2005 Jeep Grand Cherokee - heat stopped working. Fan is working and it is not the pump or heating/cooling system
Heat was blowing hot and then it wasn't. It is not a radiator, thermostat or water pump problem. Is there a vent issue with these Jeeps?
Most likely it is a blend door, either it is broke or a servo motor has failed. Jeep's have a problem with these There is some information on them via you tube.
