Even if the heater valve is closed, the likelihood of condensation within the heater matrix is exceedingly small -- too much heat from the coolant to allow that. Look for a leak -- it has fixed every one of these situations that I have met. Except for A/C vehicles where the condensation does form (on the evaporator core) before the heater core has a chance to warm it up.
