Question about 2002 Jeep Grand Cherokee
First make sure the coolant level is full, This is a common problem, but often the doors are ok but the actuators are bad. The actuator for the driver's side is not hard to get to,,, the passenger side is a bear since the whole case has to come out. Pull the drivers side actuator and move the door manually to check your heat. If you cannot afford to do both, at least drivers side will put some heat in the car.

Temperature Control Blend Door Failure No Heat or no AC (dependes on
where door sticks)
all modern cars there is a tiny DC electric motor driven gear drive
that moves a plastic door that blends heated and cooled air from the
AC and the heater core, this is called (interestedly enough) the air
temperature control blend door actuator. The motor that moves this
door fails because the door starts sticking from warping, most common
complaint is no heat but it can be no AC as well. To replace these
parts (blend door and blend door actuator) you must remove the entire
dash from the car. Always have this problem confirmed by a dealer or
qualified repair shop as it is a very expensive repair.
Other causes of no heat in the cabin are engine thermostats that are stuck open (engine runs cold) or air bubbles in the cooling system.
