2 possibilities. 1 - the heater system isnt getting adequate hot water flow from the engine and not heating the air for your heater to function. This can be due to a defective heater control water valve, a plugged heater core, a disconnected or plugged heater hose.
2 - the system is in fact getting heat, but your heat is bypassed/lost due to dashboard vent and blend door errors breakage common with that era of jeep. have the valve/cor/heater hose flow checked. If that doesnt show issues, have the vent control system checked for blend door or dash door breakage. beware, its alot of labor to change the dash solenoids when they brake, ALOT of labopr (6 hours or more!) so if you are committed to fixing it because a solenoid and/or sensor broke in there, I highly recommend you chaneg ALL solenoids wuith new rather than risk another breaking in a month and the 6 hours of labor must be repeated.

'98 Jeep Grand Cherokee - My Heat/AC worked intermittently for a few days and now blows only heat. Changing the Heat/AC settings doesn't change the temperature at all. It blows very hot. AC is still...


The control for the AC/Heater door isn't working. To have AC the door has to close so that the hot air is not being blown into the car. When this door is closed it allows the cool air to pass through. This is either controled by vacuum or a ele. switch
