It could be a number of things could be the problem. I would check them from easy to hard.
1. Radiator: After it is warm, not hot, open filler and look to see if there is circulation also rust deposited. May need flushing/cleaning. You can also determine circulation by feeling the outside of your radiator hoses. If both are equally warm, signs of good circulation. If the hose, after/past the engine thermostat, is cold = circulation problem.
2. Thermostat: You may have a stuck thermostat. If the hose on the other side is cold or cooler it indicates a closed or partially open thermostat. Change it.
3. Heater Core: This could be the most difficult to fix/reach. If you can feel the hoses on either side of the core. If one is colder than the other it may need changing or cleaning. You also could have a heater door/flap stuck shut.
Good luck.

There is a fan (usually in the dash) that blows the outside air over a small radiator that is known as the heater core. If the heater core is disconnected (which is found to be the case on many vehicles) there is no heat for the fan to blow the air across, so you are getting the raw outside air. Usually, there are two hoses going from the engine and/or radiator and going through the firewall on the passenger side. See if you can find these two hoses, or holes, from the firewall and see where they do or do not go. Also, they may have been disconnected because your heater core was leaking. I'm looking at a pic of an engine compartment of a 1989 Jeep Cherokee right now...this Cherokee has a "straight-six" or, an in-line 6 cylinder (http://www.cardomain.com/ride/475777). In this picture, there are two red hoses going from the front of the engine to the passenger side firewall. Those are for the heater core. You need to find a similar set of hoses on yours and see if they have been cut and plugged or removed or what.

i own a repair shop,in Tennessee,and id check the coolant level first in it,then you might want to check and see if the thermostat might be stuck open on it,this is the most common cause of no heat,and also it might have a bad inside control unit on it causing it not to change from cool to heat,i have replaced a lot of those this year already,id say that may e it though ,given the year of it ad it probably has a few miles on it to,but these are the most common things ,other than the heater core being plugged up on it,,good luck, i hope this help,s.

immediately check the coolant level in the engine. low coolant level can make a heater blow cold air as the heated engine coolant flows thru the heater core to supply heat for the interior of the car. if the coolant is low you may severely damage or destroy the engine by driving. if the coolant is low, find the leak and fix it. if the coolant is not low, the heater core could be plugged or the temp switch on the dash could be malfunctioning.

A plugged heater core is the most likely culprit. That's what I would check first.

the water valve is opened by vacuum, there is a storage tank in the right side of front bumper, it is prone to damage also the vacuum hoses where they pass beside battery can corrode and split, the water valve itself may be bad or heater core could be stopped up.

Sounds like your heater core is dead. This will have to be replaced if you plan to stay warm in the winter.
