PONTIAC FIREBIRD DOOR PROBLEM

1991 Pontiac Firebird • 120,000 miles

After replacing my heater core, I still get no heat. I have good flow from the water pump and my thermostat opens and closes.?

You probably have a heater door or blend door issue. When you change the air control from hot to cold do you hear any noise under the dash? Like something opening or closing?

Homer. That happens to me. Like somethings opening closing loud. No hot air and car never overheats.
