Hi Paul, check the engine coolant level, the thermostat and the valve operation which controls the coolant going into the cabin heater. The most likely problem would be with the heater regulator valve.You'll find that located on the fire wall between the engine and cabin. It will have two hoses and an adjustment device fitted. It very well may be stuck. Regards John
