 97 Jeep Wrangler does not get warm when it is very cold

It does not have a problem when it is 40 degrees, but below that it blows mainly cold air. Also the temp gauge does not stay pointing straight up ( in the middle) unless I am at about 3000 RPMs.

Could be; thermostat, plugged heater coil, or maybe you're just low on coolant. If you have enough coolant, then change your thermostat. It costs like 4 bucks and should only take you about 15 minutes. Then, flush your heater core by disconnecting the two hoses and running water through one with a garden hose until water comes out the other, then reverse it after a minute or two. Do this a couple of times. You can also buy some flushing solution to do this with if it looks bad. I had the same problem and it turns out I was just low on coolant. I had a slow leak in my radiator and after I replaced it and had the right level of coolant I had nice toasty heat again.

    no they arent hard to change at all follow the top radiator hose to the motor and youll find the housig for the thermostat there at the end. its held in by 2 botls and when you put in the new one make sure you get a new gasket and clean off all the old gasket materials that will be on the housing and where it bolts up so you wont have any leaks.it takes about 45 minutes to change it out

2005 jeep wrangler blows warm air not cold


Well this is different since most questions now are about no heat.
If one ac line is cold and the other is warm, I would suspect a blend door under the dash is not working. The blend doors direct air thru the heater core and the vents.

2005 jeep liberty blows cold air through the heater.


could be the thermostat if it was just stating to go bad,could also be a vacume problem not letting the door for the ac/heat close all the way for a few min.and if its really cold out like below 35,then its going to take longer to warm up,my jeep takes like around 20 min at idle to warm up.yours could be a case of over cooling in cold weather too ie(electric fans on before it warms up)that would be the thermostatic sensor.

1999 Jeep Wrangler - 4cyl - 5 speed. Where do I start if my heater is not getting hot. Really doesn't get warm. Just blows out cool air. Side note: This is my 3rd winter with this Jeep and it's never...


The temp reading on the dash is a very big clue... Likely the thermostat (at the end of the large top radiator hose inside the metal housing) is stuck open. When that happens, the coolant in the engine never reaches full temp. Not only can that result in a low heat condition but it can also give you poor fuel mileage as the computer always thinks the engine is cold and therefore it adds extra fuel to keep it running.
Replace with a 195 degree(f) thermostat, run the engine (with the heater on full heat) to nearly normal temp, turn it off and wait about three minutes, then re-start and continue filling. Once full, add whatever is necessary to the recovery bottle and close it up and check for leaks.

95 Jeep Wrangler YJ...No heat, temp at about


It should be 200 degrees. If your running cold the only thing that regulates temp is the thermostat. If it is indeed 150 degrees thats why you have no heat.

If you replaced the water pump and the radiator for this condition then it was a waste of money. If you had a water pump or radiator problem it would overheat.

The fact that your blowing cold air tells me the that you really are 150 degrees or the heater core is plugged.

1998 Jeep Wrangler not blowing hot air. Fan is blowing cold air. Suggestions?


your heater hose or heater core could be plug, or your flap that opens inside of the heater housing may not be opening like it should. It operates off a vacum line, check all your vacum lines going into your heater housing.
good luck

1992 Jeep Wrangler heater not blowing hot air


How often has the coolant been changed? My only guess is that it hasn't and the hoses and the heater core are plugged up with goo and a flush is needed

Try this disconnect the heater hoses from the heater core use a hose to backflush the core. Then reconnect and try again.
