I would suggest replacing the heater core only if you have a puddle of coolant on the passenger side floorboard. More likely the problem is with the blend door not directing air through the core. This is a very common failure on the GC. Check the web site at heatertreater (.net) for diagnostic procedures and a cheap, easy fix.

The blender doors could be a possiblility. Jeep Grand Cherokees have a faulty blender door that breaks easily and doesn't distribute heat evenly, therefore, causing basically no heat. The cost can be very high, since the dash has to be taken apart. Approx. $800.00
