    It sounds as if the temperature door actuator is stuck in the cold position, but A clogged heater core would not be uncommon so make sure both the inlet and outlet heater hoses are hot! Service information states the dash must be removed to replace the temp door actuator. It is on top of the heater box. You may be able to access it by removing the glove box.

    Thanks much for the information...both heater hoses are hot, so I can safely assume water is travelling thru?

    Yes, If both heater hoses are hot to the touch then you can assume coolant is flowing through the heater core.
