This is a very complex procedure and one not really to be done outside of a dealership as the dash and interior require removal to gain access to heater core

Overheating while Eating


Bad themostat, dirty radiator (the front of it), corroded interior core of the radiator, weakening water pump, bad radiator fan.....just to name a few. More than likely? Low antifreeze level, or the thermostat.

How to change a heater core in a 93 jeep grand cherokee


When I turn my heater on, after my 1993 Jeep Grand Cherokee has warmed up, there is a dusty, watery smell for a few minutes, then it goes away. Also, it doesn't put out as much heat as I think it should. I don't think the heater core has a leak, because I always seem to have the same amount of coolant in the radiator and the heater core is not leaking on the inside of the truck.

The fan works but my 2002 jeep grand cherokee wont blow heat what is wrong


It could be the thermostat or a plugged heater core. Check hoses going in to firewall after the vehicle has reached operating temperature for a drastic change in temperature if one hose is hot and the other cold or just warm your heater core could be plugged and would need to be flushed.

Heater core 2002 jeep grand cher.


I purchased a Blen Door repair kit. for my 2002 Jeep Grand Cherokee after having only cold air blow out of the passenger side for over a year. I found it on EBay. It requires you remove the glove box, cut open the heater box and replace the blend door. I really didn't want to cut that open, however, with the tape that comes with it, I have had no problems with it leaking any air. The dual control no longer works, the temperature is now completely controlled by the drivers side, but to save $1200, I was willing to do this. I have taken the entire thing out before to replace the heater core, didn't want to do it again.
