This is a common problem with this series of vehicles. Another likely cause of a car that runs ok, but has no heat is a stuck thermostat. This is the actuators in the havc system doing a rest.

If it is stuck, it may be allowing the coolant to always be run through the radiator, which keeps it too cool to allow for heat in the cabin but will still allow the vehicle to run.

If your system has a bleed port or bleed screw, and you can find it, you can fix this air lock yourself.
