Question about 2002 Jeep Grand Cherokee
The heater has began to blow cold. At 1st the passenger side was colder then the driver's. Now both sides are cold. It sounds like the blend doors are bad but thats not it.
I cut into the housing behind the glove box and inspected the blend doors, they are and work fine. I flushed the complete cooling system and everything flows freely even the heater core. Next I put in a new thermostat and thought that was the cure but not so. I don't know what else it could be. Any Ideas?
If ythe heater core is not bad then I would replace the thermostat, this will stop the warm coolant running up to your engine go to the heater core.
