Hi chub

Remove the panel where the switch to the heater control is. Locate the heater box and find the air duct pathway. Check if any cables are loose, broken and see if the duct doors are working properly. If memory serves; the front grille , right side instrument panel, and a tube have to be removed to gain access to the motor. Once the motor is in view, you can see where the air flow pathway is and can effect repair as needed.

post back your findings.
