1992 Acura Integra No heat

Check the heater control valve or the air blend door-

check the coolant level, then with the car hot, feel the heater hoses at the firewall. if they aren't hot and the coolants full, then the waterpump isn't pumping. if the are hot then the blend door isn't working. its a door like the one that changes level only it does temperature. its operated by a cable in this case.
