Sounds like a similar problem to the one I have - passenger side is nice and warm but centre vents and drivers side stay cold.

It is a know weak spot on the Grand Cherokee - the blend doors have a weak connection to the actuators and break. Jeep have modified the housing and components as a result but it seems to be a huge job to repair. Full dashboard out, degas the aircon and replace the parts.

The Americans seem to be paying about $1200 for the repair  :shock:

Thank goodness for heated seats!
