There are several things that can cause heater problems in your 1998 Jeep Grain Cherokee. The most common cause of heater problems is low fluid in your cooling system.
On a 4.0L, yes one of the heater hoses does.
The heater core is inside the hvac housing under the dash.
Need more info like, is the blower working or not, is the air coming out cold or warm when it should be hot, is the air not coming out where it should be.
The HeaterTreater is an after market kit that solves heater and AC for the Jeep Grand Cherokee and Laredo. It is much cheaper than the dealership fix and is easy to install. For diagnosis and info, check out www.heatertreater.net or search eBay for "heatertreater".
if the rear ac is working then you probably have a damper door that is inoperative. this is in the heater/evaporator box. so if it isn't working then you will be heating and cooling at the same time out of the heater box.
Jeep Grand Cherokee was created in 1993.
