what can cause me not to have any heat on my 99 cheroke .new heater core and thermostat
Sounds like you need to burb the cooling system there is probly a air lock in it. start the engine and open the radiator cap and put the heater on defrost and turn heat all the way up and watch the coolent level and add as needed needs to get up to operating temp on the gauge you should be able to see in the radiator when the thermistate opens. when it burbs it may kick anti freeze back out so be care full to not get burned
Allso make sure you have the hoses hooked up correctly
if its a limited it might be your blend doors. check out bled door aftermarket repair on you tube. We sell tons of 99 to 04 jeeps and its a common issue
