Question about 2004 Jeep Grand Cherokee
My 2004 Jeep Grand Cherokee with 6 cyl engine has no heat. Car warms up and operates at normal temp but heat just blows cold. Fan works - any Idea what I can check.
If jeep is a limited model it has automatic temp control for the heater blend door, it is controled by a electric motor, and can be problematic with age,sometimes it makes a clicking noise when the blend door is stiff ,which then it must be lubed and freed up

Either the heater core is plugged or partially plugged, the heater control valve is not opening completely or the thermostat isn't allowing the engine to warm as much as it should. Even though the engine seems warm enough, if the thermostat isn't working properly you may not be all the way up to temperature.
